Affects: all trace amplitude graphs
Normally, the trace amplitude reference is taken from a single point in each frame. By setting this parameter to a larger value, you can cause the program to search an area of the length you specify, from the given "Trace amplitude ref", for a maximum or minimum level. This level will be used as the reference level which is subtracted from the sample level.
