Jim, if you record with PCM Wave, the recorder needs ten megs per
minute. If I want to know, how much space is required, while recording
with a certain bitrate, I divide it by two. When one records with 64
KBPS for instance, one would need a little less then 32 megs per hour.
If one records with 128 KBPS, one needs a little less then 64 megs per
hour. This formular gives a relatively rough estimate, but it is
accurate enough for me, because one always gets a little more time, than
the calculation suggests.

And now a little question. Which file is bigger, a 64 KBPS stereo file
or a 64 KBPS monaural one?

Answer: Which box is heavier, a one Kilogram plastic box or one made of
iron also weighing one Kilogram?
