aubio is a library for audio labelling. Its features include
segmenting a sound file before each of its attacks, performing
pitch detection, tapping the beat and producing midi streams from
live audio. The name aubio comes from 'audio' with a typo:
several transcription errors are likely to be found in the
results too.

jack-audio-connection-kit and ffmpeg are optional dependencies.

The python bindings are built if numpy is available and the python3
ones are built if numpy3 is available: if both versions of python
are present in the system, the aubio and aubiocut python scripts
will use python3.
