True random passwords using your microphone noise as seed

TMPFILE="/tmp/$RANDOM$RANDOM$RANDOM$RANDOM$RANDOM" && arecord -d 1 -t raw -f cd -q | base64 > $TMPFILE && pwgen -ys 12 12 -H $TMPFILE $@ && rm $TMPFILE
Generate a truly random password using noise from your microphone to seed the RNG. This will spit out 12 password with 12 characters each, but you can save this into a bash script and replace 'pwgen -ys 12 12' with 'pwgen $@' so you can pass any paramters to pwgen as you would normally do.

What do you think?

Any thoughts on this command? Does it work on your machine? Can you do the same thing with only 14 characters?
