Circle Surround® Technology

SRS Circle Surround® (CS) is an advanced, highly versatile, patented multichannel encode system capable of supporting a wide range of surround sound creation and playback applications.

Circle Surround encoding provides the capability to encode up to 6.1 channels of audio for transmission or storage over two output channels or standard two channel carriers. This represents a substantial improvement over previous Lt/Rt based encoding systems, which are not as well suited to handle modern, multichannel media with more than four channels of audio. This means live television and radio can be delivered for playback and broadcast in surround sound through existing stereo infrastructures. Circle Surround encoding is also backward compatible with mono, stereo and all matrix decoders.
