Electronics

We develop hybrid analog-digital audio signal processing platforms that enable advanced, digitally programmable noise cancelling, audio equalisation and open-ear listening. These platforms overcome the limitations of traditional discrete analog component-based noise cancelling solutions as well as the power and patent challenges of pure, mixed-signal designs. Our platforms enable a new generation of smart, software-controlled headphones that are responsive to the wearer's use-case and ambient sound conditions.

Each platform supports both feedback and feed-forward methods of noise cancellation and, when combined with a suitable acoustic platform, these control methods can be employed uniquely or in a hybrid configuration to substantially reduce unwanted noise. Audio compensation is implemented separately and may be configured to mitigate the effects of feedback active noise cancellation, as well as to shape the connected acoustic system’s audio frequency response.

In addition to audio compensation, zero-latency binaural talk-through enables natural ‘open-ear’ listening, which can be further enhanced by mixing in other audio sources to provide an augmented listening experience.

  • Smart Aware

    Rather than limit headphones to a fixed set of modes, Smart Aware provides the headphone wearer with the ability to configure their listening configuration to suit. Put simply, Smart Aware allows the wearer to independently control how much of the ambient sound environment is heard in combination with their selected program audio.
