Neural® Surround UpMix™: Stereo to Surround Sound
Neural UpMix was ranked #1 in double-blind listening tests, outperforming all other methods in channel discreteness, envelopment, and original spatial location.
The Neural Surround UpMix transforms any stereo signal into a surround sound experience. Audio that's downmixed using the Neural® Surround DownMix™ can be restored with the correct information in each of the 5.1 surround channels.
Content that has not been encoded can be translated into width and depth information, creating a pleasing surround image--often indistinguishable from original surround sound content. Matrix-encoded stereo signals (LtRt, ProLogic, Prologic II, SRS Circle Surround) can be upmixed to a surround sound image more discrete than that of the complementary brand matrix decoder.
The Neural Surround UpMix spectrally separates individual audio elements and places each in its intended location within the surround environment. This results in unparalleled image placement and stability. And UpMix does this without taking artistic license with content. Audio is placed exactly where it would be heard in a professional Live End Dead End (LEDE) listening environment.
Key features of the Neural Surround UpMix include:
- Stereo to any channel configuration (2.1, 3.1, 4.1, 5.1, 6.1 or 7.1)
- Great compatibility with all stereo signals (LR, LtRt, LoRo, ProLogic, ProLogic II or SRS Circle Surround)
- Adaptive filters that eliminate "dialog leakage" traditionally found in matrix audio decoders
- End-to-end surround delivery system when combined with the Neural Surround DownMix
DownMix and UpMix
The UpMix can be used as a stand-alone unit to monitor stereo production or in tandem with the Neural Surround DownMix as a complete 5.1 transport solution. The original 5.1 surround content encoded by the DownMix is flawlessly reproduced. Neural Surround DownMix/UpMix makes the transition to surround simple and affordable within existing stereo production or broadcast environments.
UpMix + NLC
Neural Surround UpMix can also be used in tandem with Neural Loudness Control as a complete 5.1 rendering and loudness control solution. This cost-effective solution allows legacy broadcast facilities to start presenting 5.1 audio to their viewers. UpMix + NLC would be positioned directly ahead of the AC3 encoder in this application, providing loudness-controlled 5.1 audio. Refer to the UpMix+NLC page for more information.
Neural Surround MultiMerge™
The Neural Surround MultiMerge uses the exact UpMix algorithm found in the standalone product, but with added functionality and features designed with the broadcast transmission path in mind. Refer to the MultiMerge page for more information.
Applications
