5.1 to Stereo DTS Neural Surround DownMix

Model: DTS Neural Surround DownMix

  • DTS Neural Surround™ DownMix enables the transport of 5.1 surround sound through any stereo infrastructure
  • Process is based on the principle that both natural stereo and 5.1 content are two-dimensional, both contain width and depth spatial attributes
  • DownMix can represent six channels of discrete audio sources in a stereo downmix by transforming the source positions into pure intensity and coherence
  • Available for the Selenio™ MCP, Selenio 6800+™, X100™ and X50™ processing platforms

The DTS Neural Surround™ DownMix provides a process for taking a 5.1 mix and creating a stereo mix. This is called a LtRt watermarked signal and is backwards-compatible with Dolby® ProLogic® II. The stereo mix can be monitored, mixed, stored, edited and played back using a stereo audio infrastructure.

By transforming signal sources, intensity, time, coherence, polarity and phase into pure intensity and coherence before the six channels are combined, the DownMix amelio-rates problems suffered in traditional matrix encode systems (comb filtering, spatial distortion, etc). This proprietary DTS Neural Surround™ process, or watermark, guarantees that surround information is faithfully reproduced when later rendered by the UpMix and is backwards-compatible with Dolby® ProLogic II®. The stereo mix can be monitored, mixed, stored, edited and played back using a stereo audio infrastructure. In brief, the DownMix produces a stereo DownMix that accurately represents the original content, whether monitored in mono, stereo, matrix or Neural 5.1 Surround Sound.

The Selenio 6800+ platform includes the all-in-one APM6803+ and DAPM6802+ Advanced Audio Processing modules.

There is a plug-in option available for adding the DownMix to the Selenio X50™ and Selenio X100™ video and audio processors.

The Selenio™ Media Convergence Platform supports DTS Neural Surround™ DownMix as well.

Versions are available (see ordering information) for applications where DownMix and Loudness Control are required.

  • When a 5.1 mix requires loudness control with a 2.0 downmix for simultaneous 5.1 and 2.0 output.
  • When a downmix is required with loudness control – 5.1 mixes have a very wide dynamic range that requires loudness control for the stereo 2.0 downmix.

    Commonly used in: production studios, audio monitoring, DTV facilities.
