How to Use

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 create new sounds

Here are a few more examples examples...

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

ZzFX Music

ZzFX now supports music via ZzFXM by Keith Clark!
Both the player and songs are super tiny and compress well
NoteCraft can also export to ZzFXM
