Ok. I thought that ND worked like a multiband expander (because it reshapes the attacks) and so, could be located after a wideband AGC (or leveler). And the same for auto EQ which, I think, works like a multiband AGC because it optimizes the distribution of low, mid and high frequencies and prepares the work of multiband compressors.
That's how I saw things.
If ND is after the AGC, then any level changes (if ND does a lot the level goes up) wouldn't be handled by the AGC anymore.
For Auto EQ it's more debatable, it doesn't alter the audio level (but it does change the spectrum) so as long as you don't use the AGC side chain it won't matter much. Auto EQ itself ignores audio levels, so for Auto EQ itself it doesn't really matter where it's placed. Given that, feeding the Auto EQ output into the AGC gives the AGC a more "normalized" spectrum, which will lead to better results if you are using a side chain. Which is why it's placed before the AGC.
