A suite of three processors developed over the years by the sound analysis/synthesis team at IRCAM. Their goal was to provide users with signal transformation algorithms that allow altering of sound characteristics (pitch, timbre and duration) with intuitive high level controls.

Ircam Trax includes three ingenious processors :

• TRAX Transformer based on an augmented phase vocoder technology and a cutting edge transformation algorithm,

• TRAX Cross Synthesis which uses a phase vocoder (the amplitude and the frequency/phase spectra), to morph the spectral characteristics of two sounds,

• and TRAX Source Filter based on a signal model decomposing the signal into a time envelope allowing transformations that extend well beyond the more common source filter morphing effect.
