I can't actually tell you specifically what to do, because I don't have access to your audio. There's nothing to stop you normalizing the music track to -2dB in Waveform view, and then doing the final level tweaks in Multi-track. The reason for this is dead simple - no two audio jobs are ever the same! It's the same with EQ and compression - there's no absolute law says you have to use it - you make decisions based on what your ears tell you. The thing about Audition is that it does a heck of a lot of things - and the chances are that for any given job, you won't have scratched the surface of it, so I don't really know why they picked out that bit in particular either. I only asked about that because Audition hinstruction seems to make a big thing out a final submix and Master, and i didn't know if that would help or was necessary. That way, you don't have people leaping for the volume control all the time. So if you set the narrative peak to be -1dB, everything else will follow suit either beneath this, or, if there's no narrative, at no higher a level than -1dB either. In general, you need to keep the narrative at a consistent level, and alter everything else around that - altering narrative levels is pretty much a no-no. Also, if you now think that's too high for a noise floor, it's possible usually to reduce this using NR without a load of artifacts.Īnd if you aren't having to be straitjacketed by a broadcaster, leave the whole business of ITU, ATSC etc strictly alone, and use your ears you will end up with a better, more consistent result. All that happens is that it moves up uniformly by 8dB. The huge advantage of doing it this way without actual compression of the whole of the audio is that the noise floor doesn't bounce up and down, which is really distracting. You don't want to use the Input Boost, really - this tends to 'harden up' the sound somewhat. After you've done this you can normalize again up to wherever you want the max level to be - as I suggested earlier, about -1dB. So the correct process for doing this is initially to normalize your file to 0dB (because this is the reference point that the Hard Limiter uses), and then apply Hard Limiting so that the Maximum Amplitude is -9dB, Insert Boost is 0dB, the Lookahead time is 7ms and the release time is 200ms (fine for speech). Yes you can use the Hard Limiter, but I would use it without makeup gain. When you've squashed those peaks, you can just normalize up to about -1dB, and that will be fine initially. By and large, you can take 6-9dB of peaks away without anybody noticing, and that's just using a flat limit at that point - no fancy compression ratios necessary.
Generally you don't need to compress a narrative as such - if you want to make it effectively louder you limit the peaks, which means that the overall level can get closer to 0dB without overloading.
