=== Music source separation and instrument recognition ===
Music source separation is about separating original signals from a mixture [[audio signal]]. Instrument recognition is about identifying the instruments involved in music. Various MIR systems have been developed that can separate music into its component tracks without access to the master copy. In this way, for example, karaoke tracks can be created from normal music tracks, though the process is not yet perfect owing to vocals occupying some of the same [[frequency]] space as the other instruments.
