Figure 4From: Joint DOA and multi-pitch estimation based on subspace techniquesExample of cost functions for two synthetic sources having three harmonic each, N = 64 and M = 8. The true fundamental frequency of ω1 = 252.123 and ω2 = 300.321 having DOA θ1 = -43.23° and θ2 = 70°, respectively.Back to article page
