Sonic Network’s Next Generation Audio Synthesis now available in Tensilica’s HiFi Audio Engines

Personal Media Devices Benefit from Market Leading Interactive Audio Generation Capability for Ringtones and Mobile Gaming

BOSTON, MA, and SANTA CLARA CA, February 20, 2006 –Sonic Network Inc., a worldwide provider of audio synthesis technology to the handheld consumer device and musical instrument markets, and Tensilica Inc., the leader in automated configurable processor technology, today announced that Sonic’s Embedded Audio Synthesis (EAS™) technology has been ported to Tensilica’s new Diamond 330HiFi audio processor and the Xtensa® HiFi 2 audio engine. Sonic’s EAS technology has been designed specifically for mobile devices that need both a low memory/processor footprint solution as well as very high quality polyphonic audio.

Jennifer Hruska, president and founder of Sonic Network states “Tensilica’s 24-bit embedded audio processors have significant advantages over the 16-bit audio processors commonly available in the SoC markets, most specifically providing a superior sound quality of the synthesized audio. In addition, with Tensilica’s efficient compiler, we were able to achieve performance levels in C code that are comparable to hand-optimized assembly code on other processors. The specialized instruction set within both HiFi engines allowed us to achieve a low processor footprint very quickly, an important porting goal since our customers are continually striving for higher polyphony on their products.”

Steve Roddy, Vice President of Marketing, Tensilica states, “The availability of Sonic’s EAS on both the Diamond 330HiFi processor core and the Xtensa HiFi 2 Audio Engine provides a pre-integrated and validated, high quality, low risk audio solution that enables SOC designers to quickly design audio-enabled devices such as cellular phones, portable music players, and mobile game devices. We are pleased to add Sonic’s EAS to the growing suite of application software available on our HiFi engines.”

Sonic’s EAS technology on Tensilica’s processors supports the following open standards:

General MIDI Level 1 (GM1)
MIDI Type 0 and MIDI Type 1
General MIDI Lite (GML)
Mobile DLS (mDLS)
Scalable Polyphony MIDI (SP-MIDI)
Synthetic Mobile Application Format (SMAF) including ADPCM
Downloadable Sounds (DLS) and Mobile Downloadable Sounds (mDLS)
Mobile eXtensible Media Format (mXMF)
