Ircam Trax May 2026

Use the and Source Filter tools to blend two different sounds into a single hybrid instrument.

: Route a vocal track into the "Filter" input and a rhythmic synth or guitar into the "Source." This imposes the vowel characteristics of the voice onto the instrument’s timbre.

: Adjust the Breathy control to add airiness or a whispered quality to the voice, perfect for intimate or ghostly musical textures. Phase 2: Hybrid Textures (Cross Synthesis)

IRCAM Trax is a powerful suite of three audio processors—, Cross Synthesis , and Source Filter —designed to manipulate the core properties of sound, particularly the human voice. Unlike standard pitch-shifters, it uses advanced phase vocoder technology to separate a sound's "source" (its pitch and breath) from its "filter" (its timbral character), allowing you to change a voice's age, gender, or even species without losing natural quality.
