Higher Order Ambisonic signal (HOA) near-field effect (NFE) proximity transformer.
HoaNFProx.ar(in, order)
Arguments:
in |
The input signal. |
order |
Ambisonic order. |
Discussion:
HoaNFProx translates an input HOA signal where refRadius = AtkHoa.refRadius
to refRadius = inf
.
This transform offers an HOA equivalent to FoaProximity where distance = AtkHoa.refRadius
, in the first order case.
NOTE: This operation may be used to decode signals encoded as HOA with NFE to FOA or third party Ambisonic signal sets.
WARNING: The near-field effect proximity transformer is inherently numerically unstable and requires the use of signal pre-conditioned input to avoid overflow. In many cases, the use of
HoaNFCtrl is advised, instead.
