DegreeCtrl
Extension
ExtensionHigher Order Ambisonic (HOA) "by degree" control radial filter
Description
Higher Order Ambisonic signal (HOA) near-field effect (NFE), control radial filter by Associated Legendre degree (ℓ).
NOTE: As a utility, DegreeCtrl supports NFE radial filtering and transformation. In most cases users will not directly use this filter. Instead, HoaNFCtrl profides the near-field effect distance transform operation on input HOA signals.
Class Methods
.ar
Arguments:
| in |
The input signal. |
| encRadius |
The encoding radius in meters. |
| decRadius |
The decoding radius in meters. |
| degree |
Associated Legendre degree (ℓ) |
Discussion:
DegreeCtrl is implemented as a cascade of SOS and FOS filters, where coefficients are calculated by NFECoeffs: -ctrl.
