PWMDrive

The PWMDrive VST plugin was developed to be a saturator / softclipper / waveshaper with offset. I came up with the idea when reading about tube-amplifiers where the distorsion wasn't symmetrical around zero.

I called it PWMDrive since, when maxed out, it can produce sounds similar to a pulse-width-modulated square wave.

The waveshaping function is out = in/(1+in)). Actually its like that on positive x, and symmetrical around zero) I'm not sure if this is similar to a "real" tube, but it sounds great, if you have any suggestions on different shape-functions, that have similar (or less) cost, please let me know.

An sweet-sounding oversampling option is provided, mainly meant to be used at mixdown-time, since it's rather expensive.

The steps performed are: - Measure the amplitude - DC-Offset signal depending on amplitude (lfo-controlled) - Gain - SoftClip - HiPass (to remove dc) - Gain
