Hey all,I may be a bit late to the party, but I’d be willing to bet that the recording is a multi-track wave file. Most DAWs worth their salt can import them and then (if it doesn’t do it automatically) can split it into tracks.
I have written a script (in Linux, but I could port it if needed) that will take multi track wave, split it into individual tracks, and then apply gain (if needed). If someone is willing to send me a single song sample I’d be willing to give it a go.
