Plugin Type:



Applies a simple band pass filter to the current selection. A band pass lets a certain range of frequencies around a center frequency pass and filters out frequencies that are below or above the center frequency by more than half of the bandwidth of the filter.

The filter has grade two and is implemented as described in the book "An introduction to digital filter theory" by Julius O. Smith and in Moore's book, where the normalized version from Moore's book is used.


Center frequency of the filter in Hz, must be below half of the sample rate of the file.
