aubio is a library to label music and sounds. It listens to audio signals and attempts to detect events. For instance, when a drum is hit, at which frequency is a note, or at what tempo is a rhythmic melody.
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.
aubio provide several algorithms and routines, including:
The name aubio comes from audio with a typo: some errors are likely to be found in the results.
A python module for aubio is provided. For more information on how to use it,
please see the file python/README.md
and the
manual .
The python module comes with the following command line tools:
