[sdiy] active fluctuating treble boost

okay, so i have an idea for a signal processor.... tell me what you
guys think, and tell me of any major flaws or whatnot. okay, here's
the idea:
run an analog tone into a 9400 converter in F/V mode, so as to create
a fluctuating voltage at its output. this voltage is then converted to
a fluct. current and fed into an opto-isolator. then you'd have a
fluctuating resistance, which could be able to control any res. value
in any component, but my main idea for its use would be treble
boosting. that resistance would be used to change the amount of treble
boost in a basic active treble boosting circuit so that when the input
received a lower frequency, the boosting would be greater, whereas
when the input was a higher frequency, the boosting would be less
noticeable. the purpose of the circuit would be to clean up the
muddiness of lower frequency signals lacking intonation, without
increasing the treble of already crisp high frequencies, avoiding a
piercing tone.
any input is welcome.
thanks guys,
spencer
