44.1-48k trickery

[darolfm]

Dear folks:
I received a bunch of WAV files that were mis-recorded and have 44.1 tags on them, even though they were recorded at 48k.
This makes it difficult to play back on certain platforms (like mine; DP and/or AudioDesk), which apparently can't force 44.1 files to play back at 48. Of course when I convert them, the pitch and speed remain the same••”wrong.
Is there some kind of workaround for DP or a way I can trick the program into playing back those files at 48k, or some way I can just fix the tags on the files to accurately reflect the sampling rate?
Thanks
Darol

Howdy Darol,

I'm a big fan of your fiddle playing and delighted to offer a little help. Though maybe not the easiest solution.

The sample rate is contained in the resource fork if these files were created on a mac. So you need a utility that will open the resource fork and allow you to edit it. I believe I have done this on the Mac but can't recall if I used Resourcer or Resedit under OS9. It's been awhile.

You'll need a Windows box and a Free Program from Rail Jon Rogut ( http://www.railjonrogut.com/ ) who is a well known sample designer for BFD. Anyway, he has a program called Header Investigator on his site.

From his site, "allow the user to open WAV audio files and display the header information and make changes. The actual audio data is never changed••¦ simply the header information. This is useful if the user has accidentally recorded audio while locked to an external digital clock source so that the header sample rate is a mismatch to the actual sample rate of the data ••“ which causes the sound file to play back at the wrong pitch. By simply changing the sample rate in the header ••“ the WAV files can be corrected without having to retransfer or sample rate convert the file"

others may chime in with a more Mac-like solution. But given the right tool it is a 10 second job. Just edit the sample rate.

Hi

Here is free converter:

I accidentally made files of this sort by having my master clock (Yamaha 02R) set to 48K & the sample rate on the DAW set to 44.1. My work around was to set it back up the way I recorded it, everything would play back fine & I would dump out whatever I needed out analog to another recording source (on its own clock - another DAW or a DAT machine) Probably not as eloquent of a solution as Zeb's, but if you can't his suggestion to work try that.

Good luck!

This in fact would work fine, though an extra trip through less than ideal converters may or may not have an impact.

Does anyone know if the various new sample managment systems, such as AudioFinder or the other one?? allow editing of headers without changing audio? It really is a simple task given an editor that opens the resource fork. Converters that change the audio are "not" the answer.

You can change the header with SoundHack. There's no Intel version, but it may run under Rosetta.

Isn't there something new in DP5.12 that does this conversion?

[darolfm]

you guys are the best. All good suggestions, and I finally just went and downloaded SoundHack, took 5 minutes, then just went in and changed all the file headers (there were 32) to 48k... took another 5 minutes.
THANK YOU!!!!

Yep, you can now do that exact thing inside DP 5.12. There's a checkbox in the convert sample rate dialog box.

Was this mentioned in the latest Gospel from the Gods of MOTU, Cliffo?

I've heard nothing myself, though I generally read said scriptures with one-eyed MOTU passion.
OK, so I skip all the film, SMPTE and sync stuff for fear of retrospective implosion.
