This new version allows operation across all tracks in your mix session so you may ascertain the quality objectively of any processing you've made individually on any track and its affect within the context of the overall mix.

Just being able to bypass entire chains or the entire mix itself with one click turns out to be amazingly powerful.

Perception A|B is a two-part plugin with the Pre instance inserted first in the channel or mastering chain. The Post instance is placed at the end of the channel strip or chain.

In my mixing work, I'm often asked to also master it to be all ready for streaming. Perception A|B comes in handy to show to my clients what my mastering processing will do or cannot do--comparing before and after the limiter and/or stereo bus EQ.

I have been using a Pultec EQP500 Equalizer followed by a Manley NuMu Stereo Compressor followed by DMG Audio's Limitless limiter. I used the Pre instance at the beginning of this chain and the Post instance after the limiter.

I'm still getting the hang of using Perception A|B and I'm glad to have it for my mixing work. I can tell (and show my clients) who want it loud and do not necessarily hear what happens (big squashed compression and dulling) overall to the sound. Now, I have a way to make it loud more objectively with greater precision and have a way to compare realistically.

Perception A|B sells for $149 MSRP and runs on AAX, AU, or VST systems on Mac OS 10.7 or later and Win XP SP3 or later 32/64-bit.
