The music demixing machine: toward real-time remixing of classical music
(Springer, 2023-04-06) Cabañas-Molero, Pablo Antonio; Muñoz-Montoro, Antonio Jesús; Vera-Candeas, Pedro; Ranilla, José
Classical music, unlike popular music, is usually recorded live with close microphone techniques. For this reason, isolated tracks are not available to create the final mixture/stream, and so the mixing process requires greater effort. Source separation methods are a potential solution to this problem. However, current algorithms are not fast enough to yield real-time separation in professional setups with dozens of microphones and sources. In this paper, we propose a fast approach consisting of a panning-based multichannel non-negative matrix factorization model to separate classical music. We tested the system on real professional recordings, where we were able to reach real-time with very low latency and promising quality.
