This program can detect pitches from mp3 files and its purpose is to convert time - amplitude data file into time - pitch file
SciPy, NumPy, matplotlib.pyplot
variables: n, k, timeList, amplitudeList(ampList) n: Number of time intervals needed for each FFT k: Range of frequency to focus on timeList&litudeList: csv file format(loaded from Sonic Visualizer)
Sonic Visualizer's time data needs initial calibration
