Zach Lieberman uses Open Frameworks to produce an augmented reality app that lets you sample audio, while generating a 3D visualisation of the sound in AR – in real-time. You can also scan your phone over the waveform to play it back. Just watch the video! Amazing.
The Collidoscope is a prototype for a granular synthesizer/sampler. It features a large display of recorded samples, and interactive controls that show which part of the recorded sample is being played back.
The controls are closely aligned visually so as to be quite clear.
Jeremy Bell has created a tape-scratching device called the ScrubBoard. A tape loop with a tape head-scrubber that you can manipulate with your hands, resulting in a sound akin to scratching a record. There’s other great features. There’s a foot controller to play, stop and reverse playback of the loop. There’s a ‘rocker’ to cut/fade and mix to the tapes other channels. There’s also a record head to do live looping and scratching!
Nice work Jeremy!
Coldcut, in collaboration with Hexstatic, released this audio-visual music collage in 1998
This clip describes the re-production of sound on films, using photographic processes. Sound waves are converted to varying voltages, which affect varying amounts of light, which is then projected and photographed onto the films optical sound track. This is how motion pictures sound tracks have been reproduced in cinemas right up till the 21st Century, hence printed digital sound tracks have become more common.
Here Soviet composer Arseny Avraamov draws wave forms with paint on paper and then films them onto the optical track with amazing results.
Trackers were pioneer software based sequencers very early in the home computer revolution.
