What kind of latency is expected using 8,16,32 khz?
I am trying to do a realtime stream server, and I am having latency above
>500ms ( I capture the sound using the mic, encode it and send it to the
I am using ALSA system, a SB128 PCI and a 800Mhz P3 . What can I do to lower

I also have a 500 ms latency.
