As a rather inexperienced Audacity user, I ran into the following problem:
I was not aware of any recording length or file size limitations, so I made from radio a timed recording, lasting almost 7 hours. Audacity version was 1.3 Beta.
I thought that I process the recording later, so I saved it in WAV format. No complaints from Audacity, none at all. I checked the saved file size from Windows Explorer; it said 4 258 569 KB, which seemed about right.
Later I tried to open the file. Opening seemed to happen very quickly: Audacity had opened only 6 minutes 13 seconds from the beginning of the file!
Digging a little I learned that WAV files cannot be longer than 4 GB. Audacity had saved the total contents of the recording, more than 4 GB, but stored as file size in the file header only the amount by which the actual file size exceeded 4 GB. And so Audacity – or any other sound program – will open only the first few minutes of the file. For most purposes, the file is corrupt.
Any ideas of how to salvage the contents of this file, or at least most of it?
I have plenty of space and the file system is NTFS. Win 7 32 bit, now Audacity 2.0.6
