Quack is a non-real-time, modular software synthesizer. It allows you to assemble sound generation and modification modules together to generate a wide variety of electronic sound effects and patches. The output is saved to WAV files.
Quack is modelled on an analog "patch board" synthesizer. It provides a wide variety of audio components - such as oscillators, filters, modulators, envelope generators, noise sources - which can be connected together to produce complex sounds.
Quack can also read in existing WAV files (for example, sounds sampled using Sound Recorder), and incorporate them into sound effects.
