Does anyone have a schematic (or link to one) of a circuit that will
convert very low (below human audio) and very high (above human audio)
to somewhere in the 20Hz to 20kHz range? Even if there are 2
schematics (one for low and one for high) it would be helpful. Thanks.

I'm not sure. I thought it would be interesting to hear how many sub
and super sonic sounds are around us. Anything above or below normal
hearing range is good.

Google for "bat detector". Those convert bat
ultrasonics to the audio range.
