What's all this then? This is as3sfxr, flash port of sfxr. It makes sounds for your games. You only have to press buttons and listen and press buttons again.
This is great: no need to understand how sound synthesis works, ability learn a little about sound synthesis by pressing buttons/moving controls randomly, no need to download/compile/install anything either. Oh how I would wish for more tools of this kind, maybe specialized stuff like (non-8-bit) fire effect generators, ice effects, explosions... There are some sfx gens for pure data but it will take a little more time to get them running.
At the top of this post, there is an embedded flash applet. If you are a user of an open source flash player: do you see it? Can you use it? How many of you already knew of sfxr but only now did try it through as3sfxr?
I hope this 'no info about games' post does not shock you.
