Figure 4From: Joint estimation of pitch and direction of arrival: improving robustness and accuracy for multi-speaker scenariosHarmonic sieve with four different pitch values f 0 up to the fourth harmonic ( P =4; black lines). The exemplary harmonic signal consists of equally spaced triangles. Best estimation results would be achieved with example 3 (f0=200 Hz) where the pitch of the signal and harmonic sieve match.Back to article page
