STMicroelectronics and Soundchip SA are working together on an in-ear audio accessory that provides the ability to conveniently switch between different audio sources—voice, music or ambient sound – by simply pressing a button, making a pre-defined gesture or issuing a voice command.

Worn like a pair of In-Ear Monitors (IEMs), the smart audio accessory features new means of controlling and personalizing the sound experience, the companies stated. Designed to be worn at all times, the audio accessory supports all use modes, including music, telephony and direct conversation, without requiring any reconfiguration of the apparatus in the ear. The system can also filter out the unwanted background noise.

The audio accessory helps wearer switch between different audio sources using voice commands or gesture recognition. The system will use ST MEMS sensors, including silicon membrane microphones, for a variety of tasks ST said.

In addition, by connecting the system to a DSP or DSP-capable controller, and a smartphone or tablet computer, the sound experience can be further enhanced by taking advantage of custom-made apps, which individually process and mix sound sources to deliver new features, such as augmented reality.

"The smart audio accessory combines the very best of Soundchip's unique audio-system technology for sound at the ear. We believe that the smart audio accessory represents a game changing solution that offers the users of smartphones, tablet computers and gaming devices a level of sound experience only dreamed of until now," said Mark Donaldson, Soundchip CEO.

Switzerland-based Soundchip is the originator of the HD-PA Reference and licences its solutions to those involved in the design and manufacture of audio codecs, processors, sound transducers, multimedia systems and consumer products.
