I have a .wav file. I've obtained and plot the signal for a segment of between x(670000:689000). The plot shows about 2 different notes in the segment. How do I plot and determine the frequency of each notes? Below is my codes:
clear all; close all; clc;
[x,fs] = audioread('Bass.wav');
x = x(670000:689000,:);
sound(x,fs);
t=0:1/fs:(length(x)-1)/fs;
plot(t,x);
n=length(x)-1;
f=0:fs/n:fs;
wavefft=abs(fft(x));
plot(f,wavefft);
