 The ``dinner_party_background`` file contains features from the CHiME6 training set to use while training, the CHiME6 dev and evaluation sets for validating ambient background, and all DipCo audios for testing ambient background.
 
 The ``no_speech_background`` file contains features from the FMA-medium, FSD50K, and WHAM datasets for training. Any source audio clips less than 6 seconds long were repeated until at least that length. All spectrograms were split over 5 second non-overlapping intervals. The first 25 features were discarded.
