This exercise calculates and displays the AMDF of a frame of speech from a designated speech file and implements a pitch detection algorithm based on using the AMDF on a frame-by-frame basis. This exercise can operate in a frame mode, displaying each analysis frame and its associated AMDF, or in a pitch detection mode. The file '3.4 AMDF Calculation.pdf' provides a User's Guide to this exercise.
