Delia Derbyshire: Early Electro Artist

February 11, 2009

delia2

Delia Derbyshire was born in Coventry, England, in 1937. Educated at Coventry Grammar School and Girton College, Cambridge, where she was awarded a degree in mathematics and music.

In 1959, on approaching Decca records, Delia was told that the company DID NOT employ women in their recording studios, so she went to work for the UN in Geneva before returning to London to work for music publishers Boosey & Hawkes.

Derbyshire was born in Coventry, UK. Educated at Barr’s Hill School, Derbyshire then completed a degree in mathematics and music at Girton College, Cambridge.In 1959 she applied for a position at Decca Records only to be told that the company did not employ women in their recording studios.Instead she took a position at the UN in Geneva, soon returning to London to work for music publishers Boosey & Hawkes.

Some of her most acclaimed work was done in the 1960s in collaboration with the British artist and playwright Barry Bermange, for the Third Programme (the radio station which later evolved into BBC Radio 3). Besides the Doctor Who theme, Derbyshire also composed and produced scores, incidental pieces and themes for nearly 200 BBC Radio and BBC TV programmes. A selection of some of her best 1960s electronic music creations for the BBC can be found on the album BBC Radiophonic Music (BBC Records), which was re-released on CD in 2002. Several of the smaller pieces that Derbyshire created at the Radiophonic Workshop were used for many years as incidental music by the BBC and other broadcasters, including the ABC

Doctor Who

In 1963, Ron Grainer was asked to compose the theme tune to the Doctor Who series that began late in that year. As part of the BBC’s Radiophonic Workshop, Derbyshire developed his written notes into the version that was then used on the original show.

Ron Grainer was so amazed by her rendition of his notes that he attempted to get her a co-composer credit, but this was prevented by BBC bureaucracy, who preferred to keep the members of the Workshop anonymous. Derbyshire’s interpretation of Grainer’s theme used electronic oscillators and magnetic audio tape editing (including tape loops and reverse tape effects) to create an eerie and unearthly sound that was quite unlike anything that had been heard before. Derbyshire’s original Doctor Who theme is one of the first television themes to be created and produced by entirely electronic means.

In 1960 Delia joined the BBC as a trainee studio manager. She excelled in this field, but when it became apparent that the fledgling Radiophonic Workshop was under the same operational umbrella, she asked for an attachment there – an unheard of request, but one which was, nonetheless,granted. Delia remained ‘temporarily attached’ for years, regularly deputising for the Head, and influencing many of her trainee colleagues.

This excerpt from an interview, originally conducted in December 1999, first appeared in Surface magazine in May 2000.

What was your route into music? Did you study music at school?

Delia Derbyshire: No, but I studied piano to performer level outside school. I went to Cambridge University to read mathematics, which was quite something for a working-class girl from Coventry, because Cambridge was at the time, and probably still is, the best place for mathematics in the country, if not the world. Tell that to the Americans! I managed to persuade the authorities to allow me to change to music, much against their judgement. After my degree I went to the careers office. I said I was interested in sound, music and acoustics, to which they recommended a career in either deaf aids or depth sounding. So I applied for a job at Decca Records. The boss was at Lords watching cricket the day I had my appointment, but his deputy told me they didn’t employ women in the recording studio.

This is the guy who turned down The Beatles, no doubt.

No doubt. I knew the BBC had a Research Department, and I knew that there was such a thing as the Radiophonic Workshop, that was credited with doing fantastic sounds for broadcast programs. People weren’t generally allowed to work at the Workshop for more than three months at a time. They thought it would send people crazy.

To begin with Delia thought she had found her own private paradise where she could combine her interests in the theory and perception of sound; modes and tunings, and the communication of moods using purely electronic sources. Within a matter of months she had created her recording of Ron Grainer’s Doctor Who theme, one of the most famous and instantly recognisable TV themes ever. On first hearing it Grainer was tickled pink: “Did I really write this?” he asked. “Most of it,” replied Derbyshire.

Talking about limited resources, I think one thing that appeals to us both about Peter Zinovieff‘s EMS VCS3 machine is that it’s really quite a limited selection of resources, but it’s got infinite possibilities of interconnection and patching.

Peter Zinovieff was doing the most interesting things. He didn’t claim to be a musician, he didn’t claim to be a composer. But imagine one of these beautiful London townhouses… the drawing room on the first floor was totally crammed with telephone relay equipment, where he was working on his random sequencers.

Probabilistic stuff.

And I thought, golly, this is the way things should go. And, I think, it was my belief in Peter that encouraged Victoria [Zinovieff] to really believe in him. Because he was Russian aristocracy, and the circle in which he mingled regarded him as a dilettante. That was a beautifully interesting time, everything was mechanical. This was before voltage control. So we worked together for a couple of years.

Yes, as Unit Delta Plus?

Yes.

You set up the organisation to bring electronic music more to the fore in advertising and TV and film music?

We wanted to bring it to the public, yes.

How about these ‘happenings’ you were involved with? I know there was an event in 1966 at the Chalk Farm Roundhouse called Rave or Rave On, and Paul McCartney was top of the bill…

Oh yes, there were two of the Beatles there, Paul and George. It was basically a concert of pre-recorded electronic music.

Thus began what is still referred to as the Golden Age of the Radiophonic Workshop. Initially set up as a service department for Radio Drama, it had always been run by someone with a drama background. Derbyshire was the first person there with any higher music qualifications, but as she wasn’t supposed to be doing music, much of her early work remained anonymous under the umbrella credit ‘special sound by BBC Radiophonic Workshop’.

Before long the Workshop’s TV output had overtaken work produced specifically for radio broadcast. Derbyshire was called upon to do music for drama and documentary programmes set in the distant past, the unseen future or deep in the human psyche – in fact any area where an orchestra would be out of place. Science, arts and educational programmes also benefited from her abstract style. Her work with Barry Bermange on the four Inventions for Radio is perhaps the best illustration of Delia’s intuitive way with soundscaping.

Derbyshire soon gained a reputation for successfully tackling the impossible. When asked to “make some TV title music using only animal sounds” – much thought and ingenuity resulted in Great Zoos of the World. Delia always managed to soften her purist mathematical approach with a sensitive interpretative touch – ‘very sexy’ said Michael Bakewell on first hearing her electronic music for Cyprian Queen.

Derbyshire also worked with the composers Sir Peter Maxwell Davies, Roberto Gerhard (on his 1965 Prix Italia winning ‘Anger of Achilles’), and Ianni Christou, doing sound treatments of their orchestral music. She was also assistant to Luciano Berio at the 1962 Dartington summer school.

On being told at the Workshop that her music was ‘too lascivious for 11 year olds’ and ‘too sophisticated for the BBC2 audience’, Delia found other fields where the directors were less inhibited – film, theatre, ‘happenings’ and original electronic music events, as well as pop music and avant garde psychedelia. To do this she encouraged the establishment of Unit Delta Plus, Kaleidophon and Electrophon, private electronic music studios where she worked with Peter Zinovieff [composer and inventor], David Vorhaus and Brian Hodgson.

Delia’s works from the 60s and 70s continue to be used on radio and TV some 30 years later, and her music has given her legendary status with releases in Sweden and Japan. She is also constantly mentioned, credited and covered by bands from Add n to (x) and Sonic Boom to Aphex Twin and The Chemical Brothers.

A recent Guardian article called her ‘the unsung heroine of British electronic music’, probably because of the way her infectious enthusiasm subtly cross-pollinated the minds of many creative people. She had exploratory encounters with Paul McCartney, Karlheinz Stockhausen, George Martin, Pink Floyd, Brian Jones, Anthony Newley, Ringo Starr and Harry Nilsson.

A complete list of her works has yet to be compiled, but amongst other things she has mentioned doing: Special works and soundtracks for the Brighton Festival, the City of London Festival, Yoko Ono’s “Wrapping Event”, the award winning “Circle of Light”, music for Peter Hall’s “Work is a 4 Letter Word” starring Cilla Black, The White Noise LP “An Electric Storm”, special sound and music for plays at the RSC Stratford, Greenwich Theatre, Hampstead Theatre and the Chalk Farm Roundhouse.

White Noise - A must own

Derbyshire was also involved in several of the earliest electronic music events in England, including shows at the Watermill Theatre, Nr Newbury, the Chalk Farm Roundhouse [with Paul McCartney], The Royal Festival Hall and the first electronic music fashion show!

Work from Delia’s engagement at the BBC has also been published on numerous Radiophonic Workshop and Doctor Who LPs and CDs.

By the mid 1970s Derbyshire was disillusioned by the apparent future of electronic music and withdrew from the medium. In the musical dark ages to follow, she worked in a bookshop, an art gallery and a museum. In the mid 90s she noticed a change in the air and became aware of a return to the musical values she held so dear.

Delia passed away in Northampton, England, on July 3rd 2001.

Shortly before Delia died, she wrote the following: “Working with people like Sonic Boom on pure electronic music has re-invigorated me. He is from a later generation but has always had an affinity with the music of the 60s. One of our first points of contact – the visionary work of Peter Zinovieff, has touched us both, and has been an inspiration. Now without the constraints of doing ‘applied music’, my mind can fly free and pick-up where I left off.”

Auto-Tune: Why Pop Music Sounds Perfect

February 11, 2009

If you haven’t been listening to pop radio in the past few months, you’ve missed the rise of two seemingly opposing trends. In a medium in which mediocre singing has never been a bar to entry, a lot of pop vocals suddenly sound great.

Autotuner brigade

Better than great: note- and pitch-perfect, as if there’s been an unspoken tightening of standards at record labels or an evolutionary leap in the development of vocal cords. At the other extreme are a few hip-hop singers who also hit their notes but with a precision so exaggerated that on first listen, their songs sound comically artificial, like a chorus of ’50s robots singing Motown.

The force behind both trends is an ingenious plug-in called Auto-Tune, a downloadable studio trick that can take a vocal and instantly nudge it onto the proper note or move it to the correct pitch. It’s like Photoshop for the human voice. Auto-Tune doesn’t make it possible for just anyone to sing like a pro, but used as its creator intended, it can transform a wavering performance into something technically flawless. “Right now, if you listen to pop, everything is in perfect pitch, perfect time and perfect tune,” says producer Rick Rubin. “That’s how ubiquitous Auto-Tune is.” (Download TIME’s Auto-Tune Podcast from iTunes)

Auto-Tune’s inventor is a man named Andy Hildebrand, who worked for years interpreting seismic data for the oil industry. Using a mathematical formula called autocorrelation, Hildebrand would send sound waves into the ground and record their reflections, providing an accurate map of potential drill sites. It’s a technique that saves oil companies lots of money and allowed Hildebrand to retire at 40. He was debating the next chapter of his life at a dinner party when a guest challenged him to invent a box that would allow her to sing in tune. After he tinkered with autocorrelation for a few months, Auto-Tune was born in late 1996.

Almost immediately, studio engineers adopted it as a trade secret to fix flubbed notes, saving them the expense and hassle of having to redo sessions. The first time common ears heard Auto-Tune was on the immensely irritating 1998 Cher hit “Believe.” In the first verse, when Cher sings “I can’t break through” as though she’s standing behind an electric fan, that’s Auto-Tune–but it’s not the way Hildebrand meant it to be used.

The program’s retune speed, which adjusts the singer’s voice, can be set from zero to 400. “If you set it to 10, that means that the output pitch will get halfway to the target pitch in 10 milliseconds,” says Hildebrand. “But if you let that parameter go to zero, it finds the nearest note and changes the output pitch instantaneously”–eliminating the natural transition between notes and making the singer sound jumpy and automated. “I never figured anyone in their right mind would want to do that,” he says.

Like other trends spawned by Cher, the creative abuse of Auto-Tune quickly went out of fashion, although it continued to be an indispensable, if inaudible, part of the engineer’s toolbox. But in 2003, T-Pain (Faheem Najm), a little-known rapper and singer, accidentally stumbled onto the Cher effect while Auto-Tuning some of his vocals. “It just worked for my voice,” says T-Pain in his natural Tallahassee drawl. “And there wasn’t anyone else doing it.”

Steinberg Cubase RC application for the Apple iPod Touch / iPhone!!!

February 6, 2009

cubaserc-storypic

Available as a free iPod application from the iTunes store (starting sometime during the second-quarter, 2009) Steinberg Cubase RC, or Remote Control, will provide wireless control over many basic functions of the new Cubase 5.

The most obviously useful of these is the comprehensive transport controls. You’ll be able to use your iPhone / iPod Touch’s touch screen to remotely record, stop and playback your track — very useful if you’re recording yourself in the live room and your studio intern has called in sick again (a call you fielded with your iPhone; neat!). There are even controls for marker placement, metronome settings and toggling cycle mode on/off.

For live performance, Cubase RC provides complete access over the Cubase Arranger function in Cubase 5. Trigger playback stems, assemble playlists, jump between sections of a project and text all at the same time!

Cubase RC is compatible with both Mac OS X and Windows initialized iPods and iPhones, giving you remote control over Cubase 5 regardless of what operating system it’s running on.

Artist Profile: DJ Daedelus

February 4, 2009

57125-500-343
Alfred Darlington isn’t your average cookie-cutter musician. From how he looks (early Victorian Dandism), to how he makes music, to how he expresses himself and views the world, his is a very individual, a ‘bespoke’ outlook.

Long established (and sometimes derided) as an electronic producer with whimsical, jazz-like sensibilities, Daedelus often plays with genre, from the summery samba sweep of 2006′s Denies the Day’s Demise to the bubbly avant-hop of 2003′s Rethinking the Weather and 2004′s Exquisite Corpse (all on Mush records). In 2008, he’s tackling rave music — specifically the “zoo rave” and hardcore/pre-jungle styles of the early ’90s — which he calls “my little temple, my little altar.”

“I’ve been collecting these records since ’92, when I was too young to know what I was putting my hands on, but I just liked the sound. And I’ve been buying them ever since,” says Daedelus. “Finally, I feel comfortable enough after this many years of releasing records to make a stab at it.”

The result is a pair of impressive releases. In January, influential L.A. imprint Alpha Pup issued Live at Low End Theory, a document of a Daedelus’ performance at the popular Los Angeles event. Throughout the 60-minute disc, Daedelus tweaks a Monome, a small MIDI device designed by engineers Brian Crabtree and Kelli Cain, that’s connected via USB cable to a MacBook running a Cycling ’74 Max/MSP software program with the OSC protocol. The setup allows him to chop up dozens of tracks from his decade-long discography, remixing them into a furiously imaginative set.

Alfred was born in Santa Monica in 1977 to an artist mother and psychologist father. Musical from very early on, as a child he was classically and jazz-trained in a number of instruments, but his interests were broad and varied – less a prodigy than a renaissance boy whose obsessions ranged from Greek legend to the mountains of Wales. As a 15 year old he finally persuaded his parents to take him to the Principality. Whilst in a YMCA in London he flipped the radio dial, found a pirate radio station and taped some UK rave and hardcore. “It was my first ‘Eureka!’ moment in music,” he says.

Back in the US he joined local rock bands, jazz bands and ska bands, which he enjoyed but felt limited by,too. At home he was listening to Warp, Ninja and your harder electronic stuff. He started DJing out the more leftfield side of drum and bass and making his own rudimentary productions. They were meant to be drum & bass but they kept turning out different and from his outsider’s experiments his own style was born. He chose the name Daedelus as he had a childhood obsession with invention, and what was he doing, after all, if not tinkering and fiddling and experimenting like the “gentleman inventors” of old?

In 1999 he started DJing on Dublab.com for his “Entropy Sessions” and began dropping in his own early demo productions. Carlos Nino (of ammoncontact) had the show after him and usually pushed Alfred out the studio as quickly as possible as he was not so into Daedelus’ confrontational DJ style, but when he heard a tranquil Daedelus production he took, in typical Nino style, Daedelus under his considerable wing around the LA scene. Nino placed Daedelus tracks on two influential compilations and then persuaded Plug Research to release his debut album, “Invention” in 2002, Remixers included Madlib, who later took Daedelus’ accordian parts and used them on the Madvillain record, closely followed by his “The Household” EP on Prefuse 73’s Eastern Developments label.

In 2003, he was booked to play a show in San Diego by Brian Crabtree and Peter Siegerstrong and they asked him to test out an early prototype of the Monome box. “It’s a Non-traditional electronic instrument,” Daedelus explains. “Basically it allows for massive improvisation.” Since then Daedelus has continued to use this revolutionary box, bringing much genuine liveness to the sometimes static world of performed electronic/dance music.

In 2003 he did “The Weather” album with Busdriver and Radioinactive and the remix album “Rethinking the Weather” on Mush records (home of cLOUDDEAD, also on Big Dada/Ninja Tune). 2004 saw the release of “Of Snowdonia” on Plug Research, the album with which Daedelus says he first “felt true artistic confidence, finding a true voice. I was finally in the right zone.”

There was certainly no let up in his creativity. Also in 2004 he released the concept album “A Gent Agent” on tiny German label Laboratory Instinct. The 2005 album “Exquisite Corpse” on Mush album featured the likes of TTC, Mike Ladd, MF Doom. Ninja signed Daedelus for UK/Europe (a relationship which has reached its full expression on “Love To Make Music To,” his first album for the label worldwide and put together with the help of their team). In 2006 “Denies the Days Demise” came out, a record showcasing his love of Brazilian music. Last year he released his first live album, “Live At the Low End Theory,” and “The Fairweather Friends EP”. Later this year will see the release of his collaboration with his wife, Laura Darling, as Long Lost!

And while his reputation has grown internationally, his place in the LA scene has also solidified. The musician that many of the hottest names in the city turn to for everything from bass clarinet licks to advice on obscure electronics, Daedelus has worked extensively with Taz from Sa-Ra, the pair of them opening for the likes of DJ Assault, Justice and Two Live Crew as well as appearing in Erykah Badu’s most recent video.

As for “Love To Make Music To,” Daedelus says that this album is “the imaginary memory of a time that never was! It’s my drug/love record, harking back to that time in the YMCA in London, when I first heard rave…”

Daedelusis a flagship user for the Monome, a small MIDI device designed by engineers Brian Crabtree and Kelli Cain, that’s connected via USB cable to a MacBook running a Cycling ‘74 Max/MSP software program with the OSC protocol. The setup allows him to chop up dozens of tracks from his decade-long discography, remixing them into a furiously imaginative set.

Sound Technology Glossary

February 4, 2009

knobs2

A rather comprehensive list of terms associatted with recording and MIDI.

If there is something you would like to know which isn’t on here. please feel free to get in touch.

-Dolphin Team

AC: Alternating Current.
A/D CONVERTER: Circuit for converting analogue waveforms into a series of equally spaced numerical values represented by binary numbers. The more ‘bits’ a converter has, the greater the resolution of the sampling process.
ACTIVE: Describes a circuit containing transistors, ICs, tubes and other devices, that require power to operate and are capable of amplification.
ADDITIVE SYNTHESIS: A system for generating waveforms or sounds by combining basic waveforms or sampled sounds prior to further processing with filters and envelope shapers.
ADSR: Envelope generator with Attack, Sustain, Decay and Release parameters. This is a simple type of envelope generator and was first used on early analogue synthesizers. This form of envelope generator continues to be popular on modern instruments. See Decay for more details.
ACTIVE SENSING: A system used to verify that a MIDI connection is working, that involves the sending device sending frequent short messages to the receiving device to reassure it that all is well. If these active sensing messages stop for any reason,the receiving device will recognise a fault condition and switch off all notes. Not all MIDI devices support active sensing.
AFL: After Fade listen; a system used within mixing consoles to allow specific signals to be monitored at the level set by their fader of level control knob. Aux sends are generally monitored AFL rather than PFL (see PFL).
AFTERTOUCH: A means of generating a control signal based on how much pressure is applied to the keys of a MIDI keyboard. Most instruments that support this do not have independent pressure sensing for all keys, but rather detect the overall pressure by means of a sensing strip running beneath the keys. Aftertouch may be used to control such functions as vibrato depth, filter brightness, loudness and so on.
ALGORITHM: A computer program designed to perform a specific task. In the context of effects units, algorithms usually describe a software building block designed to create a specific effect or combination of effects.
ALIASING: When an analogue signal is sampled for conversion into a digital data stream, the sampling frequency must be at least twice that of the highest frequency component of the input signal. If this rule is disobeyed, the sampling process becomes ambiguous as there are insufficient points to define each cycle of the waveform, resulting in enharmonic frequencies being added to the audible signal.
AMBIENCE: The result of sound reflections in a confined space being added to the original sound. Ambience may also be created electronically by some digital reverb units. The main difference between ambience and reverberation is that ambience doesn’t have the characteristic long delay time of reverberation – the reflections mainly give the sound a sense of space.
AMP: (Ampere) Unit of electrical current.
AMPLIFIER: Device that increases the level of an electrical signal.
AMPLITUDE: Another word for level. Can refer to sound levels or electrical signal levels.
ANALOGUE: Circuitry that uses a continually changing voltage or current to represent a signal. The origin of the term is that the electrical signal can be thought of as being ‘analogous’ to the original signal.
ANALOGUE SYNTHESIS: A system for synthesizing sounds by means of analogue circuitry, usually by filtering simple repeating waveforms. ATTENUATE: To make lower in level.
ANTI-ALIASING FILTER: Filter used to limit the frequency range of an analogue signal prior to A/D conversion so that the maximum frequency does not exceed half the sampling rate.
APPLICATION: Alternative term for computer program.
ARPEGGIATOR: Device (or software), that allows a MIDI instrument to sequence around any notes currently being played. Most arpeggiators also allows the sound to be sequenced over several octaves, so that holding down a simple chord can result in an impressive repeating sequence of notes.
ASCII: American Standard Code for Information Interchange. A standard code for representing computer keyboard characters by binary data.
ATTACK: The time taken for a sound to achieve maximum amplitude. Drums have a fast attack, whereas bowed strings have a slow attack. In compressors and gates, the attack time equates to how quickly the processor can change its gain.
AUDIO FREQUENCY: Signals in the human audio range: nominally 20Hz to 20kHz.
AUTOLOCATOR: Feature of a tape machine or other recording device that enables specific locations to be stored, then at some later time, these locations within the recording may be recalled. For example, you may store the start of a verse as a locate point so that you can get the tape machine to wind back the start of the verse after you’ve recorded an overdub.
AUX: Control on a mixing console designed to route a proportion of the channel signal to the effects or cue mix outputs (Aux Send).
AUX SEND: Physical output from a mixer Aux Send buss.
AUX RETURN: Mixer inputs used to add effects to the mix.
AZIMUTH: Alignment coordinate of a tape head which references the head gap to the true vertical relative to the tape path.
BACKUP: A safety copy of software or other digital data.
BAND PASS FILTER (BPF): Filter that removes or attenuates frequencies above and below the frequency at which it is set. Frequencies within the band are emphasised. Bandpass filters are often used in synthesizers as tone shaping elements.
BALANCE: This word has several meanings in recording. It may refer to the relative levels of the left and right channels of a stereo recording, or it may be used to describe the relative levels of the various instruments and voices within a mix.
BALANCED WIRING: Wiring system which uses two out-of-phase conductors and a common screen to reduce the effect of interference. For balancing to be effective, both the sending and receiving device must have balanced output and input stages respectively.
BANDPASS: A filter that passes frequencies only between specific upper and lower limits.
BANDWIDTH: A means of specifying the range of frequencies passed by an electronic circuit such as an amplifier, mixer or filter. The frequency range is usually measured at the points where the level drops by 3dB relative to the maximum.
BETA VERSION: Software which is not fully tested and may include bugs.
BIAS: High frequency signal used in analogue recording to improve the accuracy of the recorded signal and to drive the erase head. Bias is generated by a bias oscillator.
BINARY: Counting system based on only two states – 1s and 0s.
BIOS: Part of a computer operating system held on ROM rather than on disk. This handles basic routines such as accessing the disk drive.
BIT: Binary digit, which may either be 1 or 0.
BOOST/CUT CONTROL: A single control which allows the range of frequencies passing through a filter to be either amplified or attenuated. The centre position is usually the ‘flat’ or ‘no effect’ position.
BOUNCING: The process of mixing two or more recorded tracks together and re-recording these onto another track.
BPM: Beats Per Minute.
BREATH CONTROLLER: Device that converts breath pressure into MIDI controller data.
BUFFER: Circuit designed to isolate the output of a source device from loading effects due to the input impedance of the destination device.
BUFFER MEMORY: Temporary RAM memory used in some computer operations, sometimes to prevent a break in the data stream when the computer is interrupted to perform another task.
BUG: Slang term for software fault or equipment design problem.
BUSS: A common electrical signal path along which signals may travel. In a mixer, there are several busses carrying the stereo mix, the groups, the PFL signal, the aux sends and so on. Power supplies are also fed along busses.
BYTE: A piece of digital data comprising eight bits.
CARDIOID: Meaning heart shaped, describes the polar response of a unidirectional microphone.
CD-R: A recordable type of Compact Disc that can only be recorded once – it cannot be erased and reused.
CD-R BURNER: A device capable of recording data onto blank CD-R discs.
CV: Control Voltage used to control the pitch of an oscillator or filter frequency in an analogue synthesizer. Most analogue synthesizers follow a one volt per octave convention, though there are exceptions. To use a pre-MIDI analogue synthesizer under MIDI control, a MIDI to CV converter is required.
CAPACITANCE: Property of an electrical component able to store electrostatic charge.
CAPACITOR: Electrical component exhibiting capacitance. Capacitor microphones are often abbreviated to capacitors.
CAPACITOR MICROPHONE: Microphone that operates on the principle of measuring the change in electrical charge across a capacitor where one of the electrodes is a thin conductive membrane that flexes in response to sound pressure.
CHANNEL: A single strip of controls in a mixing console relating to either a single input or a pair of main/monitor inputs.
CHANNEL: In the context of MIDI, Channel refers to one of 16 possible data channel over which MIDI data may be sent. The organisation of data by channels means that up to 16 different MIDI instruments or parts may be addressed using a single cable.
CHANNEL: In the context of mixing consoles, a channel is a single strip of controls relating to one input.
CHASE: Term describing the process whereby a slave device attempts to synchronise itself with a master device. In the context of a MIDI sequence, Chase may also involve chasing events – looking back to earlier positions in the song to see if there are any program change or other events that need to be acted upon.
CHIP: Integrated circuit.
CHORD: Three or more different musical notes played at the same time.
CHORUS: Effect created by doubling a signal and adding delay and pitch modulation.
CHROMATIC: A scale of pitches rising in semitone steps.
CLICK TRACK: Metronome pulse which assists musicians in playing in time.
CLIPPING: Severe form of distortion which occurs when a signal attempts to exceed the maximum level which a piece of equipment can handle.
CLONE: Exact duplicate. Often refers to digital copies of digital tapes.
COMMON MODE REJECTION: A measure of how well a balanced circuit rejects a signal that is common to both inputs.
COMPANDER: Encode decode device that compresses a signal while encoding it, then expands it when decoding it.
COMPRESSOR: Device designed to reduce the dynamic range of audio signals by reducing the level of high signals or by increasing the level of low signals.
COMPUTER: A device for the storing and processing of digital data.
CONDUCTOR: Material that provides a low resistance path for electrical current.
CONSOLE: Alternative term for mixer.
CONTACT ENHANCER: Compound designed to increase the electrical conductivity of electrical contacts such as plugs, sockets and edge connectors.
CONTINUOUS CONTROLLER: Type of MIDI message used to translate continuous change, such as from a pedal, wheel or breath control device.
COPY PROTECTION: Method used by software manufacturers to prevent unauthorised copying.
CRASH: Slang term relating to malfunction of computer program.
CUT AND PASTE EDITING: The ability to copy or move sections of a recording to new locations.
CUTOFF FREQUENCY: The frequency above or below which attenuation begins in a filter circuit.
CYCLE: One complete vibration of a sound source or its electrical equivalent. One cycle per second is expressed as 1Hertz (Hz).
CV: Control voltage used in analogue synthesizers, to control oscillator or filter frequency.
DAMPING: In the context of reverberation, damping refers to the rate at which the reverberant energy is absorbed by the various surfaces in the environment.
DAISY CHAIN: Term used to describe serial electrical connection between devices or modules.
DAT: Digital Audio Tape. The commonly used DAT machines are more correctly known as R-DAT because they use a rotating head similar to a video recorder. Digital recorders using fixed or stationary heads (such as DCC) are known as S-DAT machines.
DATA: Information stored and used by a computer.
DATA COMPRESSION: A system used to reduce the amount of data needed to represent an audio signal, usually by discarding audio information that is being masked by more prominent sounds.
dB: deciBel. Unit used to express the relative levels of two electrical voltages, powers or sounds.
dBm: Variation on dB referenced to 0dB = 1mW into 600Ohms.
dBv: Variation on dB referenced to 0dB = 0.775 volts.
dBV: Variation on dB referenced to 0dB = 1 volt.
dB/Octave: A means of measuring the slope of a filter. The more dBs per octave, the sharper the filter slope.
DATA COMPRESSION: A system for reducing the amount of data stored by a digital system. Most audio data compression systems are so-called lossy systems as some of the original signal is discarded based on psychoacoustic principles designed to ensure that only components which cannot be heard are lost.
DC: Direct Current.
DCC: Stationary head digital recorder format developed by Philips. Uses a data compression system to reduce the amount of data that needs to be stored.
dbx: A commercial encode/decode tape noise reduction system that compresses the signal during recording and expands it by an identical amount on playback.
DCO: Digitally Controlled Oscillator.
DDL: Digital Delay Line.

S/PDIF — Acronym for “Sony/Philips Digital Inter Face”. [ Also sometimes referred to by its common "standards" title of IEC958 (type-2). It also conforms with the EIAJ standard of CP-340 (type-2), now renumbered to CP-1201 ].
The S/PDIF digital data format is very similar to the professional AES-EBU standard although it uses different electrical characteristics. The system normally carries 16 or 20-bit data, although it can accommodate 24-bits of audio data per channel. Extra information can also be carried along side the audio such as track start flags, source identification information, and timing data.
The electrical interface is unbalanced and normally employs phono connectors. The source impedance of 75 Ohms and high signal frequencies (0.1 to 6MHz) require good quality 75-Ohm co-axial (RF) cable to operate reliably. Also, as the source amplitude of the data signal is only 0.5V peak-to-peak this restricts the transmission distance to short cable runs of up to about 10 metres.
An optical version of the interface is also available known as “TOSLink” which transmits the same data signals as the electrical IEC958. This is achieved with an LED transmitter and an opto-sensor as the receiver. High quality optical interfaces offer several advantages in terms of galvanic isolation and freedom from electro-magnetic interference, but cheap fibre-optic cables suffer from restricted bandwidths and high dispersion which result in severe timing instability and data errors.

STEREO: two-channel system feeding left and right loudspeakers.
STICKY SHED SYNDROME: A problem affecting some brands of analogue tape after a long time in storage. A breakdown of the binder causes the oxide to shed, and the tape tends to adhere to the tape heads and guides when played. A short term cure can be affected by baking the affected tape for several hours at 50 degrees C.
STRIPE: To record time code onto one track of a multitrack tape machine.
SQUARE WAVE: A symmetrical rectangular waveform. Square waves contain a series of odd harmonics.
SAWTOOTH WAVE: So called because it resembles the teeth of a saw, this waveform contains both odd and even harmonics.
SUB BASS: Frequencies below the range of typical monitor loudspeakers. Some define sub-bass as frequencies that can be felt rather than heard.
SUBCODE: Hidden data within the CD and DAT format that includes such information as the absolute time location, number of tracks, total running time and so on.
SUBTRACTIVE SYNTHESIS: The process of creating a new sound by filtering and shaping a raw, harmonically complex waveform.
SURGE: Sudden increase in mains voltage.
SUSTAIN: Part of the ADSR envelope which determines the level to which the sound will settle if a key is held down. Once the key is released, the sound decays at a rate set by the Release parameter. Also refers to a guitar’s ability to hold notes which decay very slowly.
SWEET SPOT: The optimum position for a microphone, or for a listener relative to monitor loudspeakers.
SWITCHING POWER SUPPLY: A type of power supply that uses a high frequency oscillator prior to the transformer so that a smaller, lighter transformer may be used. These power supplies are commonly used in computers and some synthesizer modules.
SYNC: A system for making two or more pieces of equipment run in synchronism with each other.
SYNTHESIZER: Electronic musical instrument designed to create a wide range of sounds, both imitative and abstract.
TAPE HEAD: The part of a tape machine that transfers magnetic energy to the tape during recording, or reads it during playback.
TEMPO: The rate of the ‘beat’ of a piece of music measured in beats per minute.
TEST TONE: steady, fixed level tone recorded onto a multitrack or stereo recording to act as a reference when matching levels.
THD: Total Harmonic Distortion.
THRU: MIDI connector which passes on the signal received at the MIDI in socket.
TIMBRE: The tonal ‘colour’ of a sound.
TOSLINK: See “S/PDIF”.
TRACK: The term dates back to multitrack tape where the tracks are physical stripes of recorded material, located side by side along the length of the tape.
TRACKING: The system whereby one device follows another. Tracking is often discussed in the context of MIDI guitar synthesizers or controllers where the MIDI output attempts to track the pitch of the guitar strings.
TRANSPARENCY: Subjective term used to describe audio quality where the high frequency detail is clear and individual sounds are easy to identify and separate.
TREMOLO: Modulation of the amplitude of a sound using an LFO.
TRANSDUCER: A device for converting one form of energy to another. A microphone is a good example of a transducer as it converts mechanical energy to electrical energy.
TRANSPOSE: To shift a musical signal by a fixed number of semitones.
TRIANGLE WAVE: Symmetrical triangular shaped wave containing odd harmonics only, but with a lower harmonic content than the square wave.
TRS JACK: Stereo type jack with Tip, Ring and Sleeve connections.
TRUSS ROD: A metal bar within a guitar neck which is tensioned so as to counteract the tendency for the neck to bend under the tension of the strings.
UNBALANCED: A 2-wire electrical signal connection where the inner or hot or +ve (positive) conductor is usually surrounded by the cold or -ve (negative) conductor, which forms a screen against electrical interference.
UNISON: To play the same melody using two or more different instruments or voices.
USB: (Universal Serial Buss) A high-speed serial communications protocol which allows (theoretically) up to 127 hot-swappable peripherals to be connected in daisy-chain fashion. USB devices can be unplugged/plugged in without having to reboot your computer. Popular on modern PCs and associayted computer peripherals (printers, scanners etc) but also adopted by Apple on their iMac and blue G3 machines onwards.
VALVE: Vacuum tube amplification component, also known as a tube.
VELOCITY: The rate at which a key is depressed. This may be used to control loudness (to simulate the response of instruments such as pianos) or other parameters on later synthesizers.
VOCODER: Signal processor that imposes a changing spectral filter on a sound based on the frequency characteristics of a second sound. By taking the spectral content of a human voice and imposing it on a musical instrument, talking instrument effects can be created.
VOICE: The capacity of a synthesizer to play a single musical note. An instrument capable of playing 16 simultaneous notes is said to be a 16-voice instrument.
VIBRATO: Pitch modulation using an LFO to modulate a VCO.
VU Meter: Meter designed to interpret signal levels in roughly the same way as the human ear, which responds more closely to the average levels of sounds rather than to the peak levels.
WAH PEDAL: Guitar effects device where a bandpass filter is varied in frequency by means of a pedal control.
WATT: Unit of electrical power.
WARMTH: Subjective term used to describe sound where the bass and low mid frequencies have depth and where the high frequencies are smooth sounding rather than being aggressive or fatiguing. Warm sounding tube equipment may also exhibit some of the aspects of compression.
WAVEFORM: A graphic representation of the way in which a sound wave or electrical wave varies with time.
WHITE NOISE: A random signal with an energy distribution that produces the same amount of noise power per Hz.
WORD CLOCK: The precise and accurate timing of digital audio samples is critical to the correct operation of interconnected digital audio equipment. The ‘metronome’ that governs sample timing is called the Word Clock (sometimes conjoined to ‘Wordclock’, or abbreviated to ‘Wclk’). However, word clock does more than merely beat time; it also identifies the start and end of each digital word or sample, and which samples belong to the left or right channels. Digital interfaces such as the AES-EBU and S/PDIF embody clock signals within the data stream, but it is often necessary to convey a discrete word clock between equipment as a square wave signal running at the sampling rate. Dedicated word clock inputs and outputs on digital equipment generally use BNC connectors (the kind of terminals commonly used for video).
WRITE: To save data to a digital storage medium, such as a hard drive.
XG: Yamaha’s alternative to Roland’s GS system for enhancing the General MIDI protocol so as to provide additional banks of patches and further editing facilities.
XLR: Type of connector commonly used to carry balanced audio signals including the feeds from microphones.
Y-Lead: Lead split so that one source can feed two destinations. Y leads may also be used in console insert points in which case a stereo jack plug at one end of the lead id split into two monos at the other.
ZENITH: Parameter of tape head alignment relating to whether or not the head is perpendicular to the tape path, and aligned so as to be in the same plane.
ZERO CROSSING POINT: The point at which a signal waveform crosses from being positive to negative or vice versa.
ZIPPER NOISE: Audible steps that occur when a parameter is being varied in a digital audio processor

Music Industry Inside: Ringtones can cost more than the actual song!

January 30, 2009

ringtones

Juniper Research released a report in 2005  stating that the ringtone industry could bloat to $9.3 billion (USD) by 2009.

Lets take a look at Britian’s  No1 in the charts right now to get a feel of where things are headed.  Introducing  Lady GaGa

Just Dance (Download)

Price: $0.99
Remix "Just Dance Feat. Colby O'Donis"

Hmmm so it appears the standard pricing is that the ‘actual song’ is nearly three times the cost to purchase than a snippet in ringtone format.

” While the downloads of mobile ringtones and realtones will comprise the bulk of revenues ($4.8 billion), the market for full-track downloads is expected to increase from just $20 million in 2004 to nearly $1.8 billion in 2009, while ring-back tones – already generating substantial revenues in Asia – should be worth $2.7 billion worldwide by the end of the decade”

And depending which source you read a staggering $14 Billion by the end of 2011 (ezinearticles.com)

Still waiting to find the results of that particular forcast however there is no deneying the effect that the music industry is in a strange position right now where the ringtone can cost more than the actual song.

Music sales worldwide fell by about 7 percent last year as another sizable jump in digital sales failed to make up for a deepening decline in the compact disc market, according to John Kennedy, chief executive of the industry’s main international trade group. The IHT reports.

Revenue from music sold over the Internet, via mobile phones and in other digital forms, rose by 25 percent last year, to $3.7 billion, the International Federation of the Phonographic Industry said in a report set for publication Friday. Digital sales accounted for 20 percent of the industry’s revenue, up from 15 percent a year earlier.

Meanwhile, growth in downloads from online music stores like Apple’s iTunes has slowed. … That is hastening the music industry’s push to develop new business models for digital music.

Major record labels have joined with Nokia, the maker of cellphones, to provide free, unlimited music downloads in Britain. …

“The industry has shifted to Plan B,” said Mark Mulligan, an analyst at Forrester Research. “The record companies have realized that the only way they can fight free is with free itself.”

“Mobile Music Sales Will Reach $3.2 Billion by 2012 But Analysts Say ‘Tracks Must Be Free’, The music industry has got to be prepared to give music away for free”according to analysts Screen Digest.

But full-track downloads will only make up half of that, with the rest still coming from things like ringtones. The report warns “paying for music is progressively becoming a niche activity as the value of recorded music is already in steep, possibly terminal, decline”.

In 2000, U.S. consumers bought 785.1 million albums; last year, they bought 588.2 million (a figure that includes both CDs and downloaded albums), according to Nielsen SoundScan. In 2000, the ten top-selling albums in the U.S. sold a combined 60 million copies; in 2006, the top ten sold just 25 million. Digital sales are growing — fans bought 582 million digital singles last year, up sixty-five percent from 2005, and purchased $600 million worth of ringtones — but the new revenue sources aren’t making up for the shortfall.
