Write a Matlab program to analyze the wav file and determine the narrow range of frequencies occupied by the morse code sounds (use DFT analysis?). See below. Then apply a filter to separate the Morse code sound into a separate file and to separate the music into a separate file.
Write out the separated Morse code and the separated music to separate wav files titled morse.wav and music.wav,
