Recorded in 48, DAT 44.1 >PC What is the best way to deal with these files?

[paulrennix]

I was sent a dozen tapes that were supposed to be recorded 44.1

they were actually recorded in 48

So, I had tapes recorded in 48, played back at 44.1 during the transfer...

Is there an easy way to make these "right" using Soundforge or Waves?

I know there is in CEP and Wavelab. I suspect SF has the same functionality.  You want to change the WAV header to the approripate SR.  In CEP it's called "Adjust Sample Rate".  The actual sample rate conversion process is called "Convert Sample Rate".  You'll know when you have it correct, b/c changing the WAV header is basically instantaneous.  Converting the sample rate will take at least a few minutes.

CDWav will also do the conversion.  After you chop up the file and go to save it will give you the options for output type and then the sample rate in drop down menu's.

Paul.  Do it right and retransfer.  Why resample if you don't need to?

Changing the WAV header to reflect the proper sample rate isn't resampling.  There's no processing happening on the data, it's simply a change in the header info.

I'm confussed how you played at 44 if the dats were 48    do you mean that you had the sample rate in wavelab etc at 44 instead of 48?  I would re transfer is it was me.

Header-Schmeader.  I would still re-transfer.  I am weird like that though.

well, opened in steinberg waves

clicked on 44.1
changed to 48
opened in cdwave
trackedhanks
saved
sounds perfect

its all 1s and zeros anyway. the only thing that makes it 48 as opposed to 44.1 is the header...

thanks all!

Edit to add:  glad its sorted, Paul.  Not sure which Waves plug-in you used, but as long as it didn't take time to actually resample, it probably just changed the header info.

That would do it, yeah - different SR setting in the recording s/w than the actual bitstream.

Really, there's no reason to go through the hassle of re-transferring.  Changing the WAV header sample rate just tells the playback device at what sample rate to play the data - in this case, replacing the incorrect information (44.1k) with the proper information (48k).  Changing the header info doesn't change the data in any way.  Try it:

[1]  Open a 44.1k file
[2]  Change the header to 48k and save
[3]  Open the newly saved 48k file
[4]  Change the header back to 44.1k and save
[5]  Compare the original 44.1k and the newly saved 44.1k file

They're identical.  Re-transferring is a waste of time, IMO.
