10 aubio is a library to label music and sounds. It listens to audio signals and
11 attempts to detect events. For instance, when a drum is hit, at which frequency
12 is a note, or at what tempo is a rhythmic melody.
14 Its features include segmenting a sound file before each of its attacks,
15 performing pitch detection, tapping the beat and producing midi streams from
18 aubio provide several algorithms and routines, including:
20 - several onset detection methods
21 - different pitch detection methods
22 - tempo tracking and beat detection
23 - MFCC (mel-frequency cepstrum coefficients)
24 - FFT and phase vocoder
26 - digital filters (low pass, high pass, and more)
28 - transient/steady-state separation
29 - sound file and audio devices read and write access
30 - various mathematics utilities for music applications
32 The name aubio comes from _audio_ with a typo: some errors are likely to be
38 A python module to access the library functions is also provided. Please see
39 the file [`python/README.md`](python/README.md) for more information on how to
45 A few simple command line tools are included along with the library:
47 - `aubioonset` outputs the time stamp of detected note onsets
48 - `aubiopitch` attempts to identify a fundamental frequency, or pitch, for
49 each frame of the input sound
50 - `aubiomfcc` computes Mel-frequency Cepstrum Coefficients
51 - `aubiotrack` outputs the time stamp of detected beats
52 - `aubionotes` emits midi-like notes, with an onset, a pitch, and a duration
53 - `aubioquiet` extracts quiet and loud regions
55 Additionally, the python module comes with the following script:
57 - `aubiocut` slices sound files at onset or beat timestamps

80 Credits and Publications
81 ------------------------
83 This library gathers music signal processing algorithms designed at the Centre
84 for Digital Music and elsewhere. This software project was developed along the
85 research I did at the Centre for Digital Music, Queen Mary, University of
86 London. Most of this C code was written by myself, starting from published
87 papers and existing code. The header files of each algorithm contains brief
88 descriptions and references to the corresponding papers.
90 Special thanks go Juan Pablo Bello, Chris Duxbury, Samer Abdallah, Alain de
91 Cheveigne for their help and publications. Also many thanks to Miguel Ramirez
92 and Nicolas Wack for their bug fixing.
94 Substantial informations about the algorithms and their evaluation are gathered
