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.
