aspcol.soundfieldcontrol.spatial_cov_delta

aspcol.soundfieldcontrol.spatial_cov_delta(ir, filt_len)

Calculates the spatial covariance matrices as if the input signal is a delta ir is the default shape given by arrays.paths (num_ls, num_mics, ir_len)

Multiplies result with ir_len, because corr_matrix divides with the number of samples,

but here that shouldn’t be done to keep the correct scaling, as the values are just the ir and not filtered samples

Returns:

spatial_covariance

Return type:

ndarray of size (num_ls*filt_len, num_ls*filt_len)
