jsfx - Javascript Sound Effect Generator
Jsfx is a javascript library (with frontend) for sound effect generation. The generation is based on sfxr. Jsfx needs WAV support from browser to work. For short clips it can generate the audio in 30ms in a good browser. Might be fast enough to do runtime generation of effects.
You can modify the sound effect by add new paramater array to the libarary section. This array can be used to generate the audio at runtime, this means no audio downloads.
Requirements: WAV Support Browser
