Interesting, I guess this only works to recover uncompressed wav files where you know the sample frequency and bit depth? Or does it read the wav headers when it finds them or something?
Yes you are correct! My 12 channel mixer (Behringer X12) allows you to plug in a USB disk and record the output. But somebody turned off the mixer while it was recording, which meant that lots of bits of data were written, but the WAV file header was never updated with the size of the file.
So I did another recording to determine the frequency & bit depth, and then opened the dd disk image with those settings. It was pretty obvious from the waveform image which parts of the drive had the recording, and it was perfect.
Interestingly, I got those settings completely wrong at the start, and I could still tell it was music by listening to it, it was just very corrupted sounding!
