| 1 | −Python aubio module | |
| 2 | −=================== | |
| 3 | − | |
| 4 | −This module wraps the aubio library for Python using the numpy module. | |
| 1 | +aubio | |
| 2 | +===== | |
| 3 | + | |
| 4 | +aubio is a collection of tools for music and audio analysis. | |
| 5 | + | |
| 6 | +This package integrates the aubio library with [NumPy] to provide a set of | |
| 7 | +efficient tools to process and analyse audio signals, including: | |
| 8 | + | |
| 9 | +- read audio from any media file, including videos and remote streams | |
| 10 | +- high quality phase vocoder, spectral filterbanks, and linear filters | |
| 11 | +- Mel-Frequency Cepstrum Coefficients and standard spectral descriptors | |
| 12 | +- detection of note attacks (onset) | |
| 13 | +- pitch tracking (fundamental frequency estimation) | |
| 14 | +- beat detection and tempo tracking | |
| 15 | + | |
| 16 | +aubio works with both Python 2 and Python 3. | |
| 17 | + | |
| 18 | +Built with | |
| 19 | +---------- | |
| 20 | + | |
| 21 | +The core of aubio is written in C for portability and speed. In addition to | |
| 22 | +[NumPy], aubio can be optionally built to use one or more of the following | |
| 23 | +libraries: | |
| 24 | + | |
| 25 | +- media file reading: | |
| 26 | + | |
| 27 | + - [ffmpeg](https://ffmpeg.org) / [avcodec](https://libav.org) to decode and | |
| 28 | + read audio from almost any format, | |
| 29 | + - [libsndfile](http://www.mega-nerd.com/libsndfile/) to read audio from | |
| 30 | + uncompressed sound files, | |
| 31 | + - [libsamplerate](http://www.mega-nerd.com/SRC/) to re-sample audio signals | |
| 32 | + - [CoreAudio](https://developer.apple.com/reference/coreaudio) to read all | |
| 33 | + media files supported natively on macOS, iOS, and tvOS. | |
| 34 | + | |
| 35 | +- hardware acceleration: | |
| 36 | + | |
| 37 | + - [Atlas](http://math-atlas.sourceforge.net/) and | |
| 38 | + [Blas](https://en.wikipedia.org/wiki/Basic_Linear_Algebra_Subprograms), | |
| 39 | + for accelerated vector and matrix computations, | |
| 40 | + - [fftw3](http://fftw.org), to compute fast Fourier Transforms of any size. | |
| 41 | + - [Accelerate](https://developer.apple.com/reference/accelerate) for | |
| 42 | + hardware accelerated FFT and matrix computations on macOs and iOS, | |
| 43 | + - [Intel IPP](https://software.intel.com/en-us/intel-ipp), accelerated | |
| 44 | + vector computation and FFT implementation, | |
