I hope this is the right place to ask this question...
I have gone over the instructions several times, and calibrated the sound card several times. The results of the sound card calibration look like they should, to me at least.
Last night I tried a few room measurements, and the results can not be correct....no way...
I am using a Dell XPS laptop, a Behringer UCA202, and an Extech 407730 SPL
Here are the calibration and test graphs...
SPL and PHASE
Blue line (flat) C Weighted SPL Meter unchecked
Purple C Weighted SPL Meter checked
Room measurements always look the same, even when moving the SPL and pointing it in a different direction.
There is no way this is correct.
What am I doing wrong?
