SPL-calibration using calibration file

[Wei Lin]

Hi,

I would like to make a calibration file of my microphone (an USB mic, not UMIK-1).

I wonder what kind of information needs to be provided in the calibration file in order to make REW treat the microphone as a SPL-calibrated one ?

I tried the calibration file of UMIK-1, but REW doesn't recognize my microphone as a SPL-calibrated one.

Thanks

REW needs to recognise the mic type (from the device name) so that it knows how to apply corrections for the input volume control setting. The effect of the input volume control on data from the mic is different for different mics so there is no general solution to accepting a USB mic.
