S3A: Future Spatial Audio for an Immersive Listener Experience at Home

Qualitative evaluation of media device orchestration for immersive spatial audio reproduction (2018)
Journal Article

The challenge of installing and setting up dedicated spatial audio systems can make it difficult to deliver immersive listening experiences to the general public. However, the proliferation of smart mobile devices and the rise of the Internet of Thin...

An audio-visual system for object-based audio : from recording to listening (2018)
Journal Article

Object-based audio is an emerging representation for
audio content, where content is represented in a reproduction format-agnostic way and, thus, produced once for consumption on many different kinds of devices. This affords new opportunities for im... Read More about An audio-visual system for object-based audio : from recording to listening.

Object-based reverberation for spatial audio (2017)
Journal Article
Coleman, P., Franck, A., Jackson, P., Hughes, R., Remaggi, L., & Melchior, F. (2017). Object-based reverberation for spatial audio. Journal of the Audio Engineering Society, 65(1/2), 66-77. https://doi.org/10.17743/jaes.2016.0059

Object-based audio is gaining momentum as a means for future audio content to be more immersive, interactive, and accessible. Recent standardization developments make recommendations for object formats; however, the capture, production, and reproduct... Read More about Object-based reverberation for spatial audio.

Evaluating a distortion-weighted glimpsing metric for predicting binaural speech intelligibility in rooms (2016)
Journal Article

A distortion-weighted glimpse proportion metric (BiDWGP) for predicting binaural speech intelligibility were evaluated in simulated anechoic and reverberant conditions, with and without a noise masker. The predictive performance of BiDWGP was compare... Read More about Evaluating a distortion-weighted glimpsing metric for predicting binaural speech intelligibility in rooms.

Dual frequency band amplitude panning for multichannel audio systems
Presentation / Conference
Hughes, R., Franck, A., Cox, T., Shirley, B., & Fazi, F. Dual frequency band amplitude panning for multichannel audio systems. Presented at 2018 AES International Conference on Spatial Reproduction - Aesthetics and Science, Tokyo, Japan

Panning laws for multi-loudspeaker setups, for example vector base amplitude panning, are typically derived based
on either low or high frequency assumptions. It is well known, however, that auditory cues for both localization and loudness differ at... Read More about Dual frequency band amplitude panning for multichannel audio systems.

The room-in-room effect and its influence on perceived room size in spatial audio reproduction
Presentation / Conference
Hughes, R., Cox, T., Shirley, B., & Power, P. The room-in-room effect and its influence on perceived room size in spatial audio reproduction. Presented at 141st Convention of the Audio Engineering Society, Los Angeles, USA

In spatial audio it can be desirable to give the impression of a target space (e.g. a church). Often the reproduction environment is assumed acoustically dead; in practice most listening spaces (e.g. domestic living rooms) introduce significant refle...
