It appears that Dolby Volume is going to be (it’s not out yet) only a 3-band AGC, and it appears to have basic gating (perhaps windowed/targeted) and doesn’t use digital sample peak levels for it’s control signal (probably weighted RMS, with some kind of transient-induced attack/release modifier)
But yeah, it’s still nothing new, and if you understand enough to "peer into" their marketing fluff (which is the only information available right now)… Then you can understand how Breakaway is superior in every regard, and much much more.
In my opinion nothing is going to beat Breakaway at the "game" of emulating analog-styled processing. The next processor that sounds better is going to have to leave all of that behind.
Even processors like IDT’s "DVP" platform are still half analog-emulation machines at heart, as revolutionary as the processor was at the time and still is. And it still has a hard time competing with Breakaway even for DAB, but thanks to Leif’s AWESOME FM limiting & clipping, *NOTHING* can touch Breakaway on the FM dial. Not even close.
But only time will tell. I think eventually the newer methods of audio processing, the ones that don’t emulate analog but enter into the realms of math, are going to eventually blow away the abilities of the processors we have now. But that will be at least another 10 years.
