As3Sfxr is a port of sfxr from C++, using the new sound and file capabilities of Flash Player 10. Some of its features:

  • Asynchronous caching
  • Cache-during-first-play
  • Automatic cache clearing on parameter change
  • Faster synthesis

Choose from 4 different oscillators – square, saw, sine and noise. Adjust the 22 parameters to find a sound effect you like. Then save it out as a .wav file, or save the parameter settings to load back in later and tweak the sound further.

Features 7 ‘generator’ functions, which produce random but familiar game sounds such as pickup/coin, laser/shoot and explosion.
