If you have access to several computer GNU Parallel http://www.gnu.org/software/parallel/ makes it possible to have those computers help do the computation. E.g. convert all .wav to .mp3 using local computer and computer1+2 running one job per CPU-core:

find . -type f -name '*.wav' | parallel -j+0 --trc {.}.mp3 -S :,computer1,computer2 "lame {} -o {.}.mp3"
