I have been recording using arecord and aplay this way:
arecord -D default -d 0 -f cd | aplay -f cd -D default &
The problem is that, while this works fine on rhel5, the same is no true
for Fedora 12 using pulseaudio, since I clearly hear some random noise (specially at low volumes).
Maybe this is related to the fact that the arecord process is consuming 15% of my CPU (a quadcore, 2.4MHz). Compared to Audacious 2.2, for instance, playing an mp3 file, which consumes only 4% of the CPU, this is really too much.
I concluded that the problem has to do with recording with pulseaudio active.
I know there are parecord and paplay, but they are just symbolic links to pacat,
and I do not know how to combine them in a similar way.
Therefore, my question is what is the best way of recording with pulseadio, without wasting too much of my CPU and without noise?
Thanks.
