NOTE
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:
y

For linear amplitude interpolation and log frequency interpolation, the interpolation
is computed as:
-------------------------------------- - log f log f
y
=
log f
For log amplitude interpolation and linear frequency interpolation, the interpolation
is computed as:
log y
=
For log amplitude interpolation and log frequency interpolation, the interpolation is
computed as:
