Everything about Music source separation

Audio track separation technique

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 one or more source signals from mixtures of them. The process is generally utilized by music professionals to separate existing recordings for the purposes of enhancing the balance of the mix, remixing, or remastering. There are additional use cases where no multitrack or session files are available for the sound recording, making it necessary to rely on tools that provide stem separation from a single audio file.
