This crate provides safe Rust bindings to [_aubio_](https://github.com/aubio/aubio) C 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.
## Crate features
The following features can be used to customize configuration:
- __bindgen__ Force generate bindings itself instead of use pre-generated (_useful for unsupported archs_)
- __builtin__ Force compile builtin _aubio_ C library
- __pkg-config__ Use _pkg-config_ to find installed libraries
- __shared__ Build shared _aubio_ C-library
- __static__ Build static _aubio_ C-library
- __fftw3__ Enable using _fftw3_ library
- __intelipp__ Enable using _Intel IPP_ library
- __accelerate__ Enable using acceleration framework on _apple_ platforms
- __blas__ Enable using _blas_ library
- __atlas__ Enable using _atlas_ library
- __double__ Enable double presicion of audio sample data
When __pkg-config__ feature is used the installed __aubio__ library will be used if found.
To force build and link builtin version you can use __builtin__ feature.
The features such as __fftw3__, __intelipp__, __accelerate__, __blas__, __atlas__ and __double__ is take an effect only for builtin _aubio_ C library.
