Log Harmonic Product Spectrum

Plots a sequence of frames of both HPS and LHPS

Speech processing designates a team consisting of Prof. Lawrence Rabiner (Rutgers University and University of California, Santa Barbara), Prof. Ronald Schafer (Stanford University), Kirty Vedula and Siva Yedithi (Rutgers University). This exercise is one of a set of speech processing exercises that are intended to supplement the teaching material in the textbook “Theory and Applications of Digital Speech Processing” by L R Rabiner and R W Schafer.
This MATLAB exercise plots a sequence of frames of both the Harmonic Product Spectrum (HPS) and the Log-Harmonic Product Spectrum (LHPS), and displays the resulting spectrums in the form of a waterfall plot.
