Hi,
I'd like to try to setup some 3channel,low-latency audio
beamforming experiments on my linux box with:
mandrake 8.1 kernel-2.4.8
audio card midiman delta1010
I've been lurking and surfing, but I could really use some uptodate
info as far as.
1) what type of latency I can expect from the base configuration,
no kernel patching!
1a)If latency >3ms I'll need to do kernel patch. Are there
patches for 2.4.8 ? who/where would I go?
2) which audio drivers are preferable, OSS installed properly,
and works with ecasound. Is there any advantage to alsa- aside
from the fact that BRUTEFIR assumes its use;-).
3) with Fcpu=400e6 and Fsample=48e3,I get 8333.33 clock ticks per
audio sample. MMX should give a factor of 2 improvement, no?
Perhaps the easiest means to grind about 3 channels of 4Ktaps each
is to buy a 1G pentium?
4) anyone have any experience with BRUTEFIR?
Thanks,
-
Ira
