I’ve just released a new first-order Ambisonic panner over on my new website. It’s absolutely free and you can read more about it here.
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.
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.
I’ve not posted any music in quite a while so here’s the 10th song/demo that I was working late last year (the others can be heard here). I never got round to recording the vocals to it and had a bit of free time a few weekends ago so I thought I might as well do it while I had the time.
So we’re only at March and I think I’ve already let my “update this blog at least one every 2 weeks” target slip… Oh well, I’ll have to try harder!
I’ve been busy working on a conference paper with the main conclusions of my listening experiment. It’s limited it 6 pages in length and it’s actually quite hard to fit everything into that sort of space.
SARCoder – Ambisonic Decoder
I’m going to try get working on the decoder VST again. It’s really stalled and I need to get back to it – there’s not much point having two encoder VSTs without a decoder (although there are others out there). The first version I get released will probably be pretty basic but once I can get it into a good form I’ll be able to add new features more easily.
