aspcol.sphericalharmonics.shd_min_order

aspcol.sphericalharmonics.shd_min_order(wave_num, radius)

Returns the minimum order of the spherical harmonics that should be used for a given wavenumber and radius

Here according to the definition in Katzberg et al., Spherical harmonic representation for dynamic sound-field measurements

Parameters:
  • wave_num (ndarray of shape (num_freqs))

  • radius (float) – represents r_max in the Katzberg paper

Returns:

M_f – contains an integer which is the minimum order of the spherical harmonics

Return type:

ndarray of shape (num_freqs)
