Not exactly… it predicts what it thinks the result will be - NOT ACTUAL.
So it may or may not works as intended - ie actual measurement to validate that indeed the correction resulted in what it predicts. This is what I meant by “validation”.
I’m not sure how much “correction” is actually accurate…
In my case, I retained the same default 5kHz correction freq range and
ARC showed the predicted result as below:
ie the corrected curve (white pink line) is supposed to be I dunno, ±2dB max from the target curve (black line).
However below is the actual from REW.
It seems the peak and dips are still very much ±5dB;
Maybe they are using a higher level of smoothing…
It is always good to be able to show hard data to support subjective perception. In any case, actual perceive sound is much better with ARC “on” vs “off” which is the most impt thing
