[Elecraft] Vocal Cord Bias + SSB PEP

[Nicklas Johnson]

An audio engineering friend noticed in some voiceover recordings something
that I've also noticed in my own waveforms, that a lot of the time, human
vocal cords seem to produce a biased waveform (seemingly a positive bias
most of the time).

I vaguely remember reading either here on this list, or maybe in QST,
something about this as it relates to setting microphone gain (and bias) so
that the resulting modulated signal is making more efficient (I'm probably
not remembering the right word) use of the available amplitude (ie, not
hitting the peak early on the positive side, but falling well below it on
the negative side).
My Google-foo isn't working out for me today though; does anyone remember
an article or posting on this topic and/or have a link to it?  I haven't
been able to track it down again.
