[Shane Ross] “broadcast peak levels are -12db.”
“Peak levels” being the operative term…
What I was previously referring to is the bars&tone VU level of 0=-20… just to dot the i.
You are, of course free to record at any dynamic level you want — in the field. I often get music tracks that are “full range”, which of course, have to be cranked way down to get under the -12 peak threshold. Be aware that the FCC is levying fines now under volumetric uniformity laws. All that complaining about the commercials blaring away and destroying the mood eventually held sway, I guess.
Be careful about recording too low and cranking the SPL up, though. As with all things sampled/digital, you run the risk of amplifying quantizing noise, the same way we get banding in 8-bit video.
The other gotcha is that as overall levels get cranked up and down, the overall relative mix between dialogue, music and effects will change perspective, and what, at high levels, sounds evenly distributed, will get crowded with some elements starting to overwhelm or get buried by others. Thats the beauty and mystery of sound mixing.
