SampleSwap for free audio samples...
Check out the site sampleswap.org, a sample sharing website that is an Ontology project. Samples can be browsed, auditioned and tossed in a virtual "basket" that is up to 20MB. After the files in the basket are compressed, an email with a link to the file is sent to you and the .zip file is downloaded. There's no limit to the amount of audio you can download either and the cost is absolutely zilch.
There's no guarantee that the uploaded samples are "cleared" samples but the service is a great idea. I've already downloaded a basket of sounds that I found there. I guess I should also upload some of the sounds that I've made that I've contributed to many of my friends but never to a public forum like this.
