This is a very old thread, but I just saw it. I am the technical manager of London Short Film Festival, and the author of the "how to make a DCP" guide the OP referred to. First off, I'm really sorry to hear that the film did not screen as intended. And why indeed did the DCP-making guide I wrote suggest adjusting peak audio levels to -10dB in DCP-o-matic?...

Is this requirement as ridiculous as it seems to be to me? Yes. No serious theater mix delivery specifications includes such limit. Nearly all theater mix will have sample peaks above -10 dB FS. Secondly, is this kind of level change actually normal in DCP creation? No. The mix should be delivered in conformance with whatever specifications apply. The ...

I spent a bit of time working as a projectionist about five years ago, playing standard DCPs from a Doremi server. All the prints came with a single audio format sent specifically from the distributor for the particular screen. The server outputs discreet channels and these are routed to the speakers. At the cinema I worked at we had a custom switch to do ...

To my ears, it does indeed sound as if there is too much build-up in the lower mids. I wouldn't say "muddy", but rather more boomy, boxy, or honky - those are three words I would use to describe it. Cutting these will clean it up for you, but as you said, this was definitely miked too close. Two more things to keep in mind for dlog editing: 1) You will ...

I would guess TV shows are often "mastered" either the same way or very similarly for broadcast versus DVD and Blu-Ray since the final output equipment is the same in either case. The release of two episodes of Game of Thrones was specifically described as "remastered" for IMAX, so we can expect the audio portion was mastered differently for delivery to IMAX....

My understanding is that the cinemas do not get to decide. They need to play whatever audio was mastered onto the DCP. That decision was made by whoever produced the DCP. It was not quite the same with 35mm. At first, there was only an optical stereo track on the 35mm print. Then 70mm came along with 6-channel magnetic tracks, so Dolby, Sony and DTS came up ...

Well what Joseph Santoyo said is pretty right, i mean it can get you in the ballpark and have a decent sounding vocal recording, but in no way a serious one. If you take 2 voices make a big Q around 250-500 in your situation you will be a lot less muddy but what i have seen is that when i EQ stuff that were recorded in the same room (and the room/mic/...

Exactly 2 seconds before the first frame of picture you put 1 frame of 1khz tone. Used to sync audio and video. You can use a signal generator to do this such as the one in Pro Tools.

support for new immersive sound formats like Auro3D (11.1 -15.1) and Atmos 7.1 and 9.1 ('Objects' will be stored in an additional auxillary part of the DCP).
