Audio Amplifiers

These are electronic amplifiers that amplify low power audio signals, in the 20Hz to 20kHz band, to a level suitable for driving a loudspeaker or headset.


Integrate all the audio functionality such as signal routing, mixing, converting and amplifying onto a single audio centric device to give consistent high definition audio quality across different applications and tiers.

MEMS Microphones

Micro-electro-mechanical systems (MEMS) microphones offer a unique combination of high performance and compact form factor to enable crystal clear audio capture. The close tolerance sensitivity makes them ideal for multi-microphone applications such as noise cancellation and speakerphone.

Power Management

Power management integrated circuits (PMICs) intelligently manage and optimise the use of power within the system architecture to maximise battery life in portable devices.


The selection of advanced audio algorithms allows customers to select differentiating features for their products from noise cancellation to sound enhancement.


Wolfson provides leading application-specific HD Audio solutions for tablets.

Wolfson's leading-edge Audio Hubs and HD Audio processors, along with its MEMS microphone and power management technologies are at the heart of tablet architectures and enable a richer user experience. Wolfson's Audio Hubs manage, convert and process a diverse array of analogue and digital audio sources, transforming the capability and performance of portable multimedia applications, including tablets.

Wolfson's family of audio solutions has been further enhanced with the HD Audio processor, integrating full Tx and Rx noise reduction and Wolfson's adaptive Ambient Noise Cancellation (ANC) technology, as well as featuring a multi-core programmable Digital Signal Processor (DSP) for audio processing.

As noise reduction and advanced audio processing becomes an accepted part of a tablet there is a need for multiple microphones. Wolfson's compact and high performance MEMS microphones are ideal for these solutions.
