AdsynDX

AdsynDX is a sound synthesis application for Windows XP. It creates audio waveforms using the methods of Additive Synthesis, constructing complex sounds by adding together simpler waveforms (usually sine waves) of various frequencies and amplitudes.

AdsynDX allows an unlimited number of partials (subject to memory constraints), and (with a suitable soundcard) can create mono or stereo waves at sample-rates up to 96 KHz.
