Core functionality

Librosa is a python package for music and audio analysis. It provides the building blocks necessary to create audio retrieval systems.

Core functionality (loading audio, spectral representations, etc.) is accessible from the top level of the package, while more specialized functionality (beat tracking, visualization, etc.) is organized into submodules.
