Hi John,

I think Corey is on to it. Try this:

Use a short file that you know is good for test purposes. It can be short - a minute or so. Copy the data in the corrupt file, as before, but this time paste it to the end of the test file. Save it to a new file name and look to see if the new file size reflects the combined data. If it does, you may be OK. Now, just delete the test portion of the new file, save it, and see if the file size seems right.

Best,
Gary

Hi John,

No one has mentioned Metadata yet. If the PCM data isn't corrupt
(Wavelab doesn't think so) then you may have a Metadata issue which all
software uses to read and launch a file.

Good luck,

Corey
