The AudioNetworks
"Recognition Factor"
The Recognition
Factor, first introduced by AudioNetworks in the late 80s is a way to
measure the "credibility" of a recording playback, when compared
to the live original. It ranks from Zero (totally destroyed) to 1 (undistinguishable).
The typical
experiment assembled by the first researchers to "measure"
the Recognition Factor was a human speaker talking behind a table compared
to its recording at the same position with its head replaced by a hardware
"speaker" (in most cases a combination of speakers). Each
components of the chain of equipment replacing the human speaker generated
unperfect results and were successively replaced by "improved ones".
The importance of the fluctuation produced a sort of weighting inside
the system, helping researchers to classify the most important areas
of research needed.
The resulting
list of 66 points to improve in the system was the famous "66 steps
to heaven" which dictated the Goldmund Group research program for
the last 35 years.
