Secondary Harmonics

Subject: Secondary Harmonics
Date: Tue, 3 Jun 2003 13:08:07 EDT
Dear Experts,

I seem to remember form my class at Cornell many years ago that secondary 
harmonics as shown on a spectrogram are really a result of the recording 
equipment and filtering these out of a cut will not degrade the final audio 
Actually, what I am trying to determine is if I filter a cut to reduce insect 
noise and this noise is also in the band where the secondary harmonic is, will 
I be significantly degrading the final audio product?

Any ideas are greatly appreciated.
