Show HN: Transpose Spotify audio and isolate vocals/instruments in realtimehttps://github.com/evanhu1/transposify
Sharing a macOS menu-bar app I made that lets you transpose and separate instrument tracks from Spotify songs in realtime. Uses Rubberband engine pitch shifting with formant preservation to avoid the ogre-like sound of pitching down, and HTDemucs converted to Core ML (NN model) to do live audio separation via sliding audio windows. I think this is the best tool of its kind (lowest latency, highest quality, realtime). It's invaluable for me now with karaoke, practicing singing / piano along with Spotify songs.
