Look for the "KSW Sound Restorer 2020" or "KSW Sound Restorer Legacy" bundle on二手 forums (KVR, Gearspace). Older versions often use a serial-only system that still works.

The 2021 edition moved away from traditional, purely subtractive noise reduction methods. Instead, KSW implemented a hybrid engine that combines spectral repair with machine learning inference.
The standout feature is the system. You loop a selection of only noise (e.g., the lead-in groove of a record), hit "Learn," and the plugin analyzes the noise fingerprint. It then subtracts that specific profile from the entire track. This is old-school spectral subtraction, but KSW executed it with exceptional transparency.
