Ok, so I have a strange problem that appeared after I reinstalled everything on my PC after the HDD pooped one day. I managed to reset my system to its old standards, FRAPS and Camtasia Studio 8.3 set up. I reconfigured everything to the way it was before everything went down, but now there's this little issue and I can't seem to fix it no matter what I do.
Now, first things first, my speakers and mic have their sample rate programmed to 48khz or 48000Hz. The issue I have though disregards the 16-bit and 24-bit depths my speakers support (by the way, when I say speakers, I'm talking of headphones, my system classifies it as such).
Now, there's my DV-camera (Toshiba Camileo P10 1080p) that I always use for facecams. It always records 30fps, at 48khz audio sample rate.
But here comes the funny bit. Normally the gameplay and the facecam synchronize rather well, and I noticed a desyncing (facecam usually hurries) after about 20 minutes, but it's nothing bad when its audio is muted). However, now it hurries almost 1 minute after the point where it's synced up properly. And it gets progressively worse. Even though the sample rates are the same, they don't sync up like before.
Now here are some of the things I tried.
1) I recorded my mic with Audacity, which exported at 44.1khz (44100Hz) for some reason, but it syncs up perfectly with the camera's footage (which is 48khz) but then the gameplay goes off, and I made sure to sync it properly.
2) Converted both the gameplay and facecam to matching sample rates, but I get the exact same result as always. I even did a test where I used the original (48khz) facecam and the converted (44.1khz) facecam files, and they both synced up, and showed the exact same sync drift with the gameplay.
3) I changed both mic and speaker sample rate to 44.1khz, but it exhibited the same result as always. I know if you set the mic or speaker sample rate differently, then the gameplay's mic goes off-sync, but this is not the case.
4) Tried to speed up camera's audio so that it syncs up, but even a 1% shift causes it to rush ahead after a while.
5) Tried to manually edit the audio malfunction, but something odder shows up. Even though the audio waveforms "match" or "sync up", they still sound off-sync. Potentially.
I've spent at least 20 hours looking into this bug, or whatever this is, and it still baffles me. I'm using exact same settings/drivers as before, but this buggy-bug shows up. Anyone have any ideas other than the above ones? Feedback/suggestions much appreciated!
