Remarks: If two amplitude values are entered for the same frequency, a 
single vertical line is the result. In this case, if an upper line is 
chosen, the amplitude of lesser frequency (amplitude 1) is tested. If 
a lower line is chosen, the amplitude of greater frequency 
(amplitude 2) is tested.
For linear amplitude interpolation and linear frequency 
interpolation, the interpolation is computed as:
For linear amplitude interpolation and log frequency interpolation, 
the interpolation is computed as:
For log amplitude interpolation and linear frequency interpolation, 
the interpolation is computed as:
For log amplitude interpolation and linear frequency interpolation, 
the interpolation is computed as:
