SRS Labs ported its TruSurround HD virtual sound audio technology to Tensilica’s HiFi 2 Audio Engine for Xtensa processors and the Diamond Standard 330HiFi Audio Processor. SRS TruSurround HD is ideal for the midrange and high-end digital television and digital home entertainment markets. Tensilica’s HiFi 2 Audio Engine is the most popular commercial audio processor core for SOC designs, and this year Tensilica’s customers are forecasting they will ship 100 million HiFi Audio Engine enabled processor cores in a wide variety of consumer devices.

SRS TruSurround HD accepts any input source, up to a seven-channel (6.1) audio source, and renders surround sound from 2.0 – 3.1 speaker configurations. When televisions featuring SRS TruSurround HD receive multichannel or Lt/Rt content, TruSurround HD virtualizes the channels, creating “phantom” speakers that appear to extend all around the listener, providing a superior multichannel surround sound effect. When the audio source is mono or stereo, TruSurround HD creates an expansive three-dimensional sound field, provides definition to high frequencies, and offers a center control feature to adjust the mix of center information.
