freebsd sound card performance vs. linux

2002-06-20 Thread Tyler Spivey

ok - i've noticed (on an awe64,
p200 W/ 128 mb of ram),
that recording a sound at 44100 hz stareo:
rec -r 44100 -c 2 file.wav
takes up all my cpu, but under linux, it barely takes up any.
freebsd creates a lot of stuttering/clipping because it's taking up all the CPU 
recording. is this an audio driver bug, or a freebsd bug in general?
tested on 4.5-R.
P.S.: sorry for my bad capatialazation,  I am not very good at that part of english 
yet.

sbc audio driver - buffering

2002-06-15 Thread Tyler Spivey

how would i go about changing the sbc audio driver
so it acts like linux's oss drivers?:
when i use sox to play a file under linux,
i can hit ^c at any time and it stops, bang.
under freebsd, i hit ^c and it waits for a while.
this is probably because of buffering under freebsd, but i do want fast responces to 
the interrupt signal,
so how can i get this under freebsd?
I'm running 4.5-R,
p200, 64 mb of ram, and an awe64 card.
I also have a cmi8738 in the same machine, but i don't like it much.
(aopen aw-848 or something).

signals and applications

2002-06-09 Thread tyler spivey

ok - I hope I can get an answer:
how come (under linux)
i can use my favourite web browser and hit ^c (interrupt)
and it will interrupt any network application,
but under FreeBSD there are some operations that can't be interupted and just wait 
there?

a hopefully simple question

2002-06-08 Thread tyler spivey

Sorry if I'm asking on the wrong list, but
would someone  please write a simple program
to do something like:
beep 200 300
which would make a 200 hz tone  for 300 ms?
or at least tell me where to look for the information i need?
