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 🙏

Readme

Is it a banger?

answer. yes.

This is a WebAudio API library written with Typescript

infinite polyphony! randomized sounds!

Usage

Banger

  • single soundfile player
  • pitch variation
  • polyphonic!

Example

const banger = new Banger({
  name: 'Kick',
  arrayBuffer: await getWav(
    'https://cwilso.github.io/MIDIDrums/sounds/drum-samples/CR78/kick.wav',
  ),
})

banger.loading // state while sources is loading (can be used for ui loading screens)

banger.play() // plays the sound!

MultiBanger

  • takes a folder of sounds
  • randomizes playing of said sounds
  • does the things the Banger does
  • is dank
  • probably needs some kind of optimization

Example

const files = [
  'https://cwilso.github.io/MIDIDrums/sounds/drum-samples/CR78/kick.wav',
  'https://cwilso.github.io/MIDIDrums/sounds/drum-samples/CR78/snare.wav',
  'https://cwilso.github.io/MIDIDrums/sounds/drum-samples/CR78/hihat.wav',
  'https://cwilso.github.io/MIDIDrums/sounds/drum-samples/CR78/tom1.wav',
  'https://cwilso.github.io/MIDIDrums/sounds/drum-samples/CR78/tom2.wav',
  'https://cwilso.github.io/MIDIDrums/sounds/drum-samples/CR78/tom3.wav',
]

const multiBanger = new MultiBanger({
  name: 'drumz',
  arrayBuffers: await getWavs(files),
})

multiBanger.loading // while sources are loading.

multiBanger.play() // plays a random sound!

Additional Parameters

along with the basic usage you see above, both players takes the following params in the constructor

type PlayerParams = {
  volume?: number // set the volume of the player 0..1
  reverse?: boolean // play audio in reverse
  loop?: boolean // play audio in a loop!
  drift?: number // detunes the audio this random amount each play
}

Spatial Audio (wip)

currently only 2d panning, attenuation, and head simulation, but it's still fun to use.

const ttib = new SpatialLooper({
  name: 'Looper: Tezos Till I Bezos',
  loop: true,
  arrayBuffer: await getWav(map['tezos'].src),
  onLoaded: () => console.log('>> ttib loaded'),
  onEnded: () => console.log('>> ttib sound ended'),
  onFail: console.error,
  // @ts-ignore
  worldPosition: state.sourceWorldPosition,
  // @ts-ignore
  audibleDistance: 100, // distance in units until audio is not heard
})

// if audio emitter position has changed
ttib.setWorldPosition(
  sourcePosition, // [x, y, z] (y is up)
)

// upon changing of listener position
const [angle, distance] = ttib.get3dValues(
  listenerWorldPosition,
  listenerWorldOrientation
)

ttib.setSpatialValues(angle, distance)
