Feature extraction

The file feature_extractor is a python module that uses the open-source library Essentia to extract audio features from an audio file in the path specified in the first parameter and save the features' values to a json file in the path specified in the second parameter.

The module can be imported or executed as a script using one of the following commands python feature_extractor.py <audio_file_path> <extracted_features_file_path> <audio_file_sample_rate> or python3 feature_extractor.py <audio_file_path> <extracted_features_file_path> <audio_file_sample_rate>

A python script is also provided for a batch feature extraction. The script can be executed using one of the following commands: python batch_feature_extractor.py <audio_files_directory> <feature_files_directory> <audio_files_sample_rate> or python3 batch_feature_extractor.py <audio_files_directory> <feature_files_directory> <audio_files_sample_rate>
