part of sonic seminars - spring 2012

20/21/22.04.2012 – A hands-on look at some exotic techniques for sound generation and processing, by Chris Jeffs.

This seminar will present a wide spectrum of lesser known and somehow exotic sound generation and processing techniques. A short presentation and explanation will be provided for each technique, along with sample patches provided for each participant to hack as they choose. These are some of the techniques we will see: physical modeling, distortion, altered harmonic distributions, analogue emulation, phase distortion, dynamic waveshaping, algorithmic waveform generation, and spectral processing techniques using the Fast Fourier Transform.

Time schedule:
Session #01
  • Distortion.
  • Algorithmic waveform generation.
  • Dynamic waveshaping.
Session #02
  • Dynamic Stochastic Synthesis: Gendy.
  • Audio buffer read/write modulation.
  • Phase distortion.
  • Altered harmonic distributions.
  • Physical modelling.
  • Sound granulation.
Session #03
  • Analogue emulation.
  • Spectral processing: Fast Fourier Transform.
  • Sonic textures.
  • Sound effects.
Level: beginners / intermediate
Language: English
Instructor: Chris Jeffs

Chris Jeffs was born in the UK and nowadays lives in Berlin. Originally a trombone player, he progressed to making and releasing electronic music, touring extensively since 1994 as a live artist and DJ, with 13 singles and 5 albums published on Rephlex, most prominently under the name Cylob. He turned to creating his own programs as a way of making his sound more distinctive. His granular synthesis and visual animation software “Particularity” won joint first prize in the LOMUS 2010 competition. Recent activity has focused on freelance iPhone development, in addition to programming for interactive installations and performances.
