I saw Neural UpMix in action at DTS's surround listening/audition room and was impressed by the plug-in's sonic accuracy and faithfulness to the original source audio. DTS claims, that when Neural UpMix-processed audio is down-mixed to stereo, such as in home stereo systems, there are no disturbing digital artifacts or anomalies generated.

The simple interface in the Neural UpMix GUI includes a Width control (when up mixing from encoded stereo (or LtRt) that controls the ratio of the discrete center channel (where most dialogue is heard) to the phantom center channel as produced by the left and right front speakers. The Depth control sets the overall surround spread for 5.1 up mixes or sets the rear surround spread for 7.1 up mixes. The plug-in also includes a peak limiter to control any distortion causing peaks and all its parameters are automatable. Furthermore, Neural UpMix runs in AudioSuite for faster-than-real-time rendering of up mixes.
