I can shed some light.

rec is an unix command altho' not well supported, slackware 8 has it included.
rec --help shows a lot but thses are relavant to the question;
-c, --channels=CHANNELS specifies the number of sound channels in FILE
-d, --device=DEVICE use DEVICE for input/output
-f, --format=FORMAT specifies bit format of sample
FORMAT is either s, u, U, A, a, or g
-r, --rate=RATE sample rate in hertz of FILE
-s, --size=SIZE interpret size of sample
I think this one could be an help -s xxxxxxxb
SIZE is either b, w, l, f, d, or D
-t, --type=TYPE specifies file format of FILE
Now you could use trail and error and see how big one song is and then define
the byte size.
rec should then exit without crtl-c.

Agreed.
