Old news, but just showing my age....*creak* ;)
Was doing all this analog back in the ’80s’ with an Audio Control C-101 (series one, since that’s what appears to be what I ran...). Yes, ’room treatments’ would and could affect what one dealt with, but the whole sounded so much better after an afternoons’ worth of tweaking....
The modern digital versions and units ’spoil’ you....makes it just too easy.... *L*
Now I can take multiple readings from various locations and ’average’ them with a poke or three...tweak from there. And have some afternoon left over...
Most annoying thing about the 101 was the calibrated mic included. About the size of the average thumb, hard to make ’stay put’ in a mike stand....but had a long cord attached....
The ’pink noise’ had a ’burbuling’ quality that reminded me of a pot of roiling boiling water on the stove, but didn’t change the overall readings. The all LED display may not have given one the most finite take on the space, but would get you as close to ’flat’ without a major (for the era) expense for a ’pro’ unit.
