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:
- several onset detection methods
- different pitch detection methods
- tempo tracking and beat detection
- MFCC (mel-frequency cepstrum coefficients)
- FFT and phase vocoder
- up/down-sampling
- digital filters (low pass, high pass, and more)
- spectral filtering
- transient/steady-state separation
- sound file read and write access
- various mathematics utilities for music applications
The name aubio comes from _audio_ with a typo: some errors are likely to be
found in the results.
Python module
-------------
A python module for aubio is provided. For more information on how to use it,
please see the file [`python/README.md`](python/README.md) and the
[manual](https://aubio.org/manual/latest/) .
Examples tools
--------------
The python module comes with the following command line tools:
- `aubio` extracts informations from sound files
- `aubiocut` slices sound files at onset or beat timestamps
Additional command line tools are included along with the library:
- `aubioonset` outputs the time stamp of detected note onsets
- `aubiopitch` attempts to identify a fundamental frequency, or pitch, for
each frame of the input sound
- `aubiomfcc` computes Mel-frequency Cepstrum Coefficients
- `aubiotrack` outputs the time stamp of detected beats
- `aubionotes` emits midi-like notes, with an onset, a pitch, and a duration
- `aubioquiet` extracts quiet and loud regions
