[Billaboop](http://www.iua.upf.es/~ahazan/BillaBoop/?ref=protein.xyz) is a real-time beat boxing interface, developed by Amaury Hazan at [Music Technology Group](http://www.iua.upf.es/mtg?ref=protein.xyz).

The system lets the user control drum synths, samplers, and effects with their own voice. The project mainly uses techniques of Audio Signal Processing and Machine Learning. Descriptor generation, onset/offset detection, vocal hit segregation, mapping and synthesis are achieved in real-time.

The system uses two methods of machine learning to detect and classify the incoming percussive sounds; supervised and unsupervised modes, when in supervised mode the system refers to pre-recorded samples and attempts to match the sounds of the instrument they represent. When in unsupervised mode the system sorts incoming sound into 3 groups and simulates a form of short-term memory. Although the classification results are less reliable than what is achieved in supervised mode, unsupervised mode gives more robustness when processing noisy data

Example-samples, you can hear the original percussive signals on the right channel and the BillaBoop output stream on the left channel:
