Difference between 32 bit int and 32 bit float in wav

Archived from groups: rec.audio.pro (More info?)

Hi,
where can I find in the header of a .wav-file whether it is 32 bit int
or 32 bit float. Thanks for helping.

I don't think the actual wav file format allows floating point values,
just int pcm. At least, the broadcast wav standard doesn't allow it.

You can find the compression code at 0x06, and for a standard PCM file
it'll be 0x0001. If it's anything else odd (like floating point data),
it will be something else. It should be 0xFFFF for any nonstandard data.
