jlturner / jfxr

A browser-based tool to create sound effects for games.

Jfxr is a browser-based tool to generate sound effects, for example for use in games. It was inspired by bfxr, but aims to be more powerful and more intuitive to use.

FAQ

Can I use these sounds commercially?

Yes! Any sound you create with jfxr is entirely yours, and you are free to use it in any way you like, including commercial projects.

Is attribution required?

Attribution is not required, but I would really appreciate if you could link back to jfxr in some way. I would also be delighted if you send me a link to your creation!

Can I send you money?

Thanks for asking! If you want to express your appreciation for this project, you can send donations via this PayPal link.

How does it compare to sfxr/bfxr?

Compared to bfxr, the only missing feature is the mixer (which mixes multiple generated sounds together). There is an open issue to address that. Some filters also have a slightly different meaning, most notably the bit crunch, which is a real bit crunch rather than a downsample.

What are the system requirements?

Jfxr has been tested on the latest Chrome and Firefox, on Linux and OS X. In other modern browsers, I guarantee that the sliders will look broken, but hopefully everything else will still work.

Technical details

Jfxr uses Angular.js for its UI and module dependency management. It relies on several modern web technologies: WebAudio, canvas2d, local storage and of course CSS3.

Developing

Clone the repository and open index.html locally in your browser. This should just work.

To produce production assets (minified JavaScript, CSS and images), you need node.js installed. To run the Grunt tasks, you also need the grunt command-line tool; if you don't have it:

sudo npm install -g grunt-cli

To install the dependencies of the packaging system, just run:

npm install

Finally, to build production assets:

grunt

This produces output in the dist directory, which can be used locally or copied to a webserver.

License

The code itself is under a three-clause BSD license; see LICENSE for details.

Any sound effects you make are entirely yours to do with as you please, without any restrictions whatsoever.
