There are three types of audio sources that can be injected into the OtsAV audio pipeline: media files (MP3, Wave, and Ots files), audio CD tracks, and Live Input signal. These audio sources can be injected two ways: through the decks when playing either a media file or an audio CD track, and through the Live Input feature when routing external audio through a soundcard's input functionality.
