Audyssey MultEQ XT post-verification for beginner: What, Where and How?

post #1 of 8
Thread Starter 
Once I am done calibrating the speakers to the room dimensions via Audyssey, I intend to verify that the speakers are correctly leveled from Audyssey's calibration.

In order to do this I need some equipment.

Basically, I want to know, what they are, where to obtain them and how to properly use them for the Audyssey MultEQ XT post-verification task.

I have no experience in recording with microphones.

List of what I need, feel free to add missing components.
Art USB Dual Pre
Dayton Audio EMM-6
Calibration File
REW
XLR male to XLR female mic cable
Noise test files

1. If I'm recording with the mic, do I need to affix it to something or can I manually hold it?

2. Where should the mic be? at the listening position? in front of the speaker/sub?

3. What brand and model XLR male to XLR female mic cable should I get?

4. Where can I download the noise test files? i.e., a website that hosts audio files that test for frequencies that I need to record for proper verification

5. I am looking for a tutorial (preferably step-by-step) on how to set up, configure and use the Art USB Dual Pre + Dayton Audio EMM-6 mic + REW software for proper use of identifying any possible mismatched levels of the speakers and subwoofer, despite any of Audyssey MultEQ XT's benefits I would have gained. Since I can not find the main AVS REW thread, can someone link me to the thread so I can ask someone for interactive advice who uses the Art USB Dual Pre + Dayton Audio EMM-6 mic + REW software?

Please number your answer(s) to the corresponding question. For instance, your answer for number 2 should be "2. the mic should be at this location."

Thanks.

1. You need a mic holder+stand.

2. At the listening position

4. You can get the test tone files from http://www.realtraps.com/test-cd.htm but with the freeware REW (download from hometheatershack), doing frequency sweep and recording to PC is so much easier.

Thanks for the REW link.

I'm glad to know that I will be able to verify post Audyssey calibration settings with the data gathered from REW's frequency sweep.

If you use REW there's no need for separate test tone files. This will help further:

I would use the optical toslink digital output of my PC's sound card to output the frequency sweep to my receiver's optical toslink input then on to speakers?

However your system is normally connected is what you should use when running REW.

Would it be a problem if my computer (& case fans) are on while recording REW's frequency sweeps with the mic?

Probably not, but it depends how loud they are.
