[data,Fs]=audioread('1st pipe sound.m4a');
N=length(data);
ts=1/Fs;
t=0:ts:N*ts-ts;
F=0:Fs/N:Fs-Fs/N;
FFT_data=fft(data);
subplot(1,2,1)
plot(t,data);
xlabel('time[sec]')
ylabel('Amplitude')
title('1st pipe sound')
subplot(1,2,2)
plot(F,abs(FFT_data)/N);
xlabel('Frequency')
ylabel('Amplitude')
title('1st sound fft result')
