Yes, I'm referring to the (Sony) Noise Reduction 2.0 Plug-in which is available under FX Favorites/Organize/Direct X on the Sound Forge Audio Studio 14 program. Can this be activated?
Audio Studio (AS-14) includes restoration plug-ins, but AFAIK, not the NR-2.0 suite, which back in the SCS days was a separate installation, serial number and activation. Did you have NR-2.0 prior to AS-14? If so, the serial # would be listed in the Service Center> 'My Products'. I suggest contacting Magix Customer Service Sales Team for a definitive answer and help.
FWIW, Sound Forge Pro, includes the legacy NR 2.0 suite and iZotope's RX Elements.
