db?  what?

find / -name '*.wav' -o -name '*.mp3' -exec wc -c '{}' ';' | awk '{a+=$0} END {print a "\n"}'

that will do the trick.  willing to be a bit out of date?  most linux
boxes have locate:

(locate .wav; locate .mp3)|xargs -n 1 wc -c|awk '{a+=$0} END {print a "\n"}'

find / -user 288 -o -size +10k

man find.
