Hi all, Since we are posting arecord usage I thought my two cents might help some. arecord -q -d 2820 -f cd -r44100 -c2 -I track1.raw track4.raw I use this to record 47 minutes of, oh lets say a 4 track source, off a standard tape deck. The point is that you can split the channels with the -I switch, if you have a need.

I see that the -d (Duration) was set at 2 hours, that's a lot of disk space. Using alsa 09 beta 10 I use these lines: arecord -d 1800 <filename>.wav This will produce a 8 bit mono file of 14Mb of half an hour. arecord -f cd -d 1800 <filename>.wav Which will record a 16 bit stereo CD quality recording. Can't remember the disk space used for this half an hour recording. A "arecord --help" will tell users what switches are available for their particular version. Providing the little indians don't get you, lol.
