the rate at which data arrives over s/pdif *is* the exact sample rate
that the CD is burning at (well, unless you're insane). there is no
need for throttling, pitch control or anything like that. you just
buffer the data on startup to protect against latency glitches,
convert the samples to 16bit, big-endian (the red book standard), and
feed it to the CD recorder. end of story (other than the little
details).
