Modifying an audio signal

·   Online

- linear/nonlin. filtering (presence, companding)
- echo / chorus / flanging
- reverberation
- spatial location (azimuth/elevation/range)

·   Event-based

- pitch/duration modification
  (resampling, SOLA, looping, reverse)
- cross-synthesis (LPC/ Fourier domain)

·   Control inputs from:

- explicit interface (sliders, curves)
- analysis extraction from audio streams...
