AUSTIN, Tex. --Cirrus Logic Inc. here has announced a licensing agreement with SRS Labs Inc. for the Santa Ana, Calif., company's TruSurround technology, which Cirrus will offer as a customer-selected option on its family of audio decoders.
Using Cirrus Logic's firmware support, integrators can download production-ready TruSurround algorithms from Cirrus Logic. This process enables TruSurround implementation simply by loading the appropriate algorithms in the firmware. No complex circuitry or design changes are required, Cirrus said.
"Cirrus Logic is perfectly positioned with its Crystal entertainment class digital signal processors," said Terry Richie, vice president of DSP strategic marketing for Cirrus. "Because in the same entertainment DSP chip, we're able to provide bonus features like SRS Labs' TruSurround at no extra hardware costs, in the end making it easier and less expensive for our customers to clearly distinguish their products with key new algorithms.
TruSurround is a Dolby-certified virtual audio technology that creates an immersivesurround sound experience from just two standard speakers. It was originally designed to take advantage of the 5.1 channel audio for DVD, without requiring the use of six speakers. TruSurround processes the six discrete channels of digital audio into just two channels, retaining all of the original audio information and giving the listener the perception that additional "phantom" speakers surround them.
"We've enjoyed a strong relationship with Cirrus and are pleased with their success in the wide scale distribution of our surround sound technologies," said Tom Yuen, chairman of SRS Labs. "Now the world's best virtual surround technology, TruSurround, has become easily available through the innovative design of Cirrus Logic's latest chip set."
