/*! # Safe bindings for _aubio_ library [](https://github.com/katyo/aubio-rs) [](https://crates.io/crates/aubio-rs) [](https://docs.rs/aubio-rs) [](https://opensource.org/licenses/GPL-3.0) [](https://github.com/katyo/aubio-rs/actions?query=workflow%3ARust) 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. */ pub(crate) use aubio_sys as ffi; mod fft; mod filterbank; mod log; mod mfcc; mod notes; mod onset; mod pitch; mod pvoc; mod resampler; mod specdesc; mod tempo; mod types; mod utils; mod winfunc; pub mod vec; pub use self::fft::*; pub use self::filterbank::*; pub use self::log::*; pub use self::mfcc::*; pub use self::notes::*; pub use self::onset::*; pub use self::pitch::*; pub use self::pvoc::*; pub use self::resampler::*; pub use self::specdesc::*; pub use self::tempo::*; pub use self::types::*; pub use self::utils::*; pub use self::winfunc::*; /** * Sample data type */ pub type Smpl = ffi::smpl_t; #[macro_export] macro_rules! farr { ($len: expr) => { [0. as $crate::Smpl; $len] }; } #[macro_export] macro_rules! carr { ($len: expr) => { [0. as $crate::Smpl; $len + 2] }; }
