Marc Wielage Posted March 15 Report Share Posted March 15 I was having a discussion with (what I suspect is) a young filmmaker on a different forum. and he's asking for a way to crank the post sound levels up more than 30dB, 30dB being the current limitation of Fairlight. I asked, "why would you need to adjust post sound levels up +30dB? That sounds incredibly extreme!" I come from old-school Pro Tools where we were limited to I think either 10dB or 12dB without adding an extra Trim plug-in for additional range. Even 10dB for normal dialogue is exceptionally rare (to me). I did some quick math and came up to the conclusion that 30dB works out to 1000 times the intensity of a 0dB signal, (subjectively) 8 times as loud... which is a lot. He responded that they had recorded all their dialogue in 32-bit, which would protect dynamic peaks and prevent clipping during the original recording. I responded that I felt that there's a point where self-noise in the microphone and in the preamp will be so overwhelmed by a 30dB boost, you're not going be able to take advantage of that range at all, and he got very defensive. What nobody wants to come out and say is: my guess is they're trying to record sound without a location sound mixer on set to just adjust levels on the fly... as has been done for at least 80-90 years. My suspicion is they're operating on the belief that they can save money and just "fix it all in post," not cognizant that the sound mixer has to get things right on set, and they'll wind up spending way, way, way too much time tweaking the sound in post, wasting the additional time and money you thought you saved in post. And I think the noise floor will still be something they'll have to deal with. What's the opinion here? Am I crazy that 32-bit recording is kind of a waste for regular (non-sound effects / non-music) location dialogue? To me, 24-bit digital dialogue has already got 144dB of dynamic range, and that's way, way, way more than can be reproduced in a theater. But maybe I'm thinking too conventionally, and maybe I'm too old-school. Quote Link to comment Share on other sites More sharing options...
