音频和视频

Our world-leading AI capability is revolutionizing end-user experiences, business workflows and manufacturing processes. This drives transformational efficiency and productivity gains for our clients.

Our techniques can identify audio and video characteristics with unprecedented speed and accuracy – from real-time classification of musical genres and spoken word themes, to applying super resolution to damaged or low-grade images.   

We’re pushing audio and video product design beyond convention, using a ‘standards plus’ approach to create unique and industry-leading technologies, while taking advantage of high-volume silicon.

Building on our extensive experience, we apply novel techniques in wireless AV, sound beamforming, voice activation, wake-on-word and echo cancellation.  

Digital audio communications play an essential role in the products we develop, such as codecs carrying voice via satellite or high-quality music over Bluetooth links.

We apply signal conditioning to improve signal quality and enhance audio, whilst driving significant power reductions, adding another dimension to algorithm and processing hardware design.  

Disruptive audio and Internet of Things (IoT) technologies demand an innovative approach to silicon design. Our Sapphyre digital signal processing core increases performance for audio applications against cost, whilst significantly reducing power consumption and device size.

Our Ecoutez platform is the world's lowest power, flexible IP block for accelerating Voice Activity Detection, requiring just 11µW – about 100th of the power consumed by a modern hearing aid.   

Our multi-disciplinary teams have a proven track record of reinventing the possibilities of high-quality audio and video design, time after time.

This includes the world’s lowest-cost internet radio, the world’s first two-way tour-guide radios, pioneering instantly-installed wireless audio descriptions for visually-impaired and hearing-impaired cinema-goers, and a low-cost multi-channel video conferencing system supporting 24 microphones.  

Reliability is critical for live events, programme making and control systems with spectrum an increasingly scarce and valuable resource. Our experience in wireless technology and standards allows us to meet these challenges head-on.

From developing the world’s first fully digital radio transceiver, to advising regulators on spectrum usage, we offer clients a diverse range of expertise that ensures critical projects are delivered with exceptional results.  

We’re proud to have played a key role in the standardisation of Bluetooth, culminating in our spin-out of Cambridge Silicon Radio (CSR), which became the world’s leading supplier of Bluetooth single-chip transceivers.

From bespoke software stacks and processor cores, to innovative radio and antenna design, our expertise offers unprecedented customisation and control to our clients.
