11 aubio is a library to label music and sounds. It listens to audio signals and
12 attempts to detect events. For instance, when a drum is hit, at which frequency
13 is a note, or at what tempo is a rhythmic melody.
15 Its features include segmenting a sound file before each of its attacks,
16 performing pitch detection, tapping the beat and producing midi streams from
19 aubio provide several algorithms and routines, including:
21 - several onset detection methods
22 - different pitch detection methods
23 - tempo tracking and beat detection
24 - MFCC (mel-frequency cepstrum coefficients)
25 - FFT and phase vocoder
27 - digital filters (low pass, high pass, and more)
29 - transient/steady-state separation
30 - sound file read and write access
31 - various mathematics utilities for music applications
33 The name aubio comes from _audio_ with a typo: some errors are likely to be
39 A python module for aubio is provided. For more information on how to use it,
40 please see the file [`python/README.md`](python/README.md) and the
41 [manual](https://aubio.org/manual/latest/) .
46 The python module comes with the following command line tools:
48 - `aubio` extracts informations from sound files
49 - `aubiocut` slices sound files at onset or beat timestamps
51 Additional command line tools are included along with the library:
53 - `aubioonset` outputs the time stamp of detected note onsets
54 - `aubiopitch` attempts to identify a fundamental frequency, or pitch, for
55 each frame of the input sound
56 - `aubiomfcc` computes Mel-frequency Cepstrum Coefficients
57 - `aubiotrack` outputs the time stamp of detected beats
58 - `aubionotes` emits midi-like notes, with an onset, a pitch, and a duration
59 - `aubioquiet` extracts quiet and loud regions
