Detection and the Dynamics Duo
combined power of the left and right signals.The more dissimilar the left and right signals
are, the more error in the detector’s calculated level. It’s as if someone’s continuously
messing with the threshold knob! A much better method, although still deficient, is to link
log average detectors. This results in the sum of the average signal amplitudes, but, as we
have stated before, does not correspond with average power and therefore does not sound
as good.
6.True RMS Power Summing
The dbx way, of course, is different. With our True RMS Power Summing, the linked
detectors respond to the sum of the energy (power) of each channel’s RMS signal. The
intelligence of these RMS detectors allows the signals to be converted to the power domain,
then summed together in the power domain.This produces a true sum of the energies.The
more total energy, the higher the detectors calculate the combined signal to be.This is how
your ears work--the more screaming children in one room (i.e., the more total energy), the
more irritated you get!
This sum of energies will gain track accurately over a wide dynamic range providing
excellent response at low or high signal levels. No phase cancellation, no inaccurate
modeling of human hearing response, and heaven forbid, no ignoring one channel of signal
information.When detectors are linked intelligently and sum signals the same way that your
ears do, compression, limiting, or expansion will sound the way it should!
7. Conclusion
No need for a conclusion here. You make your own. Thousands upon thousands of
industry professionals have already made theirs, making dbx the most respected and most
used dynamics processing line on the planet.
