aspcol.kernelinterpolation.soundfield_interpolation_fir(to_points, from_points, ir_len, reg_param, num_freq, spatial_dims, samplerate, c)

Convenience function for calculating the time domain causal FIR interpolation filter from a set of points to another set of points.

Parameters:

• to_points (ndarray of shape (num_to_points, spatial_dims))

• from_points (ndarray of shape (num_from_points, spatial_dims))

• ir_len (int) – length of the impulse response

• reg_param (float)

• num_freq (int)

• spatial_dims (int)

• samplerate (int)

• c (float) – speed of sound

Return type:

ndarray of shape (ir_len, num_to_points, num_from_points)
