Software sorts out mobile acoustics

LifeVibes Noise Void, Hands Free and Voice Clarity acoustical software solutions eliminate background noise and echo while improving speech quality in mobile phones and portable multimedia devices

The LifeVibes software products complement Philips' Nexperia semiconductor offerings and the company reckons they will revolutionise the ease with which people communicate and enjoy entertainment over mobile devices. With the widespread adoption of cellular handset use worldwide, consumers increasingly rely on mobile devices to communicate wherever they go.

Answering a phone call in noisy places, such as airports, shopping centres or busy streets, is a common problem with mobile phones.

Consumers often have to shout in order to be heard.

Philips' LifeVibes solves these problems, providing patented technology that will ensure clear, noise-free conversations in even the most adverse environments.

"Philips' LifeVibes sound enrichment algorithms are the result of decades of pioneering work in audio and acoustic research", said Dieter Therssen, Segment Manager Sound Enhancement, Philips Semiconductors.

"The addition of this new family builds on Philips' expertise and innovation in the development of audio solutions for mobile consumers".

Philips' LifeVibes Noise Void background eliminator removes all background noise using the world's first two-microphone spatial filter in mobile devices.

It features better stationary and nonstationary noise reduction than a single microphone setup.

LifeVibes Hands Free echo canceller offers the first truly full-duplex echo canceller for mobile phones, which will eliminate stationary noise caused by ordinary devices such as fans, engines and air conditioners.

With LifeVibes Hands Free in their mobile handsets, users can enjoy clear conference and hands-free calls.

LifeVibes Voice Clarity speech enhancer further improves the quality of speech by enhancing all voice types with any loudspeaker or earpiece, making it ideal for mobile phones and portable movie players.

As a growing family of sophisticated signal-processing algorithms, LifeVibes complements and makes full use of digital audio hardware, adding value to existing audio products.

When combined with Philips' Nexperia System Solution, LifeVibes provides customers with a complete acoustical application.

It can also be embedded in chips without utilising any particular operating system in order to ensure portability from one environment to another.

With LifeVibes, Philips' continues to advance its award-winning audio technologies to benefit customers and end users.
