I agree Steve. If the filter were slightly different as to center frequency
although still 2.4 KHz wide and the BFO was slightly down the slope on the
lower side then there would be more "low end" to the audio and thus a bit
warmer sound would be realized. Of course there would be a bit less high
end but in the male voice there is little worthwhile energy above 1.kHz
anyway.
