Yup, all good advice. Not a direct answer to the question, but a possibly relevant new convolution reverb approach: http://www.blueripplesound.com/story/new-toa-shaped-convolution-reverb Depending on how it's configured it can be a bit of a CPU hog, but worth it IMHO... --Richard > -Origina

Hi there! Blue Ripple Sound are wondering about changing their TOA plugins from FuMa to SN3D (ACN), see http://www.blueripplesound.com/story/consultation-sn3d. Does anyone have strong feelings on this? Opinions, rants and raves appreciated, but I'd like to avoid kicking off another format d

Re: [Sursound] B-Format to Auro 3D

I'm not sure what you're asking. Is it how to set the track channel count in Reaper? We have guides on this in the TOA docs, but from your email I'm guessing you're using the HS plugins. Please let me know about else like this that's unclear - it's always good to know what to add to our docs!

Re: [Sursound] B-Format to Auro 3D

Our (Blue Ripple Sound's) "TOA Decoding" plugins include decoders for the Auro-3D layouts, so if you're prepared to work in Reaper or suchlike I'd suggest one of these two signal paths. There are other options, but these seem to give consistently good results: 1. B-Format -> TOA Harpex Upsample

Re: [Sursound] New Ambisonic VST Plugins - follow up Question to Fons

Of course, you're quite right as usual! In crude terms, a speaker array with a small number of speakers only has a few degrees of freedom with which to reconstruct spherical harmonics. (Rapture3D will manage this for you.) However, the higher order harmonics also have a range of other uses in freq

I basically agree with all of this - I just don't think it's that big of an issue in practice. We don't generally ask engineers to provide their stereo mixes twice for -3dB and -6dB pan laws, though arguably we should. [Okay, tenuous parallel.] HOWEVER, we want these plugin libraries to do what fo

Re: [Sursound] higher order ambisonics over 8 to 10 loudspeakers

IMHO it depends on how you're generating your decoder - using a fairly "evenly" spaced speaker layout that's roughly consistent with the order means that all the matrices in the maths end up well-behaved if you do a fairly simple matrix inversion. HOWEVER, it isn't obvious that this is the best way

Re: [Sursound] Can anyone explain this ?

Yep - I concur. The Rapture3D HCTC decoders do similar things, particularly for similarly band-limited stuff - though this is a rather impressive example! Weirdly, I sometimes find this stuff works better on my left side than my right. Is that just me? Best wishes, --Richard -Original Mes
