I’ve become confused with the options for normalization in the HOA patchers of spat5. There is an option for both FuMa and MaxN which has confused me.
In the help patch for spat5.hoa.converter~ it states “FuMa and MaxN are almost the same. The only difference is a sqrt(2) = 3dB gain on the Wchannel”. However, I am not certain that this is correct.
Is not Classic Gerzon – FuMa actually the following?
W: 1/sqrt(2); 3dB
X: 1: 0dB
Y: 1; 0dB
Z: 1; 0dB
Where as maxN is the following:
W: 1; 0dB
X: 1; 0dB
Y: 1; 0dB
Z: 1; 0dB
If this is the case, isn’t option listed as MaxN is actually maxN?
Thanks,
Scott

Hi Scott,
Sorry for the late reply.
I’m not quite sure to understand your question/problem.
“Is not Classic Gerzon – FuMa actually the following?
W: 1/sqrt(2); 3dB
X: 1: 0dB
Y: 1; 0dB
Z: 1; 0dB
Where as maxN is the following:
W: 1; 0dB
X: 1; 0dB
Y: 1; 0dB
Z: 1; 0dB”
–> Yes, I agree with that.
“If this is the case, isn’t option listed as MaxN is actually maxN?”
–> What do you mean ? Do you discriminate between MaxN (upper case) and maxN (lower case) ??
I might be missing something, but the equations implemented in spat5.hoa.converter~ seem correct to me.
Best,
T.
