This page tests a browser's support for different wav file codecs
and sampling rates.
All the sound files on this page are based on a public domain "evil
laugh" sound bite that I found at
http://simplythebest.net/sounds/WAV/sound_effects_WAV/people_wavs_2.html
It's about 7 seconds long, and the file sizes are given in case you want to
compare.
