Overtone Slider<\/h2>\n

The Frequency Filter enables you to listen to the individual harmonics (or overtones) in a
\n recording, and the Overtone Slider is a tool that allows you to easily count the overtones and
\n to see which note or frequency they correspond to, and to have a visual reference for a
\n specific note or frequency.<\/p>\n

To use Overtone Sliders, first click on Settings Profiles<\/span> on the
\n toolbar and select the Single Row Toolbar<\/strong><\/span> profile. This will
\n introduce a few new items on the toolbar. The two that we are interested in now are the edit
\n field for the number of overtone sliders, and the menu button to set the snap mode:<\/p>\n

Each slider has a fundamental frequency and could be interpreted as a musical note, and it
\n can show the over- and undertones corresponding to this frequency.<\/p>\n

The Snap Mode<\/strong><\/span> determines what happens when you move the
\n slider. If snapping is off, it will move freely. If snapping is enabled, the slider will snap
\n to the nearest musical note on the piano, or the nearest peak in the spectrum. Snapping to a
\n musical note would be used if you want to set the note that you want to sing, and snapping to
\n the spectral peak would allow you to measure what you actually sung. <\/p>\n

Set the Number of Sliders<\/span> edit field on the toolbar to
\n “1”. This will add a single slider overlay on the screen. Click on the red line of the slider
\n and drag it up and down. <\/p>\n

Click on the icon of the Snap mode<\/span> button to enable snapping. Then
\n click on the down arrow on the right side of the button to open the button menu and switch
\n between snapping to musical notes and spectral peaks. Observe how these actions change the
\n behaviour of the slider line when you move it up and down.<\/p>\n

Now position the green time cursor line in the middle of Note 5 (at around 8.5 s) to set
\n the spectrum to that position. Then move the slider on the Short-term view to align with the
\n lowest harmonic. Now point at the right upward facing triangle of the slider and drag it all
\n the way up. Your Short-term view should now look something like this:<\/p>\n

<\/p>\n

You can scroll down the Frequency Scale and zoom it slightly until you see enough detail of the Overtone Slider. The slider gives you a theoretical view of the overtones that belong to a particular sound. The labels of the slider lines show the number of the harmonic, its music note, and its frequency. The underlying Spectrogram shows the harmonics that are actually present in the recording. Click on the labels of the Overtone Slider and move the mouse up and down while holding the mouse button to hear the overtone scale belonging to the current fundamental pitch. Compare this to the actual overtones in the sound that you could hear with the Frequency Filter.<\/p>\n<\/div>\n
