Technology for the automatic extraction of digital descriptors from an audio signal, the gathered data represents the principle useful characteristics of the sounds given their classification and comparison.

These technologies let you:

1. Automatically classify sounds.
2. Automatically extract the structure of a piece of music (introduction, chorus, verse, etc.) and automatically calculate a sound summary.
3. Browse musical contents intelligently using an intuitive navigation in audio libraries through the extraction of a large number of high and low level descriptors.
4. Enable recognition of musical excerpts.
