Pitch Tracking of Acoustic Signals based on Average Squared Mean Difference Function
Roudra Chakraborty, Debapriya Sengupta, Sagnik Sinha
In this paper, a method of pitch tracking based on variance minimization of locally periodic subsamples of an acoustic signal is presented. Replicates along the length of the perio…
