Hello,
I'm trying to calibrate my simple stereo speaker setup so I can use this setup with Pro Tools for small post-production audio jobs.
I have a smaller room so I want to calibrate the speakers to 78 dB.
I received my miniDSP UMIK-1 mic from Cross Spectrum, which currently I want to use as a SPL meter via REW.
I have a few questions:
(1) I got the sensitivity data from the miniDSP website and I pasted the data into the cal files from Cross Spectrum. Am I correct in assuming the sensitivity data needs to be on the first line in the cross spectrum cal files to be used within REW correctly ? Or does it not matter where in the file it is pasted ?
(2) Where should I point the mic to when taking a SPL reading ? directly at the speaker that is being measured or should I point the mic straight ahead in-between both speakers, basically having the speakers at 45 degrees to the mic ? I keep reading different statements about this...
(3) Am I correct in assuming that using the 0 degree cal file from Cross Spectrum should only be used when pointing the mic directly at the speaker ? If pointing the mic straight ahead in-between both speakers, should I use the 45 degree cal file ?
(4) when using the mic as a SPL meter using the REW SPL tool, will it function like a standalone SPL meter when using the C weighting function ? Or do we need to use the Z weighting as this is a mic that emulates a SPL meter ? I saw tutorials where Z weighting was used for SPL measuring when using a mic, but the general tutorial for speaker calibration with a real SPL meter uses C weighting...
I just wanna make sure that there are no "special rules" when using a calibrated mic with sensitivity data as a SPL meter inside REW...
Thanks.
