This step-by-step how-to will guide you through the process of extracting various features from audio files using the Java Audio Feature Extraction.

How-To

1. Start the application

You can start the Java Feature Extraction application from in a terminal by invoking

Further select the output directory (the directory where the feature-files will be placed) and enter a common basename for the featurefiles. The filenames will be <basename.rp.vec, <basename.rh.vec and <basename.ssd.vec respective.

3. Choose features to extract

Check/uncheck the features-sets you want to extract.

Further select the number of parallel extraction threads and whether you want compressed feature files (saves up to 52% diskspace).
