It's called soundboard, and there are all kinds of free sounds and sound effects - tens of thousands, they say. You can browse the site to find sounds you like, or that fit a particular blog post. Sound boards are organized by category, or you can search for the sound you need. You can download the sounds you want. Sign up for a free account and upload your own sounds, you get 125MB storage, or just add the sounds you like from other members' sound boards. You can even choose a specific sound and embed that into a blog post or website, like this:

(I'm watching a Star Trek special on the History Channel, so I thought this was appropriate)
I suppose my dad could have done the same thing with his whip-poor-will call, but then I wouldn't have had to visit soundboard! I just signed up for my free account because I think this site is going to come in handy.
