From what I can see....
You have a channel count of 75 and a frame size of 83 bytes. Total frame count is 40430 and the meta data is 2309 bytes. So all up the files size should be around 3357999 bytes ( give or take some sundry bytes ).
The header and meta data looks fine, but the frame data looks to have lost some data and skewed the frame data. This has messed up the frame data completely, but think it's still all there. I'll see if I can nudge it back into alignment.
