 This is relevant for machine learning models that today often process raw (time domain) audio and assembling a batch on the fly. It is therefore important to load the audio as fast as possible. At the same time a library should ideally support a variety of uncompressed and compressed audio formats and also is capable of loading only chunks of audio (seeking). The latter is especially important for models that cannot easily work with samples of variable length (convnets).
