SVD-PHAT localizes multiple sound sources more accurately than discrete SRP-PHAT by using multiple scans and orthogonal subspace projections, reducing RMSE by up to 0.0395 radians while keeping low complexity.
Let us define the vector Xi,j ∈ C(N/2+1)× 1 for the microphone pair (i, j)∈P that holds the phase normalized cross-correlation coefficients for all bi ns k∈ {0, 1
