We have splitted the piano scale time spectrum to extract each note and be able to identify the main frequency of each of them.
It is possible to observe that the main frequency of the spectrum that determines the note does not always correspond to the highest power peak.
One of our duties in this project is to be able to detect correctly the main frequency whether it is the frequency component with the largest amplitude or not. The FIRST PEAK is the one that identifies the note, the rest are harmonics.
In this project we will identify at least all the notes in the 3rd, 4th and 5th scales.
