SRS purchased it from Rocktron and after years of R & D, they refined Circle Surround into a flexible world-class encode/decode solution that rivals discrete digital formats. Besides, with a discrete digital format to promote, it appears that little attention has been given to improving upon it (other than the basic 5.1 PLII offering).Ĭircle Surround was developed by a company called Rocktron as a surround format specifically designed for music. For over 20 years this model has aged and is now long-in-the-tooth given the multidude of new surround formats today. Pro Logic and PLII are methods for decoding Dolby Surround (four channel L, C, R, S) encoded material into 4.0 (PL) or 5.1 (PLII). Circle Surround is not based on SRS 3D to create virtual surround. SRS 'Wow' technology features SRS 3D as part of it. SRS was a 3D stereo imaging enhancement that blew away basic stereo. SRS began with a strong presence in the sound card market with the original, Hughes Aircraft developed technology known as 'SRS'. CS or CSII decoding are also available from Kenwood, Marantz, Theta, Accuphase, Jaton, Gemini and more are in the works! (I'd tell you but I'd have to kill you) They presently do not offer CSII, but are evaluating it. Theta Digital manufactures high end AV Receivers that feature Circle Surround decoding (5.1). 'Is circle surround II on this card the same as the one found in the $10,000 Theta CB2 pre-amp? ' To address one specific question from the M-Audio thread: M-Audio's decision to use Circle Surround II decoding in these new products suits the name of the product well, for it is a revolutionary step in consumer sound cards. I am now the Product Marketing Manager for Circle Surround technology at SRS Labs.

I was a key player in the evangelism of EAX to game developers and the successful launch of both the SB Live! and Nomad MP3 product lines. I also spent close to 5 years at Creative Labs. Another product I worked with was the PCMCIA Sound Canvas SCP-55. I spent three years t Roland, inheriting the RAP-10 sound card and launching the SCD-10 and SCD-15 wavetable daughterboards. I will try to address the questions brought up on the other thread.įirst, since I'm new here I'll give you a little background on my history. Since the thread on the M-Audio Revolution and Sonica Theater seemed to have questions about Circle Surround II I thought I might be able to provide some insight to the value this represents for sound card enthusiasts and consumers alike.
