aspcol.soundfieldcontrol.rir_to_szc_cov

aspcol.soundfieldcontrol.rir_to_szc_cov(rir, ctrlfilt_len)

Takes room impulse responses and computes a spatial covariance matrix for sound zone control

Parameters:

rir (ndarray of shape (num_ls, num_mic, ir_len)) – turns it into the time domain sound zone control spatial covariance matrix made up of the blocks R_l1l2 = H_l1^T H_l2, where H_l is a convolution matrix with RIRs associated with loudspeaker l

Returns:

szc_cov

Return type:

ndarray of shape (num_ls*ctrlfilt_len, num_ls*ctrlfilt_len)

Notes

This should probably be equivalent to spatial_cov_delta. Better write a test and check.
