Ircam TRAX

Ircam Trax v3 - The Next Generation Voice and Sonic Processing Tools

Trax is a suite of three processors using advanced technology, developed during many years, by the sound analysis/synthesis team at Ircam. These precision tools provide innovative signal transformation algorithms allowing the user to alter sound characteristics such as: pitch, timbre and duration, using an intuitive user interface.

Transformer - Real-time Voice and Sonic Modelling Processor

Trax Transformer is based on an augmented phase vocoder technology and a cutting edge transformation algorithm, allowing for manipulating characteristic properties of a voice such as gender, age and breath, and on any other sound; expression, formant and pitch.

Source Filter - Enhanced Sound Filtering Processor

Trax Source Filter is based on a signal model decomposing the signal into a time envelope describing the energy/loudness contour of the sound, and a spectral envelope describing the spectral colour of the sound timbre. The energy contour and the spectral colour of the source sound, can be continuously blended with the spectral colour and energy contour of an arbitrary filtrating sound, allowing transformation that extend well beyond the more common source filter morphing effect.

Cross Synthesis - Spectral Envelope Morphing Processor

Trax Cross Synthesis utilizes a phase vocoder (the amplitude and the frequency/phase spectra), to morph the spectral characteristics of two sounds. The amplitude and frequency/phase spectra can be blended continuously and since the features that are used here are strongly non-linear, the sound morphing is non-linear as well, offering a way to create a wide range of new exciting and unusual sound effects.
