I know this isn't the highest tech but thought someone might know the

Using an mp3 player with voice recorder, I was reading a book, hit
pause to get something, and didn't return to recording. I fell asleep
and forgot to hit save. The battery must have run down and did some
kind of autosave. The file is 8 megs but in using Adobe Audition to
edit it, there
is no wav to display. Does anyone know how to extract that data or
fix the file?
There is a possibility that the only thing wrong with the file
is that the software never got a chance to update the audio length
in the header. Some software looks at the header for the length,
and if it is listed as zero, will not bother to look further for
the data.
I have a program called 'wavelength' that fixes the length entry
in a wav header. It's compiled for Linux, but it comes with source
code.
Aside from that, try taking the first 44 bytes from another wav
file, and add that to the beginning of your corrupt file. You may
have to run 'wavelength' again, or hex edit the header. If this
works, you can use an audio editor to cut out the old header.
e wav header is in no way limited to 44 bytes, but a very large
percentage of wav files out there do conform to this.
You could also import the data as raw into a suitable editor,
providing the sample rate etc. by hand. You will still have to
edit out the old header.
Failing all else, send me the file. I'll fix it for you.
