[SoX-users] using sox to record on a mac? / timelapse audio

[bet h. h. g. o. a. t. <six...@gm...>]

working on a script to record short snippets of audio every once in a while
and then combine.
can't seem to get the recording working on the mac. maybe i have to
correctly point it to the right audio source. i see something about setting
AUDIODEV in the man pages but not sure how to get to this on a mac. any
tips?

<code>
while [ 1 ]
do
let "counter=counter+1"
echo $counter
sox -d -c 2 snip${counter:1}.wav trim 0 5
sleep 10
done
</code>
