recorded at wrong sample rate. music is faster and higher pitched! HELP!

i recorded a session the other day in pro tools at 48 khz. the problem was, the clock was set to 44.1 khz and now i have 44.1 khz files that play back at 48 khz (so they sound sped up - faster and higher in pitch). i can bump the clock back to 44.1 khz (with a 48 khz session) and play it back at the desired speed and pitch, but when i bounce the tracks into a stereo file, i still get the higher tempo file (the bounce happens in the sound card and the clock is external).

is there a way to turn a 48 khz aiff into a 44.1 without resampling?

if all else fails, i'll just play back tracks into a DAT after I mix them, then import them into pro tools from the DAT, but there's got to be an easier way, doesn't there?

This doesn't address your problem, but in the future you might just want to record in 44.1 24bit. I've been reading alot about this lately, and it seems the concensus of at least alot of pros is to just record in the destination format 44.1 and avoid the dither.

i normally would, but the intended destination format wasn't 44.1khz, it was 48khz (for film). dithering won't be an issue.

we were recording at the lower speed, but the file ended up being at the high speed (hence the increase in tempo and pitch). so, even though the click track was set to 60 bpm (for example), we were playing to a click track around 55 bpm.

so, i have two steps to make in order to get the cues to be the correct length.

1. get the sample rate to be 44.1 (so it sounds as it was originally recorded).

2. time compress all of the cues to compensate for the ratio ([44.1/48]:1)

its a huge difference, especially over a 2 minute film cue, that needs to be corrected. if i had the budget, i'd rerecord, but i don't.

I feel your pain, but I'm sure that doesn't help.

monster, I am not sure if you can do that in PT or not. I know in most apps the only way around that is to resample. I will get a file shipped in for a project that is at 44.1 and the sent file is at 48 and the only way I know around it is to resample. I will usually send the file to Wavelab or SoundForge for that process though as they run the resample edit much faster then other apps.

I know that is not much good news but I am pretty sure that is the only solution.

Maybe el musico will catch this thread this tommorrow and he might know something more as he uses PT and is much more familier with it.
