Sound Card Calibration help

[strider445]

Apparently I'm not very good at this. I've been working all morning to calibrate the M-Audio MobilePre external sound card that I'm using, and I can't seem to get graphs that look anything like the tutorials I've read from the rew manual or youtube videos. I attached some pictures to hopefully help illustrate what I am attempting. I have had multiple problems calibrating and testing, and I am starting to suspect either the sound card is faulty in some way or that I simply have no idea what I'm doing. Thanks again for your help and patience.

The soundcard calibration require a cable connecting the line input and output (as explained in the Help Files). Not seeing that in your pictures.

Most interfaces of this type pretty much have ruler-flat response, so the calibration isn’t necessary.
