I kinda doubt this thread is anti-necropost, so I figure I'll share a little utility a buddy of mine pointed out a while back. I'm not exactly sure how well-known it is.

(Now that I posted the link, I noticed he's also the guy who made Sculptris, which I just discovered from a few threads upward. He's got a few nice little proggies actually...)
His original announcement of the project sums it up best:
[quote:2qo0kdev]What I present here is, if you will, an MS Paint for sound effects? or something along those lines. It?s meant to make it dead easy for anyone to whip up a few simple sound effects and save them as .WAV files for playback using most game/media libraries like SDL or pygame.
Basic usage involves clicking the left-most buttons to automatically generate random sounds loosely targeted at certain categories. For more advanced users it?s possible to spend some additional time to manually create fairly varied and interesting sound effects.
The interface is based entirely around sliders for controlling sound parameters, along with a few buttons. Even if you don?t want to spend time learning about all the sliders you can still have some fun just hammering away at them and listening to the various sounds that come out.
Oh yeah, and it's free. Go grab it and enjoy the Random button for your 8bit creations.
Edit: Sorry, this post was so needless. Just noticed a thread on this from a while back. Oops!)
