I generally work in film. I have a broadcast gig in which I am cleaning dialog and mixing a 23 minute spot which is going to air shortly and I do not have a Technical Specification Sheet. I am so sorry to ask these questions again (i know versions of this question have been asked), but I just need clarification and I have additional questions...
Is it correct to calibrate system to 79 dB-spl (at -20) for TV broadcast? More Importantly - Are commercials and shows mixed differently, or at different calibrations? (I understand each station may have different specs making this a difficult question).
Is it correct that I mix, Peak at -10db, and -20db for unity gain?
79 db sounds seemingly quiet. Do TV stations generally take these mixes and compress and squash them to be louder before airing? Or do I need to do an extra step after mixing?
THANK YOU THANK YOU THANK YOU!!
