Patch max

SKataRT is a Max for Live device which brings together concatenative synthesis techniques from Catart and synthesis techniques by mosaicing.


There are two ways of synthesizing sounds: XY and Live Audio modes

The XY mode


The concatenative real-time sound synthesis system SkataRT plays grains (also called units) from a large corpus of segmented and descriptor-analysed sounds according to proximity to a target position in the descriptor space. This can be seen as a content-based extension to granular synthesis providing direct access to specific sound characteristics. The architecture allows, moreover, to mix several sound corpora, which can correspond to different textures (materials) or sound qualities (e.g., concrete vs. abstract).

The Live audio mode


The first idea is to capture a vocal production or an audio sample and modeling it as a parametrizable sound sketch. The vocal or audio signal is described according to its morphological and timbre dimensions. The associated acoustic descriptors are used as input parameters of the corpus-based synthesis system. The process makes it possible to generate a synthetic version of the sketch having some acoustic similarities with the original audio production while allowing to deviate from it and to explore other dimensions.
