aubio has been built to be used by audio developpers to add high level feature extraction to their softwares. Because these tasks are difficult, we thought it was important to gather them in a dedicated library. To increase the fun, we have made these algorithms work in a causal or almost causal way, so as to be used in real time applications with as low delay as possible.


aubio is written in C. The current version of aubio depends on:

  • libsndfile, the sound file acces from Erik de Castro Lopo
  • libsamplerate, the resampling library, also from Erik
  • FFTW, the Fastest Fourier Transform of the West, from the Steven G. Johnson et al. at MIT

The following dependencies are optional:

  • JACK, Jack Audio Connection Kit, for real-time audio input/output on linux and macosx
  • ALSA, for midi output from aubionotes
  • Swig, to build modules for languages supported by SWIG (perl, java and many more)
  • Python, to build and use the python scripts provided in the python directory.

Note: on a debian system, the required dependencies can be obtained using:

# apt-get build-dep aubio
