SPIRIT Voice & Audio processing doubles playback and talk time on mobile handsets

3GSM World Congress – Barcelona (Spain) – February, 12, 2007 – SPIRIT DSP, the world’s leading provider of embedded voice, audio and video software products, announced today that SPIRIT Audio and Voice Engines are now hand-optimized for the ARM AudioDE™ platform and support all ARM RISC processors available today.

In 2006 ARM selected SPIRIT as preferred strategic global software partner. ARM now promotes SPIRIT audio and voice solutions worldwide. Today’s announcement is another step forward in the ARM-SPIRIT partnerships.

The SPIRIT Audio Engine is a plug-and-play multimedia solution that brings audio playback and record capability to mobile platforms. The engine is optimized to achieve maximum power efficiency along with standards compliance and highest sound quality.

The TeamSpirit® Voice & Video Engine integrates network and voice subsystems providing all required functionalities to guarantee high quality VoIP over WiFi and 3G connections on mobile and embedded platforms.

“Both compact Audio and Voice engines are in high demand now due to release plans for multimedia and dual-mode phones and PMPs by almost every major OEM,” said Slava Borilin, VP Products at SPIRIT. “SPIRIT embedded software products use all the computational potential of audio subsystem and multimedia systems-on-chips. SPIRIT technology can move voice processing to the audio subsystem to unload the application core. Highly optimized voice and audio software for RISC cores also allows freeing up the DSP, thus leaving more MIPS for extra video fps”.

Running the speech processing components of the SPIRIT Voice Engine on the AudioDE™ platform will not only dramatically prolong playback time, but also reduce power consumption during VoIP calls by 55%.

The SPIRIT Audio Engine is now available for all ARM RISC cores from ARMv4 to ARMv7 with NEON™ technology and AudioDE™, as well as for a number of DSP processors including TI C5000, C6000 series and ADI BlackFin®.
