So I ripped my TPM Blu-Ray, converted the audio to mono WAVs, then downloaded your PCM track and did the same, and threw the center channel of both into Audacity to swap out the opening theme and…
…they’re not in sync. Which I was very much not expecting - I figured all crawls were probably the same length and the music the same tempo and such, so it would be an easy swap. Turns out that’s not the case.
So I don’t have any kind of an ETA on my “fixed” audio track with a less-shitty-sounding opening theme, unfortunately. That’s going to require more fucking around than I expected.
