So my thesis is all signed off and I should hopefully upload it (probably to ResearchGate) some time soon. As a teaser, here are some of the main points covered:
- A review of spatial hearing, plus reviews of some important binaural and vector models for prediction.
- A review of Ambisonics and Higher Order Ambisonics (HOA).
- Results of three perceptual experiments for Ambisonics and HOA at off-centre positions.
- Comparison of the binaural models and Gerzon’s energy vector to the perceptual results.
- An extension to Gerzon’s energy vector to include elements of the precedence effect for more accurate predictions at off-centre positions.
Last year I was lucky enough to take part in a radio show about sound and space directed by Rachel Ní Chuinn and played on RTE radio. It was called ‘The Shape of Sounds to Come’ and you can listen to it by clicking here.
It features the renowned Alvin Lucier, as well as the music and thoughts of several other SARC staff and students on sound and how we interact with it. I give a brief explanation of some basics of acoustics. It’s really the contributions of others that contain the most interesting sections.
It’s definitely worth a listen. It doesn’t deal with Spatial Audio in the realm of technology. Instead, it’s more about how sound the sound around us everyday can influence in other ways, such as in architectural acoustics.
The paper I presented at the Auralization and Ambisonics symposium in Berlin last April has been published in Acta Acustica united with Acustica. There are also 9 other papers from the conference that were chosen and definitely all are worth looking at. You can see the table of contents for the new issue here.
The proceedings of the joint Ambisonics and Auralization symposium has been published as a book today. You can get it here. It’s definitely worth checking out because there were lots of interesting works presented.
Ten of the papers are missing (including my own) because they’ll be out in the autumn in a special issue of the journal ‘Acta Acustica united with Acustica’.
I’ll be at the Ambisonics Symposium (joint with the Auralization symposium) in Berlin this week (3rd-5th April). The program is here and it looks like it’ll be really interesting.
I’ll be presenting a paper titled “Off-Centre Localisation Performance of Ambisonics and HOA for Large and Small Loudspeaker Array Radii” on the 5th. I’ll post a link to the paper once it’s up on the TU Berlin website, which should hopefully be in the next couple of days.
If you happen to be going then please get in touch because I’d love to chat.
The proceedings of DAFx13 have gone up on their website so you can read my paper if you’re interested in it.
Download it here.
View all the papers presented during the week here.
I’ll be presenting next Thursday at DAFx13 in Maynooth, Ireland. The paper details the results of an experiment I carried out in February about localisation at off-centre positions. It’s titled:
Perceptual Investigation of Image Placement with Ambisonics for Non-Centred Listeners
If you’re also going to DAFx then please get in touch, I’d look forward to chatting.
I’ll try to post the paper some time next week after it’s been presented.
