Virtual Acoustics and Audio Engineering

Research

Our research spans a variety of audio engineering-related research topics. These include 3D audio capture and reproduction (including binaural audio, , cross-talk cancellation, Ambisonics, studies of the Head Related Transfer Function (HRTF)), loudspeaker and microphone arrays, multi-channel audio, other approaches to sound field control, human perception of sound in space, auralisation, combined audio-visual signal processing, and audio reproduction with listener tracking. It also includes other topics related to acoustical inverse problems such as sound source localisation, sound source separation and acoustical holography.

Measuring a HRTF in our large Anechoic Chamber

Compact-Mode HRTFs

We are developing a new representation of a HRTF that is more compact, leading to sparser HRTF measurement rigs, smaller HRTF datasets and more efficient binaural rendering.

VA system used in conjunction with Oticon hearing aids

Virtual Acoustics in Hearing Aid Research

Development of a low-cost and small-footprint virtual acoustics system for evaluating spatial hearing outcomes for hearing aid and cochlear implant users in clinic.

Use of machine learning for audio source separation

Audio Source Separation

Developing machine learning algorithms for audio source separation of stereo mixtures for upmixing applications to newer listening systems like 3D, ambisonics or binaural.

3D Audio with Listener Tracking

We are using advanced video tracking technologies to provide a personalised spatial audio experience that works independently of the listener position.

Compensated Amplitude Panning

Extension of panning methods, that uses head rotation tracking to produce surround sound with minimal speaker arrays.

Interactive Auralization

Auralise the acoustics of different enclosures allowing the listener to interact with the environment.
