Music source separation

Music source separation (MSS), also known as stem separation, demixing, audio source separation or unmixing, is a technique of separating one audio track into multiple audio tracks by targeting mixed material using music information retrieval (MIR). MSS is a branch of signal separation which was established in the mid-1990s as a technology to reconstruct…
