On this dialog you can select range, type and orientation of the frequency scale and adjust the appearance and behaviour of the Overtone Sliders. Most of those settings can also be found on the toolbar.
Scale Range
This is the lowest and highest note or the lowest and highest frequency that are displayed the piano and analyzer views.
Frequency Display
This determines if the frequency scale is linear or logarithmic.

The image illustrates the difference between the linear and logarithmic frequency scale. Both sides show a frequency range of 16 Hz to 2093 Hz.
When the scale is linear, consecutive overtones have the same distance on the screen, but the piano keys get wider for higher frequencies. This shows that the higher piano keys cover a much wider frequency range than the lower keys.
With the logarithmic frequency scale, all piano keys have the same size. Higher harmonics are spaced more and more closely than the lower ones. The logarithmic scale represents how the ear perceives pitch. Towards the lower end of the scale, we can distinguish very small frequencies and hear them as different notes. On the upper end of the scale, each note covers a much wider frequency range. The logarithmic scale is therefore more suitable for analyzing music, as it shows much more detail in the lower note range.
Orientation
This simply determines wether the frequency scale is aligned horizontally or vertically. The other axis is time for the spectrogram, or intensity for the spectrum.
Overtone Sliders
These settings control the number and the appearance of the displayed overtones. There are only two settings that are not found on the toolbar:
Draw tempered notes
This enables or disables the thin grey lines shown in the background of the analyzer view. They correspond to the frequencies of the tones on the piano. When snapping to tempered notes is enabled, moving overtone slider lines will always snap to the nearest tone.
Draw overtone ambitus
If the overtone ambitus is enabled, the keys on the piano and the overtone sliders will be colored according to the range of singable overtones. This feature is mostly relevant for overtone singers and composers that want to see if a given composition is singable in overtones.
Accidental
This determines if the notes on the black keys of the piano are displayed with the sharp or flat sign.
