Transient Selection
Select a transient (a short, sudden burst of energy spread across many frequencies, such as a click or a drum hit). Click on a transient: the selection snaps to its exact time position. Drag up or down to extend the frequency range to scan. Only the frequencies where the transient stands out by more than the Threshold are selected.
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 transient.
Threshold: How much louder, in decibels, the transient must be than the content just before and after it to be selected. Higher values only keep the most prominent parts of the transient.
Sample All Layers: Use all layers to perform the transient detection, not just the active layer.
