Thanks Tom.

While I love the idea of a spirited youth developing a useful hack, there is tender turf to tread making a broadcast-stable app.

Perhaps in some low-profile town hall meeting it is appropriate, but I'm not gonna hang my corpy hat on it.
Even Mr dugan had to start somewhere. :D

"Even Mr Dugan had to start somewhere. :D"

My point exactly! Everyone starts "in the garage" (though now its "in the cloud"). And the old guard doesn't cozy up until the concept is fully developed and demonstrated.

Same as it ever was...

I am currently working on a big update. This will include the following changes:
Speaker Control will work on all 32 Channels.
IP-Range will be expanding.
The Aux-Ins will be controlled with “START” and ”Continue” as well.
               
Until it is fully tested you can use X32AutoGain with X32 Firmware 2.01 by entering the following code into the IP-window:
U2U-VfK-DRk-IAP
               
An input-box will appear.  Please enter the firmware version 2.01 .

I would appreciate any ideas about improving the program, especially Speaker-function (Automixer).

A +1 for the "Dugan" algorithm. This is public domain so free to use.

Simply put, to perform a Dugan style auto-mix you capture an average level for each channel in the auto-mix, and a average level for the entire mix sum of all (with no gain adjustment).  Then compare the individual channel levels to the sum of them all. If a channel is lower level than the sum of all, reduce it by that difference. So if it is .7x the level of the sum apply a gain of .7x, etc. It's that easy,,, This approach delivers a nominal apparent NOM (number of open mics) of 1x.

Good luck

 :)  http://en.wikipedia.org/wiki/Automixer

"In 1997, John H. Roberts of Peavey Electronics was granted a patent for an automatic mixer priority circuit, enabling a hierarchy of logic weighting that allowed selected signals to push forward in the mix when they are in use, while still maintaining the useful constant unity, gain-sharing relationship first described by Dugan. The hierarchy enabled a host, moderator or chairperson to speak over other participants and retain control of the discussion.[31] Peavey's Architectural Acoustics division used three levels of hierarchy in their 1998 "Automix 2" product, placing the first- and second-most influentially weighted sources at inputs 1 and 2, respectively.[32]"

Yes I know a little about automatic mixers...  and other stuff too...
