Package echonest :: Package remix :: Module audio :: Class AudioAnalysis

Class AudioAnalysis

This class uses (but does not wrap) pyechonest.track to allow transparent caching of the audio analysis of an audio file.

For example, the following script will display the bars of a track twice:

from echonest import *
a = audio.AudioAnalysis('YOUR_TRACK_ID_HERE')
a.bars
a.bars

The first time a.bars is called, a network request is made of the Echo Nest Analyze API. The second time time a.bars is called, the cached value is returned immediately.

An AudioAnalysis object can be created using an existing ID, as in the example above, or by specifying the audio file to upload in order to create the ID, as in:

a = audio.AudioAnalysis('FULL_PATH_TO_AUDIO_FILE')
