Virtual Surround-Sound Technology Ported To Audio Devices

SRS Labs Inc. has transferred its TruSurround HD virtual surround-sound audio technology to Tensilica’s HiFi 2 Audio Engine for Xtensa processors and the Diamond Standard 330HiFi Audio Processor. SRS TruSurround HD is well-suited for designers of system-on-chip devices for the mid-range and high-end digital television and digital home entertainment markets. The technology uses proprietary algorithms to enhance signal clarity and improve the intelligibility of dialog, while psychoacoustic techniques maximize the perceived bass response. SRS TruSurround accepts any input source, up to a seven-channel (6.1) audio source, and renders surround sound for 2.0-3.1 speaker configurations.

Tensilica’s HiFi 2 Audio Engine is optimized with hundreds of specialized audio instructions to increase code density (reducing memory requirements) and lower power (reducing frequency requirements). This makes it very efficient for a wide range of audio-enabled consumer products. By adding SRS TruSurround HD to its library of available audio decoders and encoders, Tensilica expects to expand the popularity of its HiFi 2 Audio Engine to designers of popular digital television sets. TruSurround HD is available directly from SRS Labs for licensees of Tensilica’s HiFi Audio Engine or Diamond 330HiFi Audio Processor. To learn more, go to www.srslabs.com or www.tensilica.com.
