Audio signal processing is a subfield of signal processing that is concerned with the electronic manipulation of audio signals. Audio signals are electronic representations of sound waves—longitudinal waves which travel through air, consisting of compressions and rarefactions. The energy contained in audio signals or sound power level is typically measured in decibels. As audio signals may be represented in either digital or analog format, processing may occur in either domain. Analog processors operate directly on the electrical signal, while digital processors operate mathematically on its digital representation.
SuperCollider is an environment and programming language originally released in 1996 by James McCartney for real-time audio synthesis and algorithmic composition.
The Roland TR-909 Rhythm Composer, commonly known as the 909, is a drum machine introduced by Roland Corporation in 1983, succeeding the TR-808. It was the first Roland drum machine to use samples for some sounds, and the first with MIDI functionality, allowing it to synchronize with other devices. Though a commercial failure, it influenced the development of electronic dance music genres such as techno, house and acid house.
Live coding, sometimes referred to as on-the-fly programming, just in time programming and conversational programming, makes programming an integral part of the running program.
Scott Wilson is a Canadian composer. He studied music and composition in Canada, the U.S., and Germany, and his teachers include Barry Truax, Wolfgang Rihm, Christos Hatzis, Gary Kulesha, Ron Kuivila, Alvin Lucier, Owen Underhill, Neely Bruce and David Gordon Duke. Since 2004 he has lived in Birmingham, UK, where he is Reader in Electronic Music and Director of Birmingham ElectroAcoustic Sound Theatre and the Electroacoustic Studios at the University of Birmingham.
Live electronic music is a form of music that can include traditional electronic sound-generating devices, modified electric musical instruments, hacked sound generating technologies, and computers. Initially the practice developed in reaction to sound-based composition for fixed media such as musique concrète, electronic music and early computer music. Musical improvisation often plays a large role in the performance of this music. The timbres of various sounds may be transformed extensively using devices such as amplifiers, filters, ring modulators and other forms of circuitry. Real-time generation and manipulation of audio using live coding is now commonplace.
Nick Collins is a British academic and computer music composer. From 2006–2013 he lived in Brighton, UK, and ran the music informatics degrees at the University of Sussex. In 2013 he became Reader at the University of Durham.
Alex McLean is a British musician and researcher. He is notable for his key role in developing live coding as a musical practice, including for creating TidalCycles, a live-coding environment that allows programmer musicians to code simply and quickly, and for coining the term Algorave with Nick Collins.
Maya Jane Coles is a British music producer, audio engineer and DJ, born in London. Under her real name, she mostly composes and plays house and techno music, while her alias Nocturnal Sunshine creates darker, more bass-driven productions with a heavy hip-hop and dub influence. She was previously part of an electronic dub duo called She Is Danger with Lena Cullen.
Benoît and the Mandelbrots, named after French American mathematician Benoît Mandelbrot, is a Computer Music band formed in 2009 in Karlsruhe, Germany. They are known for their live coded and Algorave performances, the Digital Arts practice of improvising with programming languages that gradually dissolves the distinction between composer and performer.
An algorave is an event where people dance to music generated from algorithms, often using live coding techniques. Alex McLean of Slub and Nick Collins coined the word "algorave" in 2011, and the first event under such a name was organised in London, UK. It has since become a movement, with algoraves taking place around the world.
Daley Padley, also known as Hot Since 82, is a British DJ, house music producer and DJ Awards winner currently based in Holmfirth, UK. He has been releasing music under the Hot Since 82 moniker since 2012.
Alexandra Cardenas is a Colombian composer and improviser now based in Berlin, who has followed a path from Western classical composition to improvisation and live electronics. Her recent work has included live coding performance, including performances at the forefront of the Algorave scene, she also co-organised a live coding community in Mexico City. At the 2014 Kurukshetra Festival Cardenas was a keynote speaker and hosted a music live coding workshop, the first of its kind in India. Cardenas has been invited to talk about and perform live coding at events such as the Berlin based Transmediale festival and the Ableton sponsored Loop symposium, and held residencies including at Tokyo Wonder Site in Japan and Centre for the Arts in Mexico City.
Vroom Vroom is the second extended play by English singer Charli XCX, released on 26 February 2016 by Vroom Vroom Recordings. It features production work from Scottish producer Sophie.
Ixi lang is a programming language for live coding musical expression. It is taught at diverse levels of musical education and used in Algorave performances. Like many other live coding languages, such TidalCycles, ixi lang is a domain-specific language that embraces simplicity and constraints in design.
Joanne Armitage is a composer, improviser and researcher based in Leeds, England, notable for her practice in live coded music, and research into haptics in music performance. She performs internationally using the SuperCollider language, including as half of live coding duo ALGOBABEZ with Shelly Knotts associated with the Algorave movement. Her music is often performed in a club setting, while embracing error and uncertainty. She is also known as advocate for diversity in music and technology, including through invited workshops. Armitage is a lecturer in Digital Media at the School of Media and Communication, University of Leeds, UK.
Gqom ,(Igqomu ,Gqom tech or Sghubu), is a genre of electronic dance music that emerged in the early 2010s from Durban, South Africa, pioneered largely by music producers DJ Lag, Rudeboyz, Griffit Vigo, Distruction Boyz, Menzi, and Citizen Boy. It was developed from kwaito, a subgenre of house music from South Africa.
Renick Bell is an American musician, programmer, and teacher based in Tokyo, notable as a pioneer of live coded music performance including at algoraves, and for his algorithmic music releases. Bell creates his music using his self-built live coding system Conductive.
Cxema is a Ukrainian organiser of raves in urban spaces in Ukraine and Europe. Its parties have been held several times a year in various post-industrial locations in Kyiv since 2014.
