Write a Matlab program performing the following operations:
1. Use the following parametrs values:
window_length = 128;
window type – hamming
overleap = 0 samples (no overleap between windows)
2. Read the rainm1.wav file as an input signal
3. Plot the time-domain waveform of input signal
4. Divide the signal into frames of length = 128 samples each. Multiply each frame by the
Hamming window and write the windowed frames into a matrix thus, that each row of this
matrix contains a single frame.
5. Analyse the signal by calculating the fft and amplitude spectrum of each frame.
