Hi Tom,
Be aware that a LDC as omni does not make a great test mic, as they are not very omni past 8kHz. The test mic that came with ARC is probably a better mic to use.
 
You can see a polar response of an example of the 414 family graphed here: http://www.akg.com/C414+XLS-1039.html?pid=1024

So...... did I make a good investment in ARC/ARC 2?
 
I need someone to tell me in layman's terms.

I've rigged up VAC and PedalBoard to have all of my computer audio going through ARC2. To be able to listen to Spotify in such glorious audio quality alone made it a good investment, even before the mixing benefits.

"So...... did I make a good investment in ARC/ARC 2?"
I "think" we did.
Mike brings good points to the discussion, HarBal is giving us an averaged analysis.
Perhaps a "better" test is to run Ethan Winer's sine wave test?

If I was only looking at the graphics, I'd say ARC was a placebo.  Freq responses look pretty close, before and after.  I know 31 band EQ on the monitoring chain in a studio seem to be a no no...for the supposed phase issues created, even though you see them in live setups all the time....  But, I'd think they'd almost do a *better* job, like you'd set up a PA in a new room.   People have talked about that for years and years, applying that same method in the studio.

"Is the the top line in that Har Bal window a direct return or running through a speaker?"
The top line is the wave file (analyzed by HarBal) that I used for the test.
The bottom line is the "captured" (recorded) wave file, mic in the "sweet spot", ARC was not ON when that pass was made.
"For a fair comparison, you should increase the y-axis limits on your plots to match the +/- 15 dB limits used in the ARC"
Look in the upper left hand corner of the HarBal display. Magnitude x +10db.
So I believe we are looking at 10db per line, not 1 db.
Check the link I posted, the graphics are bigger.

I made a few test tones today:
 
test-tones-2014.zip
 
There are two linear frequency sweeps from 10Hz to 20kHz. One is 0.5 seconds and the other is 5 seconds.
 
There is one 30 second pink noise file that has an exact average power of -20dBFS RMS.
 
I thought you might have some fun with the sweeps and you might find a 30 second pink noise file handy
 
 
 
 
 
I can't seem to spell while multi tasking

This is by far one of the best investement i did ...and by far the Tools pretty all myststudents get (and i have 350 per year !!) , it's just a must have with good acoustic and great monitors
 
By the way for those that still don't know , you can use it in winamp via vst adapter  to listen to all your music ;)

Yes. Arc works for me.l finally has a mix that is sounds good in my home stereo and car stereo. That speed up my work flow and confidence.

I ran Mikes test tones (thanks for that Mike!).
Below are the results:

The results look pretty similar to the Pink Noise. The "brighter" line is the ARC corrected capture.
I think I had the 10k roll off engaged on ARC, I usually mix that way the A7's are pretty "bright".
I guess we need the "pretty waterfall" software!

I often wonder why folks don't just buy an Audyssey MultEQ equipped receiver from one of the big name manufacturers and stop messing around with routing stuff through VSTs.
