Audio and acoustic technologies

audio and acoustic technologies 2 hero

We have deep research and development capability in audio and acoustic engineering, digital signal processing and implementation on field-programmable gate array (FPGA) and digital signal processing (DSP) platforms.

Our audio engineering team has been developing world-leading acoustic solutions for over 25 years.

We have the expertise to produce customised DSP algorithms delivered on a platform of your choice.

Technology developed by us has been licensed internationally and we have carried out numerous research contracts for local and international high-tech organisations.

Our science capability has been proven through numerous publications coupled with our practical experience in analogue electronics and digital signal processing.

As well as developing acoustic and audio systems for customers, we have licensed our in-house developed technology, giving us a broad understanding of the requirements and challenges involved in commercial implementations.

 

Our areas of expertise

Spatial sound systems utilising:

• Diffraction (boundary element) modelling and diffraction-compensated beamforming design for non-spherical microphone arrays
• Signal processing algorithms for virtual reality (soundbars, crosstalk cancellers)

Microphone array systems, incorporating:

• Design using digital micro-electro-mechanical systems (MEMS) microphones and field programmable gate array (FPGA) processing
• Loudspeaker array processing
• Proof-of-concept demonstrators

Audio processing algorithms for music applications

Our capability and experience in audio signal processing is recognised as world-class.

Case study

Meyer Sound

Meyer case studyBusiness opportunity
Improvements to electronic sound systems for enhancing concert hall acoustics which produced low reverberation time gain and unnatural sound.

What we did
We developed a novel enhancement system based on the idea of a coupled room using digital reverberation processing that provided significant increases in reverberation time gain with reduced colouration.

Result
We obtained three international patents, developed a prototype and licensed the technology to Meyer Sound.
