Sonoris Dither is a professional, high quality audio plugin for mastering purposes. With this plugin you can quantize audio to a lower bitdepth with dither and/or noiseshaping. The dithertype is selectable between TPDF and High Pass (HP) TPDF. TPDF is short for Triangular Probability Densitity Function, a form of dither that eliminates non-linear distortion during re-quantization and has no signal modulation artifacts.

The noiseshaping can be set to three flavours: Curve A, B and C or "Off". It is also possible to set noiseshaping without dither.

The output bitdepth can be set to 16 and 20 bit or "Off" for no quantization.

Features:

• Supports 2 dither types:
  - TPDF (Triangular Probability Densitity Function)
  - HighPass TPDF

• 3 noiseshaping curves:
  - Curve A: 5th order
  - Curve B,C: 9th order

• Dither and noiseshaping independent adjustable
• Dither is generated in assembly language
• Quantization to 20 or 16 bit
• Full automation possible
• Low CPU load
• Settings can be saved
• 64 bit integer math throughout the signal path, except for the noiseshaping filters

New in v1.1

• Small bugfixes.
• Mouse-wheel control.
