Tensilica HiFi Audio DSP Supports Dolby Digital Plus for Surround Sound on Mobile Devices

SANTA CLARA, Calif. - February 27, 2012 - Tensilica, Inc. today announced the immediate availability of Dolby Laboratories' newest technology suite optimized for mobile entertainment experiences - Dolby Digital Plus - on its popular HiFi Audio DSPs.  Now designers of SOCs (systems on chips) for mobile devices can enable stunning audio settings, including full 5.1-channel HD audio.

"We are excited to be working with Dolby on their latest software to enhance the mobile user's audio environment," stated Larry Przywara, Tensilica's senior director of multimedia marketing. "This software package, optimized for our HiFi DSPs, provides an immersive audio experience for mobile handsets and tablets that we expect to enable system differentiation to drive better consumer adoption.  Our first delivery was made to a tier 1 smartphone OEM in Q4 of last year."

"As Dolby technology continues to be adopted by the mobile industry, it is important to have an efficient architecture for low-power mobile devices, which are increasingly used for playing back multimedia content," stated Mary Anderson, Senior Director, Consumer Devices, Dolby Laboratories. "Dolby Digital Plus running on Tensilica's HiFi architecture will provide an uncompromised, HD audio experience for all your mobile devices."

A handset equipped with the newest Dolby Digital Plus technology suite can include a combination of the following features:

  • Dolby Digital Plus Decoder - enabling HD 5.1-channel sound for headphone playback or HDMITM play-out
  • Dolby Mobile Surround Sound- provides 5.1-channel surround sound over any pair of stereo headphones
  • Sound Space Expander - delivers a wide, spacious soundstage for a rich listening experience from speakers
  • Bass Enhancements- provides clean, powerful bass extension
  • High-Frequency Enhancements- adds back high-frequency audio that might be missing from compressed content
  • Mono-to-Stereo Creator - adds depth to the playback of mono content that users download or create
  • Sound-Level Controller - maintains a consistent audio playback level so users can set and forget the volume control
  • Graphic EQ - equalizes audio with two to six user-adjustable bands
