What is source separation?What is source separation?

Source separation refers to the extraction of individual sound sources from a mix of audio signals.
Examples include extracting an instrumental sound from a song, removing MR, and canceling noise.
GSEP (Gaudio source SEParation) is an AI source separation model developed by Gaudio Lab,
which has already proven to be the world's best in various external tests.
