Many "rich" tones (like guitar, piano, ... and, often, voices) have strong harmonics -- frequencies which are multiples of the "fundamental" note.

Often, one of those "harmonics" can be louder (stronger) than the fundamental -- particularly those which are octaves (doubling of the frequency). Thus, Oldghm's example.

On the other hand, our ears sometimes hear harmonics from two lower tones which are NOT strongly present in the original electronic/acoustic signal, and thus can't be removed by trying to filter the "heard" frequency. So, it is also helpful to try tinkering with frequencies which are 1/2, 1/3, or 1/4 of the "offending" frequency.

Hi Dan,

Interesting idea (see bold below).

I would like to explore this idea - do you have any references?

Thanks.
