Kees Jan Koster:

|If you are, what software are you using?
Well, when I record off TV (line-in), I use fxtv. It manages the sox and
mpeg encode invocations to convert to whatever format I want at the time.
For other stuff, I use a few little cmd-line utils to play and record raw
audio. I uploaded a copy of these to Amancio's box a while back for sound
driver debugging, ...and I see there still there so here's the URL:
ftp://rah.star-gate.com/pub/dsp-recplay.tgz
Just "make".
Then to record, use xmix or your favorite player to select the recording
source and jack the gain up on it, then:
dsp-record -r rate -b bits -c channels -d duration(sec)
e.g.:
dsp-record -r 44100 -b 16 -c 2 > RAWAUDIO
To play back, feed to dsp-play with the same args:
dsp-play -r 44100 -b 16 -c 2 < RAWAUDIO
BTW, valid <bits> are: mulaw, ulaw, alaw, adpcm, 8, u8, 16, s16le,
s16be, s8, u16le, u16be, mpeg. Support depends on your card and sound
driver's capabilities.
