Appreciate the reply. Which soundcard calibration file should I use in this case? If I do RTA measurements, should I use the accurate soundcard calibration even if my measurements are taken when the laptop is unplugged (unplugged gives the weird calibration)? Or use the inaccurate calibration to coincide with the laptop being unplugged while taking RTA measurements?
In other words, is it ever recommended to use the soundcard calibration with the odd reading? Or just use the calibration that has the better calibration result regardless of whether I take RTA measurements with the laptop plugged in or not?
If I use the odd sound calibration file, does that mean I will have inaccurate RTA measurements?
Thanks for the help!
