[−][src]Crate aubio_rs
Safe bindings for aubio library
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.
