| 1) The Alpha is about 4 times faster at the same clock-speed than a Pentium
| class
| CPU....
Depends on the Pentium. The ~533MHz Alpha EV67 is effectively about twice
as fast as a 500MHz Pentium III Xeon (I got to play with one of Compaq's
prototype "Wildfire" systems yesterday :).
| 2) ATRAC is dedicated hardware. Compare it to the 3D graphics interface in
| your PC. If you didn't have it, you wouldn't be able to sustain 70fps
| with your favourite 3D game.
I've been trying to say this all along, and I never made that analogy.
Thank you.
| ATRAC has changed but not dramaticly after version 3.0. The CPU's in
| PC's have. There will be and there will come a time when CPU's can
| do the ATRAC encoding in real time. Maybee this time has already
| arrived?
The changes are primarilly in the psychoacoustic model. And maybe in two
or three years the average desktop machine will be powerful enough to
handle ATRAC 4 (or whatever) in real time.
| 3) Why is a 128kbit encoding faster than the 384kbit encoding? The
| data that needs to be trown away at 128kbit is 3 times more than at
| 384kbit.
Yep.
