Ummm errr .... yes it does.
2 of the rooms I did had NO I repeat NO bass traps or treatment of any sorts. We fired up a track he was working on and I told him to make decisions based on what he heard with Arc on, 30 mins later and a quick trip to his front room hi fi confirmed when A/B'd that the Arc version of the dance track was a lot better than without. The Bass before was non existent because he had this huge honky 12db of flabby bass end freq. the top end was over hyped due to the reflections from the wall and having large monitors in the tiniest room I have ever seen used for a studio.
All his mixes were always midrangy bass light with dull tops and the vocals always seemed to sound wrong.
30 mins later and some very drastic changes the mix sounded a lt better just with a few level changes and a lot of eq's taken off that were on.
Of course I could be lying but then why would I having nothing to gain. I don't know much about time responses etc, but I do know when something sounds correct, and if the end result is a great sound coming from the hi-fi, Ipod or the tv then it's job done.
I mean look at the freq responce graph I posted, listen to the with and without Arc examples I posted (on headphones of course), do you really think it has no benefits at all?
Sure you could spend £300 on more bass traps, but in small rooms there really just isn't the 'room' or if like me you already have 7 large traps up and it still sounds like crap because the room is just too small for traps to fix. The proof is in the pudding, I've had just over 40 releases under my belt for Dance music so I've managed to figure out when something translates well. Wouldn't work without it.
frequency response..... but who really cares about that?
Like I said before, I would have thought that was the most important part. If I am hearing 12db boost (due to room errors),on any bass note that is a G then if my song is in G I will end up turning the bass down by -12db more than I should. If I work in the key of C where maybe a massive null (there is a huge one in the example I posted) then I would end up boosting the bass by silly amounts.
If having Arc on stops this then guess what....it works whoopy I can now trust my decisions a lot more than without.
