This is a sample object with a sample sound sound: /cow/sounds/squirt.wav which will play in IE and only in Firefox with the QuickTime plugin.
Some sounds I have uploaded for common use are: /cow/sounds/clap.wav
/cow/sounds/clap2.wav
/cow/sounds/click.wav
/cow/sounds/click2.wav
/cow/sounds/perpit.wav
/cow/sounds/squirt.wav
/cow/sounds/tink.wav
Long pits of midi music are:
/cow/sounds/flourish.mid
/cow/sounds/jingle1.mid
/cow/sounds/onestop.mid
/cow/sounds/town.mid
There should be no problems (only slight delays) referencing a sound file on any URL
