Hi,
I'm sorry I wasn't clear enough: behind the float->int conversion, I'd
like to perform downsampling as well 44KhZ->32, 22, 11, 8 kHz... I
wanted to have the conversion first at the same sampling rate, and then
try to modify that... It appear I'll have no luck :-/ even though
upsampling and int->float conversion works well since I can play back
without difficulties.
thanks,
- Hugues
PS: Sorry about the double posting...

Easy way to convert 32bit float to 16-bit integers:
where sample is the 32-bit float,
short r = round(sample * 0x7FFF);
Don't need a convertor AU for that.
