I have an unusual issue, probably not a common one.
There's a karaoke site where you can find both mono and stereo versions of songs people have performed. I want to take a mono version with someone's vocal and line it up with the stereo version of the track.
The problem is, while it's the same track, for some reason the mono and stereo versions after processing by the site aren't beat-identical. The mono version ends up being slightly shorter than the stereo version. On a 4 minute song, maybe a difference of a second or so but more than enough so that they won't line up exactly. Other people's stereo versions of the song can be matched up beat for beat so it's something to do with how the site processes mono vs stereo.
Is there such a thing as an app that will match up two tracks like this so they're identically in sync?
I tried time-stretching the one with Soundforge and can get close but not close enough. The beat-sync drifts over the course of the track. Slightly ahead in one place, drifting to slightly behind in another, resulting in phasiness. I suppose it could be a desirable effect if that's what you were after but that's not what I'm after. It seems it would have to be an app that senses the beat pulses and matches them up.
