A: It depends on how much synthesis power do you need. If you are using
deferred-time only, you can use ANY computer. Regarding real-time, if you
only use audio, you need at least a Pentium 133 MHz (which can handle up
to 50 oscillators in real-time at 44100 Hz). A Pentium II 400 can give you
more than 200 oscillators at 44100 Hz. However actual polyphony depends by
several factors such as sampling rate, computer motherboard, RAM type, cache
memory size and the buffer size you set in the command line call (flag -b).
If you are using animated Graphics, I recommend at least a Pentium II 500
with a 3D accelerated video card supporting OpenGL in hardware. Notice that,
up to the recent past, OpenGL was supported only by a little group of
professional 3D accelerated video cards. At present time, however, it seems
that OpenGL is supported by almost all new consumer video cards (but you
have to be informed about it before buying the video card). However, a good
(and expensive) video card is higly recommended to achieve interesting results
at a decent frame rate. At present time (January 2002) probably nVidia cards
are the best solution (a geForce ||| with 64 MB of video RAM would be very
good, even if a professional card can provide acceleration of a more complete
set of OpenGL API). However I can obtain nice results even with my cheap
laptop mounting a chip S3 Savage/IX with only 8 MB of video RAM.
If you are using both animated graphics and realtime sound synthesis, even
the computer speed could make sensible difference. At present time (January
2002) the optimal solution would be a 2GHz Pentium4. I've never tried Athlon
processors, so I can't express judjement.
For realtime audio, also the type of audio card can increase the performance.
Unfortunately, it seems that professional audio cards don't allow the minimum
latency with CsoundAV, because of the limited support of DirectX, so I suggest
to use a cheap SBlive! (BtW: I haven't tried SBlive Audigy yet, but the specs
suggest to have a better audio quality than normal SBlive!). When ASIO support
will be implemented, probably professional audio cards will give the best.
