ZzFX is a tiny sound generator designed to produce a wide variety of sound effects with minimal code overhead. It's perfect for games, prototypes, and any web application that needs sound without the bulk of traditional sound files.

• Compact: The micro version is under 1 kilobyte uncompressed.
• Versatile: 20 controllable parameters for diverse sound effects.
• No Dependencies: Standalone with no external libraries.
• Cross-Browser: Compatible with nearly all web browsers.
• Open Source: MIT licensed, use it anywhere!

• Code-Driven Sound: Add or change sound effects with just one line of code.
• Lightweight: No sound asset files mean faster download times.
• Prototyping: Ideal for placeholder sound effects.
• Game Jams: Minimal overhead for size-limited competitions like JS13K.
• Not Just for Games: Enhance any website with sound.

• Download from github or use npm install zzfx
• Import ZZFX as a module with using import {ZZFX, zzfx} from './ZzFX.js'
• Or paste the code from ZzFXMicro.min.js
• To play a sound just call zzfx(), something like zzfx(...[,,,,.1,,,,9])
• Use the ZzFX sound designer web app to craft new sounds.

Sample sounds...

zzfx(...[,,925,.04,.3,.6,1,.3,,6.27,-184,.09,.17]); // Game Over
zzfx(...[,,537,.02,.02,.22,1,1.59,-6.98,4.97]); // Heart
zzfx(...[1.5,.8,270,,.1,,1,1.5,,,,,,,,.1,.01]); // Piano
zzfx(...[,,129,.01,,.15,,,,,,,,5]); // Drum
