- Tiny sound generator with 20 controllable parameters
- Play audio via code, no need for sound asset files
- Compatible with nearly all web browsers
- Small code footprint, the micro version is under 1 kilobyte uncompressed
- Can produce a large variety of sound effect types
- Sounds can be played with a short function call. zzfx(...[,,,,.1,,,,9])
- No additional libraries or dependencies are required
- Open source with MIT license, you can use this for anything!
- You can quickly add or change sound effects with just one line of code
- Without sound asset files your game is smaller and faster for users to download
- While prototyping you can use ZzFX for placeholder sound effects
- For size limited game jams like JS13K, ZzFX uses very minimal overhead
- ZzFX is not just for games, you can use it to easily add sounds to any website
- 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 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
