If you can't hear it then see it.

This is a simple and cheap circuit to build.  By
adjusting RT1 and RT2 using switched values you can
make the circuit center on a number of center
frequencies.  Connect it to  the line level audio
output.  I built one that is discretely centered on 4
switchable freqs: 280, 350, 500 and 700 hz.  Most of
my listening is at 350.
