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

MP3.js - a JavaScript MP3 for Aurora.js

MP3.js is a refactored version of JSMad designed to run in the Aurora.js audio framework. It supports all of the features of JSMad and is released under the same GPLv2 license. The code was reorganized a bit, and now uses all typed arrays for decoding at better performance.

MP3.js adds support for layer I and II to the existing support for layer III. It also supports free bitrate streams, and improves performance thanks to the use of typed arrays.

Demo

You can check out a demo alongside our other decoders alac.js, flac.js, and AAC.js. Currently MP3.js works properly in the latest versions of Firefox, Chrome, and Safari.

Authors

JSMad was originally written by @nddrylliog, @jensnockert, and @mgeorgi during a Music Hack Day. The refactor for MP3.js was performed by @devongovett.

Building

We use browserify to build MP3.js. You can download a prebuilt version from the Github releases page. To build MP3.js for the browser yourself, use the following commands:

npm install
make browser

This will place a built mp3.js file, as well as a source map in the build/ directory.

MP3.js depends on Aurora.js, our audio codec framework. For detailed information on how to use Aurora.js, check out the documentation.

License

MP3.js follows the same jsmad license. MP3.js is available under the terms of the GNU General Public License, Version 2. Please note that under the GPL, there is absolutely no warranty of any kind, to the extent permitted by the law.

Future

  • MPEG 2.5 is not supported.
  • Most of ID3v2.2 and ID3v2.3 are implemented, but some tags are missing.
