Dear All, I have a problem of calibration of my soundcard embedded in my notebook DELL D830.
I can perfectly calibrate the amplitude but not the phase response.
I am using REV 5.01 beta7 and I used a known good loop cable.
Windows 7 32bit is my OS. Soundcard OS settings are for the best performance 24bit 192 kHz max.
(By the way, I have also the problem that REW 5.01b7 has only options for 44.1 and 48 kHz sampling... is it a bug or is so limited by design?)
The problem I have seams also dependent by the samling frequency.
In order to explain the problem I am providing 3 screenshots:
1) 44.1 kHz NOT calibrated amplitude and phase response
2) 48 kHz NOT calibrated amplitude and phase response
3) 44.1 kHz Calibrated response showing anyway a big phase error near 30Hz
My opinion is that there is a bug in the REW 5 or a problem in my notebook sound card or in its anti alias filter.
Anybody know what's the problem and if it is fixable?
Thanks in advance for your support
Kind regards,
Andrea.
