With an SPL meter and the ability to run your laptop, desktop, etc. through your main rig you can learn a lot about your rig and your room. This is a great tool to get an idea of room response, speaker response, sound stage and image capability of your particular set up, proper phase....lots of good stuff here to remove a good chunk of guesswork wrt dialing in your rig and troubleshooting.

I bookmarked it too...
after TRYING to burn some files.
TRYING as in I'm too computer illiterate to succeed in burning the files.
But I did use my new SPL meter and new Stereophile test cd 2 yesterday to run some tests.
Was surprised/saddened to discover I can't hear much above 12.5kHz.
 
If you have a SPL meter to go along with the computer used to access the internet, just download a copy of REW from www.hometheatershack.com . Not only does it do just about everything you could want vis a vis testing, calibrating and adjusting your system, it has a very helpful forum and knowledgeable user bass to provide help.

REW, though far superior in terms of a measurement tool, is an order of magnitude more complicated to get up and going and to use. Figure on several hours for those tasks alone. Audio check is extremely simple to use and requires no sound card calibration, mic calibration, or time consuming research wrt how to use each feature. Now, if you have the time and equipment REW is practically unmatched in terms of free measurement software and I'm certainly not suggesting audiocheck.net as a replacement. However, it is a very quick and easy way to run tone sweeps and bursts to listen for uneven bandwidth reproduction as well as other basic audio performance measurements. For those who want something quick to get a good idea what's going on with their system audiocheck.net is the best I've come across.
 
Cool! What SPL meters do you recommend for a starter?

12.5 khz ain't bad. I'm the same now, losing it just above 13 khz. I saw someone complain about not hearing much above 17 khz, and doubted it was that high. Not a lot going on above 12.5 khz anyway, and you're likely hearing 99% of the music that is there. More troublesome to us as we age, imo, are those 'notches' we tend to get in the mids - you know, those frequencies which correlate to your wife's voice.
 
I calibrated for a hearing test and results weren't surprising given
hearing loss from 15 years in manufacturing and 25 years in the welding trade.
At 125, 250 and 500 kHz, I rated between 20 to 30 dBHL.
At 1, 2, 4 & 8 kHz, I rated between 40-60 dBHL.:yuck:
Thanks to the OP for the link.:tresbon:

Too bad I'm restricted to the garage/man cave. Can't make this place "audiophile" friendly, no matter what I do :(
 
Keep in mind, guys, the hearing test feature of audiocheck is certainly cool but explore a little and you'll find some very cool test tones you can run through your speakers that will tell you all kinds of stuff about what your system is, and isn't, doing.

Oh, come on now. It's a blessing in disguise.....you can do what you want out there.

I never thought of it that way. You are correct though. There is a steep learning curve associated with REW. It was a week or more before I felt reasonably comfortable using it. I guess being retired and having lots of spare time influences my thinking.

I want to add, for those that think having diminished hearing acuity somehow makes using one of these tools superfluous or unnecessary, think again. Anything that can help make your system less room dependent is a plus. You don't need hearing to 20KHz to hear the difference one of these applications can make.
