Hello everyone first time poster long time lurker.
I have finally gotten around to calibrating my subs and have been trying to learn how to use REW the past few hours. I finally was able to calibrate the mobilepre sound card and resulted with a proper looking graph. When I attempt to load the file I get an error message saying:

File parsing error at line 3. Line has frequency -3.00 which s not higher than the preceding frequency -0.00.

Has anyone seen this error message before? I have no idea what to do at this point. If anyone can assist me I would be very appreciative.

Thanks
Forin

mdat files are binary measurement filess, cal files are text files with frequency, gain and phase on each line. Maybe you did not click the "Make cal..." button at the end of the soundcard calibration process? That generates the required text file and automatically loads it.

Great, thanks for the advice John I was able to get it to work. Soon as I get some free time I will attempt to grab a FR of my subs. Thanks!
