Preset and Parameter Handling
- Preset/Parameter slots
- To enhance the workflow the two Preset/Parameter slots, A and B, can be loaded with two full set of parameters at the same time. Apart from saving each preset, a “Global Preset” containing both the A and B settings, and the position of the “Morphing Slider”, can be saved.

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.
These voice transformation algorithms have already been used, with great success, in international and French cinema productions. (Farinelli, Vatel, Tirésia, Les amours d’Astrée and Céladon)
Source (Trax Transformer)
With the Spectral Envelope complex remapping of the actual spectrum envelope, according to a freely definable curve, can be performed.

Target (Trax Transformer)
Target, provide a range of options for the transformation of the source material. In voice mode, a range of vocal types/ranges are available, and on top of that, parameters such as gender, age and breath can be used as well. For all types of material, pitch, expression and formant are provided as well.
Spectral Envelope (Transformer)
Up to eight channels of simultaneous processing for multichannel surround configuration is provided. The processing can be disengaged on any of the channels leaving the material unprocessed, bypassing the original sound.
When operating on a multi-channel bus all, up to eight in total, channels are processed by default, though the processing can be disengaged for any number of channels leaving the material unprocessed and bypassing the original sound.
By doing this in combination with serial instances the material on any number of channels can be processed with individual settings.

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 nonlinear, the sound morphing is nonlinear as well, offering a way to create a wide range of new exciting and unusual sound effects.
Source Filter – Enhanced Sound Filtering
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.
