soundcard calibration graph

Here's the screenshot. I have two stereo plugs plugged into the soundcard. I have an RCA cable plugged into both red females and the whites are empty.

I ran it again and got a better response this time.

Change the sweep level to -18db FS. Then calibrate your sub to 75dB.

So the soundcard calibration is good then?

Still looks like there's some interference or distortion there. The midrange dip is strange. If this is a lap-top try turning your wifi off and make sure you are running off of the battery pack and not the wall. Also check your levels to insure that something is not overloaded. May possibly be the sampling rate used? I had a problem like this when I first started, but I can't remember exactly how I corrected it

This is just a loopback measurement of the SC right?

Yes, just a loopback measurement of the SC. It is a desktop. It could be a soundcard. I could use another computer if I need to or buy a new SC. What is a good inexpensive SC to buy?

No. (note that the best sweep level for soundcard cal is usually ~-6dBFS)

Why haven't you selected the soundcard in the Input / Output selection pulldowns? (example below)

I thought it said to use the default device.
Check this graph out then.



I think we have a weiner.

Here is the subwoofer range from the same graph as above.
