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 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.
