Adsyn32 generates audio waveforms using Additive Harmonic Synthesis (AHS). AHS builds complex sounds by adding together simple components, usually sine-waves of related frequencies, known as partials. With careful control of the partials amplitude envelopes, it is possible to create dynamic sounds of great subtlety (as shown in much of the work of Wendy Carlos ). It is not an easy technique, and takes time to produce results, particularly in comparison with modern sampled wavetable methods. Adsyn32 is an attempt to make the process easier. This version of the program is released as freeware.
