In the digital modeling of analog synthesizer filters using standard digital elements, a saturation element is usually included in the structure. This paper discusses some of the options available for soft clipping saturation elements. It then presents three different filter configurations that include saturation. A review of perceptual techniques for assessing distortion is made to select a suitable evaluation criterion: Timbral warmth being found as the most relevant. Experiments are carried out to apply this to the structures proposed. The conclusion suggests which structure might be most interesting musically.
