I have some old demos I did many years ago on 4-track tape. I've digitized them but now I'd like to bring them into a DAW (FL Studio) and rework them. (Processing the audio, adding new parts over the top etc.)
Because they were on tape, the timing varies a bit so the recordings can't just be overlaid with new digital tracks.
Obviously FL does time-stretching / pitch-shifting. But it seems to just be from one overall speed to another.
So are there any tools that help "quantize" an existing, slightly irregular recording?
What I'm looking for is something where I'd be able to import an entire track as a WAV. Then place it against a timing track, adding markers at crucial points so the software can warp the audio-recording to fit the timing-track, stretching / shrinking / pitch-shifting each section as appropriate.
I assume something like this must exist, but I don't know what to call it.
