aspcol.soundfieldestimation.krr_moving_mic(p, pos, pos_eval, sequence, samplerate, c, reg_param, kernel_func=None, kernel_args=[], return_params=False)

Estimates the RIR at evaluation positions using data from a moving microphone using Bayesian inference of an infinite sequence of spherical harmonics

Parameters:

• p (ndarray of shape (N)) – sound pressure for each sample of the moving microphone

• pos (ndarray of shape (N, 3)) – position of the trajectory for each sample

• pos_eval (ndarray of shape (num_eval, 3)) – positions of the evaluation points

• sequence (ndarray of shape (seq_len) or (1, seq_len)) – the training signal used for the measurements

• samplerate (int)

• c (float) – speed of sound

• reg_param (float) – regularization parameter
