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.
‘Could you repeat that please?’
Godfried Toussaint writes this neat paper on transcribing and generating African music rhythms via Euclidean geometry. Euclidean geometry is taking a set of simple, known elements and producing new elements from these. Applied to music he devises algorithms to generate permutated rhythms.
Euclid was a great Greek Mathematician from Alexandria.

‘The objects use the analogue means of materials and mechanical movements to manipulate sound.
Four objects create the effects of Tremolo, Reverb, Delay and Mouth Modulation.
Sound Revival aims to create a greater understanding of how sound effects are generated and gives visual identity to something unseen as a result of digital technology. Objectifying these effects brings intrigue back into the DJ performance and brings listeners and performer together.’
