Select a continous serie of harmonics (multiplie frequencies on top of each others) by automatically tracking how it changes over time. Click and drag over a frequency to start selecting, then move to an harmonic below or above the selected frequency to select all harmonics at once.

Replace Selection: Replace the current selection with a new selection.
Add to Selection: Add the new selection to the current selection (or press Shift).
Subtract from Selection: Subtract the new selection from the current selection (or press Alt).
Intersect with Selection: Intersect the new selection with the current selection (or press Shift+Alt). This will keep the common areas between the two selections.

Thickness: Defines the thickness of the selection around the frequencies.

Tolerance: Max power drop in decibel (compared to the hovered frequency) to still be considered part of the harmonic sound.

Max Harmonics: Max number of harmonics to be selected, starting from the fundamental.

Sample All Layers: Use all layers to perform the harmonics serie detection, not just the active layer.
