Jsxfr is a simple 8-bit blip, laser, coin and explosion synth, heavily based on Dr Petter’s awesome sfxr. It uses beads for sound synthesis.
Jsfxr is available in two one version. The applet version runs from the browser. The expanded version supports saving and loading of files, and is currently available as an Eclipse project (whoops I lost the code :o). If you would like to see an executable version then leave a comment and I’ll upload one.
