Encoding 5.1 Surround Sound to Stereo
DTS Neural Surround DownMix technology reduces 5.1 surround sound to a stereo mix that accurately represents the 5.1 original. The stereo signal is also backward compatible with other matrix style decoders.
The DTS Neural Surround DownMix uses an analysis and correction process before the six individual surround streams are combined. By analyzing intensity, time, coherence, polarity and phase characteristics, the signals are transformed into pure intensity and coherence before they are encoded into the stereo mix.
This process eliminates problems that traditionally occur in matrix surround encoded systems, such as comb filtering, spatial distortion and signal loss. DTS Neural Surround DownMix creates a natural sounding stereo mix that is spatially true to the original 5.1 mix.
DTS Neural Surround DownMix Key Features Include:
- Near-perfect mapping of 5.1 surround elements into the stereo field.
- Active correction to fix issues such as comb filtering, spatial location and distortion
- The convenience of a matrix surround encode/decode system with the performance of modern day perceptual audio codec’s
- Backward compatibility with matrix decoders
Applications
Quality Control for broadcasts to Neural Surround Consumer Devices, DTV Broadcast Facilities, Mobile Production Trucks, Production Studios, and HD Radio Broadcasts.
