Stereo Tool

O.9 Undo is kinda same concept as Declipper and ND in ST.
To me that undo knows to sound "fake", (not declipper part - that is same) ND in ST is kinda better in that aspect, but ND has huge problem, it does not have WB dynamic detection and you cannot properly 'push it'.

1.) Adding AGGRESSIVE UNPROCESSING like the Omnia.9 has would eliminate some of the audible mastering differences between then and now, such as the increased amount of compression used on music now vs. then, and would allow for more consistent dynamics between older and newer music.

2. CREATING A C-LEVEL LIKE AGC I feel would very nicely compliment the addition of AGGRESSIVE UNPROCESSING if that is added. And would be magical in combination with the new compressor, just based off of the things I’ve been told. A regular AGC tends to be way too noticeable, (I’ve heard many engineers here in the US complain about this, myself included) which, if you want the most dynamics in your audio, is not a very good thing. Creating a C-Level like AGC would allow music to stay consistent without being heard.

I think this would all go very nicely with the new compressor design!

Adding here that I've noticed Orbans have an interesting FM Lowpass filter style that allows more audio in the highs without running into the pilot or the RDS. I don't know how it would be done, but this could be something to look into as well. Could make Stereo Tool even more powerful.

I don't see how this thing that orban does, helps audio much. In fact it might create problems on some receivers due to the noise around pilot. HVZ should be able to give us an answer.

Ps i've seen this behavior locally with 2 radio stations using orbans. If you check the spectrum of the demod audio you will see that it doesn't get loud audio over 16khz. You can do much better with ST by setting your lowpass filter to more than 16khz which you should know that it might affect your RDS.

If you ask me i would prefer omnia's (telos) approach, they slightly widen the spectrum as it gets closer to the filter's limits and it looks much nicer. Stereo tool is kinda cutting the spectrum heavily but this might be also better for the vast majority of receivers.

Again i would love HVZ to give us a good "food for thought" on this one.
