excellent, thanks!

builds and runs fine, will probably be using it for real before the end 
of the week. can i suggest two small extensions?

* it would be great to have the input gain displayed numerically in the 
display as well - i need to document my sessions so that i can always 
revisit them in case the client requests changes. now i could just make 
a screenshot (as i do for zita-rev1, which works because small 
deviations in setup don't have dramatic effects), but for limiting, i 
need absolute precision and 100% reproducible settings. trivial patch is 
attached.

* i'm assuming you are looking at the maximum level of all channels, and 
then apply the same amount of gain reduction to each of them. certainly 
the way to go in speaker-based mixes. but as i already mentioned over 
that coffee at ICSA, do you think it could be useful to add an ambisonic 
mode which would apply the gain reduction only to the component that's 
actually over? my hope is that the result is more subtle, because only 
the source sharpness would change slightly, and with b-format, there is 
no danger of irritating jumps of the source...


best,


jörn
