Aubio is a library for audio labelling. Features include onset detection (the complex task of labelling the beginning of notes and other sound events), silence detection (an easier but very useful task) and pitch detection (the estimation of the fundamental frequency of the sound).
The aim is to add these automatic labelling features to other audio softwares. Functions can be used offline in sound editors and software samplers, or online in audio effects and virtual instruments.
Aubio is still in an alpha state. More to come soon, suggestions and feedback welcome.
The name Aubio comes from 'audio' with a typo. It is likely to have many transcription errors in the results too!
This code has been written by Paul Brossier . It is based on recent techniques developed at Queen Mary College, University of London.
