about jsfxr

Jsfxr is an online 8 bit sound maker and sfx generator. All you need to make retro sound effects with jsfxr is a web browser. It's a JavaScript port of the original sfxr by DrPetter. You can also use it as a JavaScript library for playing and rendering sfxr sound effects in your games.

See the documentation for using these sounds in your JavaScript game.

Tip: use the sfxr-to-wav nodejs script to convert to a wave file on the command line.
