librosa.util.example¶

librosa.util.example(key, hq=False)[source]¶

Retrieve the example recording identified by ‘key’.

The first time an example is requested, it will be downloaded from the remote repository over HTTPS. All subsequent requests will use a locally cached copy of the recording.

For a list of examples (and their keys), see librosa.util.list_examples.

By default, local files will be cached in the directory given by pooch.os_cache(‘librosa’). You can override this by setting an environment variable LIBROSA_DATA_DIR prior to importing librosa:

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

Parameters

keystr: The identifier for the track to load
hqbool: If True, return the high-quality version of the recording. If False, return the 22KHz mono version of the recording.

Returns

pathstr: The path to the requested example file
