Example files

librosa includes a small selection of example recordings which are primarily used to demonstrate different functions of the library. Beginning with version 0.8, these examples are automatically retrieved from a remote server upon request. Example recordings are cached locally after the first request, so each file should only be downloaded once.

Downloading files directly

If you want to ensure that example data are always present on your computer, you can clone the data repository directly:

$ git clone /path/to/librosa-data

To ensure that librosa can find the example files, you can set the LIBROSA_DATA_DIR environment variable prior to importing librosa:

$ export LIBROSA_DATA_DIR=/path/to/librosa-data/audio
$ python

or, directly in Python:

>>> import os
>>> os.environ['LIBROSA_DATA_DIR'] = '/path/to/librosa-data/audio'
>>> import librosa

This will bypass any remote network access and use the local copies of the data files directly.

Description of examples

The function librosa.util.list_examples() provides a brief description of each track, and librosa.util.example_info() will provide some metadata and licensing information for a given track.

The following table describes in more detail what the recordings are, and how they are mainly used in the documentation. Key indicates the descriptor used to identify the track when calling librosa.example().
