Filters are defined using pass and stop frequencies, corresponding to the 95% and 5% amplitude points on the filter (see images below).

Performance warning: Band-pass filtering is a computationally-intensive process that requires processing entire traces. The resulting output volume may be slow to use. Consider:
The Band-pass Filter performs high-, low-, or band-pass filtering on a volume based on a frequency range. The process uses a zero-phase Butterworth filter that passes a range of frequencies and rejects frequencies outside the range.
