Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Shader based audio processing stream

Readme

Webgl-based audio processing stream.

npm install audio-shader

var AudioShader = require('audio-shader');
var Speaker = require('audio-speaker');

//Create shader stream based on sound processing function
AudioShader(`
	vec2 mainSound( float time ){
		return vec2( sin(6.2831*880.0*time)*exp(-3.0*time) );
	}
`)

//Send generated sound to speaker
.pipe(Speaker());

API

API is fully compatible with shadertoy to copy-paste and run it’s code locally. Note that shadertoy limits output sound to 60s, whereas audio-shader runs till it is stoped.

It also might be found helpful to use glslify to get code inserted neatly:

//index.js
var Shader = require('audio-shader');
var Speaker = require('speaker');
var glslify = require('glslify');

Shader(glslify('./sound.glsl'), options?).pipe(Speaker());
//sound.glsl
vec2 mainSound( float time ){
	return vec2( sin(6.2831*440.0*time)*exp(-3.0*time) );
}

Audio-shader can also be used as a processing stream. It inherits audio-through, which is basically a transform stream, so it can be used with other node streams.

var MusicXML = require('musicxml-to-pcm');
var Processor = require('audio-shader');
var Speaker = require('speaker');

MusicXML()
.pipe(Processor(`
	vec2 main (float time) {
		//TODO test this example and document it, shadertoy is down
		return vec2();
	}
`))
.pipe(Speaker());
