- We describe an algorithm to accurately estimate the fundamental frequency of harmonic sinusoids in a mixed voice recording environment using an aligned electronic score as a guide. Taking the pitch tracking results on individual voices prior to mixing as ground truth, we are able estimate the pitch of individual voices in a 4-part piece to within 50 cents of the correct pitch more than 90% of the time.
