Show HN: Wavepot – Digital audio workstation of the web (wavepot.com)

That said, it's a really clever idea to have all the source editable, since js is an interpreted language anyway. One can imagine a future where the community not only shares songs and sounds, but the DSP units themselves. Unlike desktop DAWs, which rely on dylibs (dlls) to supply external synths and effects, a js-based DAW can load, re-compile and hotswap units on the fly.

I would call it the audio equivalent of OpenSCAD.

I'm glad you like it. The sound is generated purely by a JavaScript function returning sample values that are then handled by the Web Audio API and buffered. That's how you hear sound.

On edit: It's really easy to remix tracks that way, even small changes to values yield quite different results. It's fun!

An oscillator and a filter modulator are pretty much all you need to create this particular app. There's no reverb, and any delay effects are being "hard-coded" with simple degrading velocities. All synthesizers are built from these ultra-simple components, maybe 2 or 3 more and you have everything you need to build a digital synth purely with web technologies.

I'll certainly contribute to this. Will the source be opened up?

Here's a delay filter:

  var delay_array = [];
  var delay_length = 5;
  var delay_feedback = 0.6;
  var delay_volume = 0.4;

  function delay(x) {

    y = 0;
  
    if (delay_array.length < (delay_length * 1000)) {
      delay_array.push(x);  
    } else {
      y = delay_array.shift();
      delay_array.push(x + (y*delay_feedback));  
    }

    return (x) + ( y * delay_volume );
  
  }

  return delay(synth);

Note, this isn't a complaint, it's merely a request to understand why my comment is inappropriate and to understand how I can express my approval of a submission without losing karma.

Also, Find Musicians doesn't seem to be working, at least not in Chrome on osx.

THIS!

Let's build it!
