Im trying alBufferData(buffer, AL_FORMAT_STEREO16,data,frames*channels*2,
freq) but when i run it, i get a error:

malloc: *** mmap(size=3143925760) failed (error code=12)
*** error: can't allocate region

and when i debug it, by making it output the frames*channels and
frames*channels*2 to the console, frames*channels is 1571962880 (frames is
5292032 and channels is 4355) and frames*channels*2 is -1151041536.
