Audio Engine Codec Library Expands With Dolby Pro Logic Additions

Tensilica’s audio codec library for its Xtensa HiFi 2 Audio Engine has been expanded to include Dolby Pro Logic II and Pro Logic IIx decoders. Both Dolby Pro Logic decoders are essential sound processing technologies employed in home-theater AV receivers. Dolby Pro Logic II creates 5.1-channel surround sound from any stereo movie, music, TV, or game audio source, while Dolby Pro Logic IIx extends the sound experience up to a full 7.1-channel configuration.

Tensilica’s HiFi Audio Engine is a fully programmable processor core optimized for audio applications, with a library of over 50 audio software packages. Other Dolby-approved packages include: Dolby Digital Decode, Dolby Digital Creator Encode, Dolby Digital Compatible Output Encode, Dolby Digital Plus 5.1 and 7.1-channel Decode, and Dolby TrueHD Decode.

The Dolby Pro Logic II and IIx decoders are available for shipment now to all Dolby approved licensees of Tensilica’s Diamond Standard 330HiFi or the Xtensa HiFi 2 Audio Engine. Contact Tensilica directly for pricing information.
