hello,
I have been asking that the developers of PD help me by repairing the
wave file read and write objects in the 64-bit environment as the
headers of the PD written files are all messed up, and PD cant read
in wav files without the user having to overide the headers. I am
patient an hopefully something will happen there soon.
In the mean time does anyone know how to repair the header of a wav
file? I tried snd-7 but it cannot open the file. Sox doesnt reconize
the file format. I can play the files written by PD by using:
aplay -f dat test.wav
Thanks for your help!

a test tone with bad headers)

Remove the WAV header in some way (everything up to and including letters
'DATA'). Then use something like this:
sox -t raw -r 48000 -swc2 broken-wave.raw corrected.wav
You can skip the header deletion, but then you get a clock at the
beginning of the corrected WAV (the click may be hearable).

How about replacing the current WAV read/write objects with a wrapper
around the libsndfile routines. This will allow you to read and write
much more than just WAV files, the code works with either endian-ness
and works on 64 bit systems.
libsndfile is already used for file I/O in SuperCollider and I believe
John ffitch (spelling?) is also working on using in Csound.
