Subject: Re: [ARSCLIST] corrupted WAV files

Hi Gary and Mickey

I tried copy and paste changing file name of the copy. No luck there.

I tried upsample render then downsample render the upsampled file in
Wavelab. No luck. I only changed the sample rate not the bit rate and
only took it up from 96K to 128K. Going higher for both bit and sample
rates on the whole file, then back down again would take too much time
to process for this test.

I tied saving off to a RAW file, then open (import special audio file)
using Wavelab. No luck there. But when I tried importing the corrupted
WAV file in the same way, then saved that file off to a new version,
that seemed to work. Both corrupted file and new version are the same size.

As this is a consumer project transferring a collection of cassette
tapes that are not an archival level job, I'm very happy with this fix.
I was in a hurry to get home to dinner Friday night and should have
backed up the days work before I started the batch render process.
Lesson learned. Thanks to you both for your input and leading me to a fix!!

Kind Regards,

John Schroth
