Binaural and Head Tracking Paper

The Audio Engineering Society has put up the papers for the upcoming 140th AES Convention in Paris. You can download my paper here.

The paper was done in collaboration with the Conservatoire national supérieur de musique et de danse de Paris, who will also have some very interesting demos on a stand at the Convention.

It’s a study comparing perception of sound source stability between 1- and 5-source sound scenes for different levels of latency. I’ll be presenting it on the last day of the convention in the Immersive Audio section.

New Paper: Energy Vector for Off-Centre Positions

I’ve had a paper accepted to the Journal of the Audio Engineering Society based on some of the work from my thesis. It was published last week.

The title is “Extended Energy Vector Prediction of Ambisonically Reproduced Image Direction at Off-Centre Listening Positions“. It presents an extension to the energy vector (rE) of Gerzon used in the Ambisonics literature. The extension allows for better prediction of localisation for listeners who aren’t equidistant from all loudspeakers.

It basically adds elements of the precedence effect (or “Law of the First Wavefront”) to the energy vector. This means it can now be used to predict time-delay panning, in addition to amplitude panning.

You can download the paper in the AES e-Library:

I’ll be posting some supplementary data and tools in the near future. There’ll be some examples of the usage and some listening area localisation maps.
