Audio signal processing

We develop digitally-controlled audio processing platforms that enable high-performance multi-mode active noise cancelling, digitally-configurable occlusion control and advanced situational awareness. Our platforms overcome many of the limitations of conventional analog methods, as well as the power and patent challenges of pure digital designs.

Each platform enables digitally-controlled feedback, feed-forward or hybrid active noise cancellation, and when operated with appropriately designed headphone acoustics is capable of removing almost all of the ambient background noise surrounding the listener.

Audio compensation filters are incorporated within each platform's design to compensate for the effect of feedback ANC on the faithful reproduction of program audio, as well as to shape the headphone's receiving response. Furthermore, each platform incorporates low-latency, binaural talk-through filters to enable a natural open-ear awareness mode that can be configured to render a fully-immersive augmented listening experience.

Our platforms enable a new generation of smart, software-controlled headphones and hearables, which can be made fully responsive to both the wearer's use-case and ambient sound conditions.

Supervisory control software

Our supervisory control software provides the means through which intelligent control, monitoring, supervision, and environmental adaptation can be deployed in noise cancelling products. Through the deployment of this technology, customers are able to significantly enhance the wearer experience of their products and resolve many of the common issues associated with active noise cancellation systems more generally.

  • Smartaware™

    Rather than limit headphones to a fixed set of modes, Smartaware provides the wearer with the ability to configure their listening experience. Put simply, Smartaware allows users to independently control how much of the ambient sound conditions they want to hear. To enable this technology, the headphone must firstly be capable of sup

  • Auto ANC®

    A layer of ‘intelligence’ that allows the headphone to autonomously configure its electroacoustic state in accord with changing acoustic environments. Noise cancelling generally operates in one fixed mode, retaining the same filter settings and performance irrespective of changes in the operator’s ambient sound environment. This me
