CSR Breaks Barrier to Affordable Home Audio Networks

The complementary VibeHub and VibePlayer platforms work together to make it practical and easy to enjoy very high-quality, synchronised multi-room audio anywhere around the home, indoors and out, from local and cloud-based sources over an existing home Wi-Fi network. The VibePlayer platform offers a simple two-chip solution for building low-cost, portable, battery-powered wireless speakers and speaker docks that can be used either stand-alone or as part of a network. The VibeHub platform, based on the CSR Sonata processor, is used to create fully featured intelligent audio hubs for the home that can simultaneously pull content from digital media servers and Internet radio or other cloud services, as well as Bluetooth streaming media source devices, and intelligently route the audio to play on multiple VibeHub- and VibePlayer-based products located anywhere on the home network. The whole system can be controlled using an app on a smartphone, tablet or other smart mobile device.

“Our entry into networked home audio builds upon our experience and expertise as the leader today in wireless audio, enabling us to dramatically reduce the cost of having multiple networked speakers around the home,” said Anthony Murray, Business Group SVP at CSR. “We are removing all the complexities of developing networked audio platforms by providing a full audio ecosystem that ‘just works’. Wireless audio is our passion, and we want to deliver incredible audio quality for the consumer, regardless of whether they are streaming their content from Wi-Fi or Bluetooth sources.”

According to Murray, the advancement that consumers will see is the seamless way they can introduce new audio devices into the home and the ease and flexibility with which they can send content to different speaker devices around the home. The audio will be synchronised and of very high quality, thanks to the aptX codec technology CSR is using.

VibeHub and VibePlayer Platforms

The VibePlayer platform’s low-power, cost-optimised design is ideal for creating affordable, portable, battery-powered wireless speakers, speaker docks and similar products. With the VibePlayer platform’s Wi-Fi, Bluetooth and Bluetooth Smart capabilities, manufacturers can create products that can be used as traditional Bluetooth wireless speaker docks, but also as part of a home Wi-Fi network, with the ability to play audio sent to it from DLNA digital media servers and VibeHub-based products.

The fully featured VibeHub platform can be used to build wireless docking systems, intelligent audio hubs, networked audio amplifiers and a wide range of other intelligent DLNA Certified products. The platform’s Bluetooth capabilities provide the important versatility of being able to stream audio from a wide assortment of mobile devices, making it easy for guests to play their favourite music over the home network when visiting without having to join the home Wi-Fi network.

Sonata

The new CSR Sonata networked media processor has been developed to support the needs of powerful, feature rich, networked home audio platforms such as the VibeHub platform. Its flexible architecture enables playback and forwarding of audio from many sources, including Bluetooth streaming devices, DLNA servers, Internet cloud-based services and USB and line-in inputs. In addition to handling the distribution of various types of content around the home concurrently, the Sonata processor enables the playback of identical content among multiple rooms.

The Sonata SoC is designed around a high-performance ARM Cortex-A9 CPU and Neon media accelerator that is more than capable of supporting not only the advanced networked audio software CSR provides but also a variety of additional features OEMs and ODMs can add to enable differentiation and customisation. It integrates Wi-Fi and Bluetooth stacks together with UPnP® and DLNA middleware to fully meet the processing demands of modern multi-room HD multimedia content distribution. A diverse range of I/O capabilities, HD graphics, touchscreen control and integrated ADCs and DACs round out the Sonata offering.

CSR provides extensive audio development kits for both platforms that include a range of software libraries with well-defined, high-level APIs. These kits enable manufacturers to develop software to their unique specifications, adding features like third-party audio processing algorithms or extra Internet radio and cloud services, as well as creating a customised look and feel for complete product differentiation.

A private, invitation-only demonstration of the VibeHub and VibePlayer platforms is taking place during the International CES 2013 show in the Springhill Suites, January 8-11. Attendees wishing to view the private demonstration should contact CSR for an invitation.
