I saw that a few folks are getting corrupted headers in their wave files and having a struggle with the existing utilities trying to fix the problem. So I cobbled together a wave header repair utility this last weekend that may help... 'cause I hate to see good music go to waste
But it's a butt ugly command line program... if you want pretty, try next door.
Since it's mostly "universal" C coding, I was able to get it to compile on both Linux and Winders... don't own a Mac, sorry.
Beat the hell out of it and it seems to be working, but I'd be surprised if there wasn't some bugs still down in the cracks... so for sure, only use it on a backup copy.
Here's a sample output where it successfully repaired a wave file that had nothing but zeroes in the entire header and a partially truncated audio data sample (about as bad as it get's)...# ./fixwav junk.wav
Existing header data. Look for the words 'RIFF', 'WAVE', 'fmt',
or 'data' to see if this is even a somewhat valid WAVE header:
00000000: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................
00000010: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................
00000020: 00 00 00 00 00 00 00 00 00 00 00 00 ............

Found incorrect number of audio samples. This means that either
the new WAVE header data is incorrect, or the audio samples
in the existing file were clobbered. Do you wish to add silent
audio samples to the end of the file?
WARNING: this will modify the existing file. [y/n] y
Header repair is required!
Overwrite the existing file? [y/n] y
File repair successful
As you see, you need to know a little about the file... the number of bits, the samples per second, and the number of mics... while that might stump a n00b, I don't think you'll have any problem.
One caveat... it assumes you're feeding it a "normal" wave file... i.e. only a single data "Subchunk"... if it ain't such an animal... or if it simply has junk data appended to it (there's some dumb ass programs that add ID3 tags like that), it's gonna hose up.
anyway, they're attached below... enjoy... and remember... you got it free
