A sound effects generator in the style of SFXR (or its many clones), but with a larger library of sound effects.

Under the hood, it’s a software modular synthesizer with certain limitations—for example, the modules can’t be connected in a cycle. The modules are connected with code in a simple language that checks units, so you write “500ms” instead of “0.5” if you need a 500ms delay. If you write 500Hz instead, that’s an error. This part already works.

On the surface, I’m figuring out how to expose the parameters with simple sliders and knobs in a web page. The idea is that you click a button like “explosion” and then tweak the knobs to get the explosion sound that you want. This is how SFXR (and as3fxr, BFXR, JFXR, etc) work, but they have a fairly limited set of sounds.



Sounds cool. If you haven't already, you might want to check out the Fractal Bits iOS app. It doesn't let you manually adjust parameters, only randomly generate sounds, but it makes some nice ones. It sounds probably FM-based to me.


I’m really going for a purposeful tool here that you can use to get what you want. Something a bit more than SFXR but a lot less than Reaktor.
