With Sonoris Dither you can re-quantize audio to a lower bit-depth with dither and/or noise-shaping. The dither noise-type is selectable between TPDF and High Pass (HP) TPDF - TPDF is short for Triangular Probability Density Function, a form of dither that eliminates non-linear distortion during re-quantization and has no signal modulation artifacts. The noise-shaping can be set to three flavours: Curve A, B and C or "Off". It is also possible to set noise-shaping without dither. The output bit-depth can be set to 16 and 20 bit or "Off" for no quantization.
