u/andrea270872

wow... I have to look into this 2kplus competition
u/rodrigo.siqueira

The game is great! Sound effects could also be generated in pure JS.
u/KilledByAPixel

Thank you! I released a tiny JS sound effect generator that I use for all my stuff. But couldn't fit it in this. https://github.com/KilledByAPixel/ZzFX
u/rodrigo.siqueira

Great JS sound effect library!! I'm playing a lot with it. If you put a Math.ceil around your main frequency (Math.cos), it will convert to square wave and sound like 8bit videogames. See here how it sounds: https://js.do/rsiqueira/audio-zzfx-square-wa…
u/rodrigo.siqueira

May be a small improvement that would bring good results would be to have "exponetial decay" option. And some sounds should not have decay (I implemented a simple decay_flag, if 0 there is no decay). Or may be it can be more generic, using the ADSR envelope model (Attack, Decay, Sustain, Release variables). I'm also trying to play a sequence of notes but the setTimeout for each sound/note does not bring reliable results.
u/KilledByAPixel

thanks rodrigo, i am planning on working on it more and adding a few more params, I want to keep it simple so still deciding!
