Big Fish Semiconductor’s U2 5.2 Audio SoC enters mass production with Dolphin Design’s Audio IPs

Our brand new U2 5.2 Audio SoC is a game-changer in the TWS Bluetooth headset market with its ultra-low power consumption. But none of this would have been possible without Dolphin Design's Audio IP. It has a high-fidelity ADC that combines superior audio performance with a small footprint and ultra-low power consumption, which is exactly what we, at Big Fish Semiconductor, were looking for. We are delighted with this partnership with Dolphin Design, which will continue for our future SoC developments.

Download our white paper on Voice Activity Detection (VAD)

More than ever before, attention to power consumption is paramount when developing new products. In this environment, voice activity detection has a major role to play in any new voice-controlled system. The main objective of VAD is to lower power consumption, saving on computation or data processing by deactivating part of the SoC when no speech patterns are detected.
Markets like home assistants and telecommunications can greatly benefit from this feature as the
always-on mode is not exactly suitable for wireless products or when privacy is a concern.
