audionodes provides adsr for filtering effects:

Enabling simple filters would make a big deal for recreating realistic sounds with zzfx.

wafxr has that too: https://andyhall.github.io/wafxr/

Thanks for the great library.
Very smart approach to sfx, can be used to describe many basic sounds.
Just a suggestion - is there a sense to add spectrogram to the preview?
I was going to replicate some drum sounds in zzfx, spectrogram is missing...

Hello mate,

What do you think about distributing this awesome tool as a npm package?

Thanks for your help!

Ported ZzFX as a Defold Native Extension.

https://github.com/thejustinwalsh/zzfx-extension

It's a C++ implementation that is using containers provided by Defold, would be fairly trivial to replace the containers and use it as a base for porting to any other C++ program. Check out the Demo of the soundboard also ported to Defold.

I noticed that in the sounds I used for my game there were a number of parameters that are generally undefined, like randomness, pitchJumpTime, repeatTime... however the last two, tremolo and decay are always used, so it's not possible shorten the arrays to take advantage of the defaults.

Perhaps it would be useful to tweak the parameter order for some byte size gains?

Noticed that both ZzFX and ZzFXMicro implement a sign function. In the context where this is used, it can be replaced with Math.sign, which has fairly good browser support.

Happy to provide a PR.

Trying to recreate some real sounds with zzfx I found out it may be helpful to run multiple zzfx simultaneously.
I started thinking would that be something possible/desirable?
I can envision simple API expansion as ZZFX.PlaySamples(ZZFX.BuildSamples(...a), ZZFX.BuildSamples(...b))

(btw: what's the reasoning for naming methods with cap letter? Usually that convention in JS is for classes)

Right now half-cosine is used for modulation, eg.

zzfx.play(...[,0,1925,,2.4,0,,,,,,,,,2,,,.5])

produces the following spectrogram:

Would be nice to have another modulation types, eg. sin:
