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/) . 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 Documentation ------------- - [manual](https://aubio.org/manual/latest/), generated with sphinx - [developer documentation](https://aubio.org/doc/latest/), generated with Doxygen The latest version of the documentation can be found at: https://aubio.org/documentation Build Instructions ------------------ aubio compiles on Linux, Mac OS X, Windows, Cygwin, and iOS. To compile aubio, you should be able to simply run: make To compile the python module: ./setup.py build See the [manual](https://aubio.org/manual/latest/) for more information about [installing aubio](https://aubio.org/manual/latest/installing.html).
