Free Sounds

Adding quality sound to your videos or podcasts can be pricey in the professional world. Take a look at this site: http://www.sounddogs.com/sound-effects.asp.   Unless you happen to be a sound engineer or know a musician with a handful of quality music tracks to lend you, you'll need to find yourself some royalty free sounds.  Here are some of my favorite sites for free sounds.  Please note that while you can download music tracks for free, you may still be required to credit the original artist if you plan to publish any works using the tracks.  Please read all disclaimers when downloading other people's work.
