I am getting good results from a 500MHz P3. More important than the
processor speed (IMO) is the quality of the audio interface card itself and
how the machine is configured:
1) I am using an RME Hammerfall with external A/D & D/A, along with an
AP2496. Both work fine.
2) Configuration-wise, I've gotten much better results dumping Gnome in
favor of fluxbox, using a dedicated EIDE audio drive with it's own ATA-100
controller, and paying close attention to interrupt settings.
As others will probably report along the way, there are people with @GHz
processors that are getting clicks and pops. Unfortunately, this is a
developing area where we don't know how to tell every person out there how
to get the best results, so as always YMMV.

Subject: Re: [linux-audio-user] clicks and pops
I just realized my 533mghz system is just too long in the tooth, though
low latency patches help, and the preemtive patch helps, I still get xruns
when recording, even when I just use arecord from the command line. I need
to get a new motherboard, hard drive, and power supply, even an upgrade to
just a 933mghz processor would be a big improvement, also upgrading to the
max amount of ram, for audio apps it really helps to run the fastest
system you can afford, but if I'm wrong here, someone please correct me
before I spend tons of $$ upgrading my system :-), also make sure you're
not running lots of services at the same time, like don't run sendmail
while you're trying to record.
Basically this clicks are cause by overruns, when I run arecord it prints
out a message to the command line evertime an over run occurs, and these
messages correspond to the clicks I find in the finished recording. My
laptop is 833mghz and does better at recording than my desktop, but its
limited by the fact that its got a cheap laptp soundcard. I'm wondering if
I would do better with a usb audio device for my laptop and just use the
desktop as a server and do all my recording on my laptop? It seems that
usb audio still has some problems, I'm wondering to what extent people are
getting high end results from their usb audio recordings, or if the same
xrun problems occur with those as well?
