Lower window limit

The controls shown above are used to set the lower window limit.

The  button will use an algorithm to detect the start of the time data. Currently it only works for impulse responses, and should be set to 0 for other signals.

The edit window  shows the current value in the unit displayed in  (milliseconds) as will be explained below. It is possible to type a new value, but remember to validate it by pressing Enter.

The controls  will move the window one sample in each direction and is thus to be used only if very small changes are required.
