Matlab Code for audio decoder of morse code

ECE6342_morse_code_sound.wav is a mono (1-channel) 11,025 samples per sec, 16-bits per sample, WAV file. There is a Morse code signal within the audio file. You should be able to hear it in the background if you listen for it, but it is not very audible (able to be heard).

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,
