I agree. There’s a bit of mental overhead related to working with audio worklets (you have to load them from an URL or a blob URL, etc.) but for square waves in particular the logic should be fairly straighforward, the process function just needs to output 1 or -1 for any given sample.

It needs to do a lot more than that if you want to have something that doesn't alias like crazy. And significantly more if you want it to sound like a game boy.

Well, the output of the wave shaper approach in the article is exactly the same sharp digital square wave that you'd get from a trivial square wave generator.

But I overlooked the point that the GP mentions that the processor source code must be loaded from a separate JS file. That's some quite annoying overhead.
