Hi Joseph,

``octave:3> record(5);
Please hit ENTER and speak afterwards!

5+0 records in
5+0 records out
40000 bytes (40 kB) copied, 5.12878 s, 7.8 kB/s
cmd = dd if=/dev/dsp of="/tmp/oct-4MT1kT" bs=8000 count=5''

It appears that there were 5 seconds recorded, with 8 kHz sampling. Assuming
that 7.8 kB/s is 7.8 kByte per second, it seems to be 8 Bit depth per
sample. There is a setaudio() function, but I am not quite aware what it
takes.

Best,
Gaston
