I noticed that it lightens the bass in my system/room considerably. So... in the process of tracking and mixing I simply go for the sound that I want to hear. In the mix down stages, I do what I need to do with EQ and compression and other plugs to get the sound I am hearing to be what I expect it to sound like. When I finish, having added the plugs and Ozoned it to perfection (according to me) I turn ARC off and have a listen and it's like a butterfly emerging from it's cocoon and 99% of the time there is nothing that needs to be done to the mix at this point except to export it to a wave.
Indeed, ARC seems to me to essentially be a bass-trap ... in small rooms that have no bass-traps.
But SCorey seems to imply ARC is over-rated. It works well for Danny ... and I've trusted more tracks and masters to Danny with my nearly 'golden ears' gleefully validating dozens of excellent tracks and masters that Danny has performed-produced.
Just how did Philip validate so many ARC tracks and masters? Why, by playing them on multiple systems and multiple environments of course! ARC translates our monitors well for maybe 60% of real-life listens. (not 99%).
So, I think I agree with Scorey's (pre-)cautions ... but for other reasons.
I'm pondering that ARC probably fails for the following translations: Theater, auditorium, church, dance-skate halls, and perhaps the great outdoors ... where bass frequencies extend more without conflicting reflections.
I'm pretty certain the DJ has difficulties adjusting the subs (while I'm roller-skating) as many pro (hip-hop) songs are poorly mixed - mastered (to my ears).
ARC does not help widen dynamics either ... and bass-trapping may still be 'hit-or-miss' for translating the subs.
Dozens of my mixes (all done with ARC), while sounding 'pristine-perfect' at the studio, home, cans, and in the car ... sound 'saturated' excessively in large areas, church, etc. ...
Here's why:
The 'ARC sweet spot' doesn't even seem to exist in large listening areas. Stereo behaves 'differently' (detrimentally I'm observing) in large areas. In large areas, my simple mixes seem to win over my busy ones.
