Real-Time Corpus-Based Concatenative Synthesis with CataRT
Diemo Schwarz, Grégory Beller, Bruno Verbrugghe, Samuel R. Britton · 2006
The concatenative real-time sound synthesis system CataRT plays grains 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. CataRT is implemented as a collection of Max/MSP patches using the FTM library and an SQL database. Segmentation and MPEG-7 descriptors are loaded from SDIF files or generated on-the-fly. The
