Dialog Semiconductor Demonstrates Bluetooth Low Energy True Wireless Stereo Solution at Bluetooth World 2018

September 19 2018, 03:00
Claiming an industry-first technology to address the challenges associated with power consumption in true wireless stereo systems, Dialog Semiconductor introduced an audio over Bluetooth low energy proof of concept running on its widely adopted SmartBond SoC’s, the first implementation to solely make use of Bluetooth low energy. This technology, which Dialog is unveiling at Bluetooth World 2018 (September 18-19) in Santa Clara, allows for best-in-class audio synchronization between left and right channels, and addresses the challenges associated with power consumption.
 

As demand for wireless audio has continued to increase, it has become apparent that True Wireless Stereo (TWS) systems, featuring no wires between earbuds, have emerged as a clear favorite for both consumer and professional use. However, these systems come with their own set of development challenges. Existing implementations make use of a combination of classic Bluetooth and Bluetooth low energy technology for sound distribution between left and right channels, often resulting in imbalanced battery usage and limited battery life for the products.

Dialog Semiconductor is using this year’s Bluetooth World event in Santa Clara, California to demonstrate Stereo High Fidelity (HiFi) quality audio streaming over Bluetooth low energy technology, enabling an improved implementation of true wireless stereo audio streaming. The proof of concept implementation was showcased to Bluetooth SIG Associate members at the event.

Dialog has developed the new audio over Bluetooth low energy proof of concept running on its widely adopted SmartBond SoC’s. Using only Bluetooth low energy. the implementation allows for best-in-class audio synchronization between left and right channels, together with the low power consumption.
 

"There is a clear demand from end-users for True Wireless Stereo audio, particularly in environments where even a single wire between earbuds can prove cumbersome and frustrating,” says Sean McGrath, Senior VP & GM of Dialog Semiconductor’s Connectivity Business Group. “This proof of concept demonstrates Bluetooth low energy’s potential to deliver the solution developers need, while overcoming the limitations of existing technology that have traditionally held devices back from their true potential.”

“By solving the issues of power consumption and synchronization, we are showing how Bluetooth low energy could address two of the biggest complaints from True Wireless audio users. Manufacturers would have the ability to deliver True Wireless Stereo audio products that can simultaneously stream HiFi quality audio while delivering long lasting battery life for their products in the consumer and professional wireless audio market,” adds McGrath.
