Higher Order Ambisonic (HOA) "by degree" radial filtering coefficients

Source: NFECoeffs.sc

Higher Order Ambisonic (HOA) "by degree" radial filtering coefficients, returned for realization by FOS and SOS cascade.

NOTE: In most cases, users will use the high level near-field effect (NFE) pseudo-UGens: HoaNFProx, HoaNFDist, HoaNFCtrl.

Create a new instance.

degree |
Associated Legendre degree (ℓ). |

Return Associated Legendre degree (ℓ).

Return number of FOS required for cascade.

Return number of SOS required for cascade.

Return a dictionary of near-field effect proximity radial filtering coefficients. See Coefficient Dictionary below.

radius |
Radius, in meters. |

sampleRate |
Sample rate, in Hz. |

speedOfSound |
Speed of sound, in meters per second. |

Return a dictionary of near-field effect distance radial filtering coefficients. See Coefficient Dictionary below.

radius |
Radius, in meters. |

sampleRate |
Sample rate, in Hz. |

speedOfSound |
Speed of sound, in meters per second. |

Return a dictionary of near-field effect control radial filtering coefficients. See Coefficient Dictionary below.

encRadius |
Encoding radius, in meters. |

decRadius |
Decoding radius, in meters. |

sampleRate |
Sample rate, in Hz. |

speedOfSound |
Speed of sound, in meters per second. |

FOS and SOS coefficients are returned as rank two arrays of coefficients, available via the IdentityDictionary `\sos`

and `\fos`

keys. Additionally, a a normalizing scalar is also returned via the `\g`

key.
