Post Calibration (Logic & PT)
Hi - I've been doing lots of post lately, so I tried calibrating my speakers. I set everything in Logic to Unity, turned on some Pink Noise @ -20 dB, then cranked my interface until my SPL meter hit 79dB (small room). (Slow response, dBC)
However, when I move to iTunes, QT, etc. the output is "blow up my speakers" loud. I have to set iTunes internal volume to almost zero.
Is this normal? Should I just change my interface output when I go back and forth?
Also, I did the same calibration test in ProTools and got a very different output. (3 or 4 dB) I've read threads on Pro Tools and Logic having different output levels, but people keep denying it. I tried all the Pan Law options, and still the discrepancy. Even playing back a test tone sine wave file in Logic and PT gets different output levels.
