Oh wow, I forgot the difference between my arms and my elbows! Thanks Aaron for pointing that out. I have played quite a bit with the ATK before, indeed the transformation tools are really great. I downloaded the ADT this last weekend have been playing around with the examples in Octave - yet to l

Hello Aaron, Thanks for the Ambisonic Toolkit (ATK) call out. Replying to this: A practical problem is that forward NFC filters have infinite gain at DC. > Jerome Daniel's solution is to have a reference decoding distance for > Ambisonic program material, say 1

Re: [Sursound] Anyone had experience with AllRAD decoding to physical loudspeakers?

Thanks so much Aaron! I have seen the ambisonic toolkit around but haven't played with it too much. I will look into it and compare the values you get, to the values I've got. If I run into issues I will definitely contact you. The speakers are relatively equidistant but I definitely think there ar

Wow! I'm so extremely grateful for all this information everyone. Thank you for taking the time out to inform me and providing some really cool resources to look at. Looking forward to exploring the Faust and SHARC integration as I was not aware you were able to do this. Gives me a good excuse to

Better references for compiling FAUST to SHARC are https://wiki.analog.com/resources/tools-software/sharc-audio-module/faust https://youtu.be/iUB8ru-76qw It might be easier for you to experiment with the decoders running on a regular computer, then commit to the DSP board when you have config

Re: [Sursound] Anyone had experience with AllRAD decoding to physical loudspeakers?

Hi Sean, Are all the speakers at the same distance? If not, the sound will be drawn to the closest one due to the precedence effect. So you need to insert delays and adjust the level. For small arrays, near field compensation is also important. My MATLAB/Octave toolbox implements AllRAD (in fact,

Re: [Sursound] Anyone had experience with AllRAD decoding to physical loudspeakers?

Thanks for the reply Florian. Yes, was aware of the imaginary loudspeakers. The algorithm I've implemented does take this into account. Although maybe some further tweaking is necessary. Currently it adds these imaginary loudspeakers into the convex hull algorithm if there are top and bottom louds

Hey everyone! Hope all are doing well. Want to know if anyone in this group has experience with AllRAD decoding to physical loudspeakers? I'm asking for some advice, or guidance, on how to best optimize this decoding approach for multiple loudspeakers in different arrangements. My current listenin
