Re: Audio Capture - File Sizes Double

i haven't noticed this in my code and files. data of that size doesn't fit
in a resource fork. my only guess is that you are recording stereo and are
expecting mono data. or you are recording at 44.1 and are expecting 22050,
etc..
but you're no dummy so i'm sure you thought of that already. then again it
maybe a bug.

try compressing your audio with the exporter. i generally record to file
then immediate compress or export the result. that may solve your problem.
that might be why i haven't noticed. also, i haven't messed with this stuff
since last spring.
