Detailed Description

LA32WaveGenerator is aimed to represent the exact model of LA32 wave generator. The output square wave is created by adding high / low linear segments in-between the rising and falling cosine segments. Basically, it’s very similar to the phase distortion synthesis. Behaviour of a true resonance filter is emulated by adding decaying sine wave. The beginning and the ending of the resonant sine is multiplied by a cosine window. To synthesise sawtooth waves, the resulting square wave is multiplied by synchronous cosine wave.
