ZzFX Sound Designer

ZzFX Music

ZzFX Sound Board Demo

ZzFX is a JavaScript sound effect engine and creation tool

  • Sound effects can be generated or manually created using the web based sound designer.
  • Just include ZzFX.js to load ZzFX, it does not need to be initialized.
  • Or you can use ZzFX.micro.js a tiny (<1k) version that has only the ability to play sounds.

To play a sound in code, just call a simple function! Here are some 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

Here is all the code you need to play ZzFX sounds!

zzfxV=.3    // volume
zzfx=       // play sound
(p=1,k=.05,b=220,e=0,r=0,t=.1,q=0,D=1,u=0,y=0,v=0,z=0,l=0,E=0,A=0,F=0,c=0,w=1,m=0,B=0)=>{let M=Math,R=44100,d=2*M.PI,G=u*=500*d/R/R,C=b*=(1-k+2*k*M.random(k=[]))*d/R,g=0,H=0,a=0,n=1,I=0,J=0,f=0,x,h;e=R*e+9;m*=R;r*=R;t*=R;c*=R;y*=500*d/R**3;A*=d/R;v*=d/R;z*=R;l=R*l|0;for(h=e+m+r+t+c|0;a<h;k[a++]=f)++J%(100*F|0)||(f=q?1<q?2<q?3<q?M.sin((g%d)**3):M.max(M.min(M.tan(g),1),-1):1-(2*g/d%2+2)%2:1-4*M.abs(M.round(g/d)-g/d):M.sin(g),f=(l?1-B+B*M.sin(d*a/l):1)*(0<f?1:-1)*M.abs(f)**D*p*zzfxV*(a<e?a/e:a<e+m?1-(a-e)/m*(1-w):a<e+m+r?w:a<h-c?(h-a-c)/t*w:0),f=c?f/2+(c>a?0:(a<h-c?1:(h-a)/c)*k[a-c|0]/2):f),x=(b+=u+=y)*M.cos(A*H++),g+=x-x*E*(1-1E9*(M.sin(a)+1)%2),n&&++n>z&&(b+=v,C+=v,n=0),!l||++I%l||(b=C,u=G,n||=1);p=zzfxX.createBuffer(1,h,R);p.getChannelData(0).set(k);b=zzfxX.createBufferSource();b.buffer=p;b.connect(zzfxX.destination);b.start();return b}
zzfxX=new(window.AudioContext||webkitAudioContext) // audio context
