at least i do not feel alone knowing that the AGC makes or breaks ST, its the most important tool with ST, if its not configured correctly, everything else in the audio chain will suffer.
Maybe the AGC is working fine when configured correctly, i don't know. My knowledge of soundprocessing is not that good. I do know what sound i like, and no matter how i set the AGC in ST, i just can't get that consistent, open and dynamic sound. It just feels (to my ears) that the AGC is compressing to much where it should act like an leveller. And the sound comes out a bit flat, or dull. i don't know the word for it exactly.
With my Compellor, it's easy. ST reacts very nice to this and is much easier to configure. Only thing i do miss a bit, is the stereo matrix in the AGC, cause i really liked that.
i prefer to use the legacy AGC rather than the "current" AGC, it behaves better in the manner you are talking about.
matrix is available in both legacy and current AGC but channel separation is lost when using it (naturally).
i prefer the waveforms AGC output to be the same as the waveforms of the input when it comes to AGC control, except for applying "power bass" and "power highs" which "boosts" some low/high audio freqs that are low in level, but it does not attempt to boost low/high audio freqs that is non-existent in the audio (prevents rumbling/hiss as a result) as well as not "boosting" those lows/high levels if they are at or above the specified dB level (power bass/highs behave as a separate AGC within the AGC), this is great for older content which may have weak lows/highs.
the AGC should behave as a gain controller and not as a processor, everything after the AGC is where the processing should take place.
i am better able to configure the legacy AGC to behave in a better manner where the input and output waveforms are the same, the dynamics, peaks and valleys are much better controlled and reflected on the input/output waveforms when observed.
the key to configuring the AGC properly is to use only the AGC first, configure it to your liking, then apply all of your additional processing.
though the "current" AGC is improving, i am still not yet able to configure it to behave in the same manner as the "legacy" AGC.
one significant improvement with the "current" AGC is the "sudden jump protection", it does a much better job now at "clamping" then it did previously where the effect seemed minimal at best.
