Hi All...

While trying to write a paper on my website to prove Linux can be an option
for HDR, I wish to know the latencies ALSA architecture achieves on various
soundcards to compare them with Windows drivers for the same cards. If some
of you have measured such latency, please let me know (thru this mailing
list is ok).

I pardon you to steal some of your time, but it is for the sake of free
software vs buggy cute unprofessionnal sequencers/HDR.

By latency, I mean the time needed to echo a signal on a card's input to the
output, without any further treatment. Please let me know if there are
additionnal parameters....

Also, (I don't know anything about Linux kernel drivers, pardon me) I wanted
to know if this latency could be improved with RTLinux... Which is free
(there is not a single free real-time add-on for Windows NT, IMHO).

Thanks a lot for your precious time.

Benjamin GOLINVAUX
