Audio and voice engines for ARM-based systems

Spirit DSP's Spirit Audio and Voice Engines are now optimised for the ARM AudioDE platform and support all ARM RISC processors available today.

Spirit DSP's Spirit Audio and Voice Engines are now optimised for the ARM AudioDE platform and support all ARM RISC processors available today.

Spirit has been ARM's preferred strategic global software partner since 2006 and ARM now promotes SPIRIT audio and voice products worldwide.

The Spirit Audio Engine is a plug-and-play multimedia system that brings audio playback and record capability to mobile platforms.

The engine is optimised to achieve maximum power efficiency along with standards compliance and highest sound quality.

The TeamSpirit Voice and Video Engine integrates network and voice subsystems providing all required functions 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", says 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 optimised voice and audio software for RISC cores also allows freeing up the DSP, thus leaving more MIPS for extra video processing".

Running the speech-processing components of the Spirit Voice Engine on the AudioDE platform will offer the potential not only to dramatically prolong playback time, but also to 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.
