Re: Sound Card Calibration Help


Yeah, looks like you have it working good now.

How would I isolate sound to the Center?
The receiver should only be used in stereo (or mono) mode. Never use a sound field.
Isolating an REW sweep to a center channel is accomplished by removing a main speaker wire and substituting the center channel speaker wire and turn the balance over to that channel.

Also note that if you're using a Radio Shack meter, the full range measurements aren't accurate above ~ 3KHZ at best. See that peak at 7K - likely the meter causing it. Limit the sweeps to 3KHz. If you want to do accurate full range measurements, you need a better microphone and preamp such as the ECM8000 and XENYX802.

Another note: start all your horizontal axis' on your graphs at 15Hz (and not 2Hz)..
