aubio is a collection of tools for music and audio analysis.
This package integrates the aubio library with [NumPy] to provide a set of
efficient tools to process and analyse audio signals, including:
- read audio from any media file, including videos and remote streams
- high quality phase vocoder, spectral filterbanks, and linear filters
- Mel-Frequency Cepstrum Coefficients and standard spectral descriptors
- detection of note attacks (onset)
- pitch tracking (fundamental frequency estimation)
- beat detection and tempo tracking
aubio works with both Python 2 and Python 3.

Demos
-----
Some examples are available in the [`python/demos` folder][demos_dir]. Each
script is a command line program which accepts one ore more argument.
**Notes**: installing additional modules is required to run some of the demos.
### Analysis
- `demo_source.py` uses aubio to read audio samples from media files
- `demo_onset_plot.py` detects attacks in a sound file and plots the results
using [matplotlib]
- `demo_pitch.py` looks for fundamental frequency in a sound file and plots the
results using [matplotlib]
- `demo_spectrogram.py`, `demo_specdesc.py`, `demo_mfcc.py` for spectral
analysis.
### Real-time
- `demo_pyaudio.py` and `demo_tapthebeat.py` use [pyaudio]
- `demo_pysoundcard_play.py`, `demo_pysoundcard.py` use [PySoundCard]
- `demo_alsa.py` uses [pyalsaaudio]
### Others
- `demo_timestretch.py` can change the duration of an input file and write the
new sound to disk,
- `demo_wav2midi.py` detects the notes in a file and uses [mido] to write the
results into a MIDI file
### Example
Use `demo_timestretch_online.py` to slow down `loop.wav`, write the results in
`stretched_loop.wav`:
$ python demo_timestretch_online.py loop.wav stretched_loop.wav 0.92
Built with
----------
The core of aubio is written in C for portability and speed. In addition to
[NumPy], aubio can be optionally built to use one or more of the following
libraries:
- media file reading:
- [ffmpeg] / [avcodec] to decode and read audio from almost any format,
- [libsndfile] to read audio from uncompressed sound files,
- [libsamplerate] to re-sample audio signals,
- [CoreAudio] to read all media formats supported by macOS, iOS, and tvOS.
- hardware acceleration:
- [Atlas] and [Blas], for accelerated vector and matrix computations,
- [fftw3], to compute fast Fourier Transforms of any size,
- [Accelerate] for accelerated FFT and matrix computations (macOS/iOS),
- [Intel IPP], accelerated vector computation and FFT implementation.
