If you’ve ever learnt an instrument, straining to hear what your favorite musician is playing under the din of other players is probably familiar to you.

Luckily for all the budding Hendrixes, Rachmaninoffs, and Harold Bishops (from the Australian soap opera Neighbours) out there, MIT has a solution. The university’s Computer Science and Artificial Intelligence Laboratory (CSAIL) has created an AI system that can analyze a musical performance and isolate the sounds of specific instruments.
