4 aubio is a collection of algorithms and tools to label and transform music and
5 sounds. It scans or `listens` to audio signals and attempts to detect musical
6 events. For instance, when a drum is hit, at which frequency is a note, or at
7 what tempo is a rhythmic melody.
9 aubio features include segmenting a sound file before each of its attacks,
10 performing pitch detection, tapping the beat and producing midi streams from
16 aubio provides several algorithms and routines, including:
18 - several onset detection methods
19 - different pitch detection methods
20 - tempo tracking and beat detection
21 - MFCC (mel-frequency cepstrum coefficients)
22 - FFT and phase vocoder
24 - digital filters (low pass, high pass, and more)
26 - transient/steady-state separation
27 - sound file read and write access
28 - various mathematics utilities for music applications
30 The name aubio comes from *audio* with a typo: some errors are likely to be
