Подробнее о продукте
DTS Neural UpMix technology can output 5.1 or 7.1 multi-channel surround sound from stereo (227 mode) or 5.1 (527 mode) source material. The technology spectrally separates individual audio elements and places each in its intended location within the surround environment. This results in unparalleled image placement and audio depth. It is widely used in XM satellite radio. Up mixing on stereo decoded sources such as 2.0 Dolby digital, AAC, MP3, WMA etc, is also possible.
Each module supports the Analog Devices, Inc. (ADI) Blackfin or SHARC Processor family and is a licensed product that is available in object code format. Recipients must sign or accept a license agreement with ADI prior to being shipped or downloading the modules identified in the license agreement.
