A Diamond Cut user recently pointed out that it is not clear how you can monitor what you are removing using the Brick Wall Filter. Here is how it is done:
------------------------------------------------------
You can monitor the signal being removed by the brick wall filter by previewing using a reciprocal filter. In other words, if you are using the Bandpass filter, switch the system to the Bandstop filter to hear what is being removed. Similarly, if you are using the Lowpass filter at a certain frequency, switch to the Highpass filter at the same frequency to hear what is being removed. The same logic applies to the Highpass filter; just use the Lowpass filter set for the same frequency to hear what is being removed.
