Thanks,
Ken, that's extremely thoughtful; my 'latest' 64bit ARC version was buggish ... but I got the 1st 64-bit ARC version working, IIRC (after a Window's backup-restore session).
Back on Topic:
Again, I'm glad Ethan chimed; I will always have his opinion nagging my conscience, because what he states is invariably supported by devout evidences and double-blind studies.
Hypothesis ... currently I hypothesize that compulsive attention to room accoustics and bass traps, while ideal for yester-year, do not help pro nor home artists ... to significantly create ... and/or sell records anymore ... today and tomorrow
Case studies: Some supporting cases in the here and now,
Cian sings in his sister's bedroom with just the window curtain behind his standing mic.
Reece (the Beagle) sings against a room corner, with a vaulted ceiling.
Yoyo, iirc, claims no elaborate studio ... but is my fav vocalist ... due to creative layering and mixing.
Herb (GuitarHacker) oft holds a condensor mic (angled) in his hand and sings country as well as (or better than) any *pro*, IMHO.
I myself have sung in motel rooms and in my Toyota Prius with an
SM58 and a toyish
CW UA-4FX in my 2 latest songs: Army of the Lord and Trouble in the Hood. Both of these have received favorable crits by many.
Danny... whose vocs and guitars are some of the most exquisite and beautiful on the planet (to my ears) ... masters and produces for artists around the world (they keep him busy every night, every night that he's not performing with his band in a show, iirc). His universally respected golden ears don't require bass traps. Neither did the last 4 songs we did (at any level from singing to post-production)
Conclusion and Discussion:
Based on this data: Bass traps, tall rooms, etc. simply do not significantly affect the sweet spot for listening, becoming creative, singing, mixing, and mastering today's music ... ARC is a suitable workaround for many producers, but there are other workarounds (below). Much depends on target listening areas, target audiences, etc.
ARC, compensates sufficiently for bass frequency 'early-reflections' and stereo imbalances (not just EQ) ... to allow THAT cost-effective sweet spot in the most humble of basement studios. Perhaps Danzi could produce better in his kingly studio than in his modest one ... but I prefer his modest one after all ... for my ears.
UA and Abbey Road Studios' accoustics, while quite nice, do not significantly help artists 'become successful' anymore than village schooling is more successful than homeschooling ... results are nearly the same ... with many emotive human factor variables going on.
Interestingly, mixers and MEs are forced to sit in a pretty tight sweet spot with their near-fields anyway ... but they also evaluate in mono, with multi-speakers, with headphones and listen on different stereo systems ... including car systems and radio. Translation is always tricky, IMHO.
Room accoustics, by inference, seem much more important in theaters than in studios ... where the sweet spot is much broader.
Ethan OTOH, iirc, has a treated home theater where he also tests, demos, and, perhaps, performs much of his classical instruments (being a multi-talented musician-performer himself, iirc). I'm certain his elite scenario is ideal for someone as advanced as he, who deals with a great plethora of classical instruments or perhaps records many band performers and/or singers at once (other than drummers). I wish movie theaters employed all his suggestions.
I can appreciate how his acoustic science and book will help our studios and aspiring audiophiles like myself.
