3. Harmonic finder dialog

Figure 3.1 Click on thumbnail for full size image.

In figure 3.1, we see the dialog that appears when the search button next to the Code field in figure 2.1 is pressed. In this case we have chosen to look only for Harmonics that have a name starting with 'P', and we have chosen to show the harmonics. The simpler the Harmonic, the faster the computation time, so in this case 'Piped' will compute the fastest, then 'Piano2'.

Looking at Piano2, the tallest purple bar, on the left, is the fundamental/first harmonic (which in this case is also the strongest frequency). The next bar along represents the second harmonic, ie twice the fundamental frequency, the next bar along represents the third harmonic, ie three times the fundamental frequency and so on.

Looking at Piped, you can see that some harmonics are missing, actually this is showing even numbered harmonics, which is the opposite of what you'd expect to see in a closed pipe instrument, where all the harmonics are odd-numbered.
