Algorithm info: Mono-to-stereo model trained by me for use with MSST. Takes a mono recording and separates Left from Right, panning instruments roughly where they'd sit in a real stereo mix. First model of its kind; more to come.
Made for mono pre-70s records. That's what it was trained on. Don't expect anything on modern material or songs that are already stereo.
Alpha / very WIP. It can be unstable. Shared mainly to show that Mel-Band RoFormer can be trained for something other than separation.
