Hi all,
I'm trying to fine tune the latency for a pd/realtime setup.
The system: Debian/Unstable Intel P4 1.8ghz M-Audio Delta-44 (ice1712 driver) Alsa 0.9 Kernel 2.4.19-pre10 + A. Morton's latest Low-Latency patch
echo 1 > /proc/sys/kernel/lowlatency pd -alsadev hw:0,0 -rt
So far PD's best possible latency is 8 fragments (11 millisec. audio buffer). Below this it is completely unable to keep up.
Is there room for improvement in this setup? (Replacing the sound device is an option... I need as many channels as possible and latency in the 1-3 ms range).
