Ircam Trax v3 - The Next Generation Voice and Sonic Processing Tools
Trax is a suite of three processors using advanced technology, developed over 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 a 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 extends 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.
