CBA-YAAFE-extension

This is an extension for YAAFE (Yet Another Audio Feature Extractor), developed for music detection with the Continuous Frequency Activation feature (CFA) for the Cultural Broadcasting Archive (CBA).

Adaptations

This extension provides the possibility to get the output directly to the commandline for implementing it e.g. in PHP:

$cmd = 'yaafe_cba.py -r 11025 --resample -f "cfa: ContinuousFrequencyActivation" wavefile.wav';

exec( $cmd, $output, $return_value);

New Features

For a list of the new features and a description see: FEATURES.md.
