I'm building a program to detect the notes from an audio file that contains 5 chords, each containing 3/4 notes. This is my code:
[y,Fs] = audioread('sample1_pm17025.wav');
sg = 400;
ov = 300;
I assume that the five different sections are chords, however, within those sections how do I actually determine the frequency of the notes? In the first section every line is very close together and very white, in the later sections that seems to be a little bit of a split between notes but how would I know, in the first chord, what the 3/4 notes correspond to in terms of frequency?
