knows that zyn is not RT-safe. he had several conversations with
me at LAC2005 about how to redesign the internals. it works fine at
larger latencies.
Judging from those messages, it seems like it should certainly work at
128 frames, maybe 64. But 32 is insanely low - too low for most sound
hardware. That setting is more appropriate for stress testing the
kernel, than for actual music making.
I beg to differ. Especially because some AD/DA's introduce quite a bit
of additional latency. When i used my cs46xx based card i had to go down
to 32 frames to get an acceptable latency for playing my guitar through
jack-rack. I once measured the roundtrip latency of this card and found
out my AD/DA's added another 4-5ms of latency to the 1.333ms latency
which were caused by the periodsize of 32 frames. And it seems 6ms total
latency was fine for me :)
Well, my point was really that it will depend a lot on the soundcard.
RME can't go below 64 at all. My emu10k1s can do 32 in playback only
mode but need to use 64 for full duplex. Etc...
