Higher Order Ambisonic (HOA) "by degree" distance radial filter

Description

Higher Order Ambisonic signal (HOA) near-field effect (NFE), distance radial filter by Associated Legendre degree (ℓ).

NOTE: As a utility, DegreeDist supports NFE radial filtering and transformation. In most cases users will not directly use this filter. Instead, HoaNFDist profides the near-field effect distance transform operation on input HOA signals.

Class Methods

.ar

Arguments:

in

The input signal.

radius

The decoding radius in meters.

degree

Associated Legendre degree (ℓ)

Discussion:

DegreeDist is implemented as a cascade of SOS and FOS filters, where coefficients are calculated by NFECoeffs: -dist.
