I recently started doing sound mixes for tv programmes and I can’t seem to get the programme level as loud as the surrounding audio i.e continuity announcer, ads etc. My settings: if I take the narrator, I adjust the volume gain until the narrator peaks between 4 and 6 PPM (4PPM IS -18DBFS). I insert the protools audio suite vocal compressor across the dialogue buss with the following settings. ratio 2.5:1/ threshold -14 / gain 4.2 /knee 10db and attack 1.2ms. I then apply a L2007 mastering limiter across the master mix , max output -10db and threshold -11.5db. If I reduce the threshold on the limiter the sound seems to get overly squashed. The surrounding audio on the tv channel seems to have a better dynamic range with out a loss in volume. From these settings would anyone have an idea of what I might do to improve on the volume issue?
The simple answer is you won't unless you are prepared to squash the life out of your programme. The key issue here is that the PPM is not an indicator of loudness, it is designed to tell you where the peaks are which was crucial in an analog world. However the ads are processed very heavily so that my ad is louder and any other ad and the poor viewer has to dive for the remote. We are slowly moving over from normalising to peak level, which is what we do now, usually PPM 6 in the UK and across to normalising to loudness -23 in the Europe and -24 in the US. Take a look at my Loudness overview post on Pro Tools Expert
As to your workflow, I usually put a mild compressor on the dialog buss and allow up to 6dB of gain reduction, but I put a different comp on the narrator which is more severe. This helps the narrator to sit over music and also has the effect of making the narrator sound more authoritative.
Hope that helps.
