The SSM2000 is a stereo noise reduction system with adaptive threshold that can achieve up to 25dB of noise reduction from virtually any audio source without sonic artifacts.
The document provides a comprehensive overview of the SSM2000, an advanced audio noise reduction system based on proprietary HUSH circuitry. Key features include up to 25 dB of noise reduction from virtually any audio source without sonic artifacts, single-ended operation that eliminates the need for encode-decode processes, and an adaptive threshold that dynamically adjusts to changing nominal signal levels.

No, there are no royalty requirements for using this system.
Yes, it effectively decodes Dolby B encoded sources with excellent results.
The typical THD+N at 1 kHz with noise reduction off is 0.02%.
