Avatar's sound track
I started watching the "collector's" cut of "Avatar" last night, after
having watched the terrific Blu-ray of "King Kong". (The films are thematically similar.) The dialog sounded rather distant and lacking in presence. Raising the overall level a few dB fixed this, without causing the music and effects to be unduly loud. (I do not use a Dialog speaker, and I don't generally have this "problem" with other films.) Would anyone care to comment on this? -- "We already know the answers -- we just haven't asked the right questions." -- Edwin Land |

Would anyone care to comment on this? 1) deploy a center-speaker, say something KEF Coax. 2) after setup eq it + 2dB, q1.4 at 2.5 kHz Kind regards Peter Larsen |

Because that eq is what I deployed on a yamaha + klipsch setup a couple of years ago that had the same problem and an owner with known hearing damage partly from working in the coal mines down under as a youngster and partly from a diving mishap. The psychoacoustics of it is that it is a treshold of audibility vs. masking issue, quite possibly caused by the movie soundtrack being mixed somewhat louder than you prefeer to listen. Also putting the vox in a center loudspeaker as planned in the mix will reduce the temporal smear of your room, that too leads to consonant loss just as does the masking from the music and effects tracks. That explanation may be more helpful to you than an exemplification of it, but there are other people out there who read what we type here on all those "forums" that are just a clandestine and illicit echo of usenet.

Well, if you are listening to a modern 5.1 track, all of the dialogue is in the center channel, and you won't hear any of it at all, just a little reverb. It's possible to play 5.1 back on a two-speaker system by "folding" the center and surround tracks into the left and right, and your playback device may have a bunch of settings for doing this in various ways. The settings (at least on the theatre systems) that work best vary substantially from film to film. If you instead of listening to the 5.1 track listen to the supplied stereo or matrix surround track, you might be okay... but these days those tracks are definitely an afterthought and they are frequently just folded back from the 5.1 tracks. That said, I ran the film in 35mm with old-style optical sound, just two tracks which had probably been downmixed from the 5.1. I recall having to increase the center channel a little bit over nominal, but I have to do that with a lot of films these days, especially when showing in halls with a long reverb time; it does seem like so many films today are mixed to sound good in the living room rather than a theatre. --scott -- "C'est un Nagra.

I think the point that's not getting across is that "Avatar" is the /exception/. Virtually every other DVD or BD sounds fine. It's "Avatar" that seems to have weak and poor focused dialog -- until you turn up the volume a bit. I'm trying to find out if there is any psychoacoustic understanding of this effect -- or I'm just full of hot air. (No wisecracks, please.) |

Channel delay is assumed correct, note however that back when I did bother to listen to dolby surround that too was an adjustment that needed frequent tweakeing. please Try deploying a center loudspeaker, there may be other detail waiting in the mix for you to discover. Also William, you are not young, but it would be wise even if you we get the hearing threshold checked. Kind regards Peter Larsen |

Also William, you are not young, but it would be wise even if you we get the hearing threshold checked. HF-wise, my hearing cuts out about 10kHz to 12kHz. Threshold-wise, I can turn down my bedroom TV's volume to practically nothing (at night) and still understand the dialog. I do have trouble with dialog /in movies/, even when it's played fairly loud. My first experience with this was 30+ years ago, in "Superman": "Don't worry, miss. I've got you." "Mmmff mmmff MMMFF? Mmmff mmmff MMMFF!" It took me a long time to figure out what Lois was saying. I will not be deploying a Dialog speaker. I live by myself, and don't feel I need it. Besides, it would probably screw up the imaging, as my speakers are all planar. |

No, the system is configured for no Dialog speaker -- center front is split through left and right front. Right, but what ratios is it splitting it to? You're always going to have somewhat lower intelligibility when you do this, compared with using a center channel. But the ratio at which you want to set the level depends on the mix itself, because you are basically downmixing everything to a different presentation format. Once the center channel is not physically separate in space, you lose some ability to pick it out, so the appropriate relative dialogue levels are not exactly the same. And, the more cluttered the mix is, the more you will need to punch the dialogue channel up. Your dts decoder should have a bunch of menus that let you adjust downmix parameters. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |

Presumeably so with a sweep, but hearing is not that simple due to the overlap of the critical bands, signal in a lower band will partially count as a detection bias in a higher band helping sound get over even a raised threshold of hearing. There is no such thing as a frequency response for the sense of hearing, it simply is not a valid concept due to the wide variability of the hearing threshold. Increased problems with masking is the first subjectively noticed symptom of a threshold shift due to impulse noise damage, usually centered around the 6 kHz area and not very well detected initially by a "spot check treshold determination" at 2, 4 and 8 kHz. Such treshold shifts are usually not at all noticed until they exceed 40 dB. Kind regards Peter Larsen |

And I think that if you do this, you'll find that the others with the same problem are also very dense mixes. Try _Saving Private Ryan_ which I recall also having fairly buried dialogue in some scenes. No, not all mixes are like that, they are all different.

Why do the voices sound distant and poorly imaged at what is (for me) a reasonable listening level, but suddenly come into focus when I play the sound a few dB higher? Is this the way the human hearing mechanism works? Yes, and I am not sure anyone really knows how the phenomenon really works. Sometimes you can also just do a little presence boost on the dialogue and have it pop out too. You should really experiment with a center channel speaker... even just a random mismatched one for the purposes of testing. You'll be surprised at how much more focussed it makes the dialogue. I don't know why, but it was a Bell Labs discovery back in the thirties. You wouldn't think it would make any difference at all when you're on-axis, but you're never precisely on-axis. the one answer that made sense (even though it was tautological) was the suggestion that the voices were mixed at a "normal" level, rather than being raised to compete with the loud sound effects. In other words, the "Avatar" soundtrack has a dynamic range that more-closely matches the real world, rather than being squashed. This is true, and this is part of the overall denseness. Again, try Saving Private Ryan which is the film that first made popular that sort of mixing style. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |

It's amazing that, no matter how many times I repeat it, no one pays attention to what I actually said (above). I feel your pain. I'll toss in my $0.02... - in a really good room (one that's well treated and perhaps even a real mix room), I don't see why one must have a center channel for casual film playback -- unless you are doing film mixing. (In the mix room here, I've had a few of the "general public" who know nothing about audio production but who might have a 5.1 home system, demand that I reveal the center speaker. Heh. Sorry, there isn't one. "But I swear, that singer is coming out right there, rock solid in the middle! How do you do that??" What's taking place is excellent control of early reflections, proper diffusion, along with optimal RT30 performance across the audio band (and it varies as you go low to high). It all makes for good imaging, something usually not found at home, nor in most theaters. Hence the need for a center speaker -- but it shouldn't be mandatory, methinks, if you're home alone, in the "sweet spot" for your room.) - Many of the more subtle aspects of "mix art" seem to have been lost with some mix engineers -- be it film or music. Might be nothing more than the mixers doing spot checks on other sets of monitors at different levels, coming back with fresh ears a week or a month later to make *sure* everything sits where it should, etc. - mix engineers need to keep in mind that the *entire* signal chain, from microphone to speaker, is unnatural and limited. Often the mixer needs to do a little counter-intuitive magic to distract the listener from those short-comings. In music mixing, I'll often add several little gain moves (typically 0.5 to 1.2 dB) to add clarity to, say, a vocal or bass (way better than stomping the hell out of it with a comp, as even at equal levels that might not be what's required; you might need to goose the end of a phrase just a bit, for example, because the singer pulled back off mic, ran out of air a bit, or you're competing with instruments or, in the case of film, fx or music.) But the knowledge to do that takes experience and post time (budget) that might not be available. - if they're adding reverb, or had some subtle room sound floating along with the dialog, this can dent intelligibility. (Yeah, it might have been a big-time ADR room but maybe they were careless and the voices were off mic, the pattern was wrong, any number of things can slip by in the heat of the moment. And, some faults might be subtle enough such that they're not noticed until the very end of the chain -- your house.) Had they caught something like this in time, either dip the low mids a bit, or bump the mid highs a bit, or if a 'verb issue, increase the predelay or change 'verb time and EQ settings -- but they might never know if they (a) don't try the mix on other monitors and (b) don't try a check at lower levels. Welcome to the modern world where a lot of well-paid audio engineers might have never heard ANYTHING, voice or music, that didn't have transducers and electronics somewhere in the path to their ears. IMO, being a good mixer, regardless of genre or working theater (no pun), means on a regular basis hearing things in a completely acoustic setting so that you're reminded what things actually sound like -- and from that gaining awareness of all those shortcomings in our systems. Pays yers money and takes yers chances; it's nice at least that some place you can adjust the level. Frank Mobile Audio -- |

If I could get my stupid Sony to stop jumping to random audio playback
modes every time you sneeze at the remote I'd be happy. Fortunately now that we know our personal audio head scratcher is always due to the setting jumping we just set it back. But I still get occasional holler from the youngest one that the dialog suddenly dropped again, and thanks to the bizarrely configured interface it's pretty easy to make it worse on the way to fixing it, so she doesn't have my blessing to got rooting into the menu just yet. That there are so many ways to handle the audio makes sense, but jeez, the hardware UI sure doesn't make it easy. |

(in article ): Why does everything spelled out in excruciating detail? I wanted to say "comment on the psychoacoustics and/or mixing practices of this", but figured it would be obvious. I guess not. Because that eq is what I deployed on a yamaha + klipsch setup a couple of years ago that had the same problem and an owner with known hearing damage partly from working in the coal mines down under as a youngster and partly from a diving mishap. The psychoacoustics of it is that it is a treshold of audibility vs. masking issue, quite possibly caused by the movie soundtrack being mixed somewhat louder than you prefeer to listen. Also putting the vox in a center loudspeaker as planned in the mix will reduce the temporal smear of your room, that too leads to consonant loss just as does the masking from the music and effects tracks. That explanation may be more helpful to you than an exemplification of it, but there are other people out there who read what we type here on all those "forums" that are just a clandestine and illicit echo of usenet. Kind regards Peter Larsen It doesn't matter unless it matters. Maybe they mixed with a center dialog speaker on Avatar and really made an effort to make that center channel happen and keep dialog to a minimum elsewhere. I don't know about illicit, but clandestine, prolly. HNY!

(in article ): with the center missing? How stupid could I be, Scott? No, the system is configured for no Dialog speaker -- center front is split through left and right front. Will, I don't think Scott was saying you were stupid. The pinwheel of different multitrack PB options on my receiver amp do amazing things to plain old dialog. If you have one, give it a spin and see if another seting works better.

We're trying to help. You don't want it. Game Over. They mixed the movie differently or encoded it differently. That's pretty much it.

(in article ): I started watching the "collector's" cut of "Avatar" last night, after having watched the terrific Blu-ray of "King Kong". (The films are thematically similar.) The dialog sounded rather distant and lacking in presence. Raising the overall level a few dB fixed this, without causing the music and effects to be unduly loud. (I do not use a Dialog speaker, and I don't generally have this "problem" with other films.) Would anyone care to comment on this? ------------------------------snip------------------------------ You're just noticing this now? The problem is endemic to the business. Many, many, MANY films are mixed in such a way that their dynamic range is too wide for home video. This has been an issue for a decade or more. If you're not using a center speaker and watching it in 5.1 surround, then you'll never hear it in the way the re-recording engineers intended. This will be a compromise that will grossly affect the mix (as Geoff comments elsewhere). One reason why a 4-speaker layout will not work is that you're going to run into unpredictable phase cancellations, which will tend to affect EQ and balance. I agree with Peter's comments: get a center channel (even a non-matching speaker), bump the center level up a dB or so, and see how that sounds. BTW, if you think this is bad, listen to the remixes on the STAR TREK shows and some of the older Bond films done for Blu-ray. Way, way, way too dynamic for me. There are many, many home video mixes that have this problem, but the vast majority of them are reasonable; it just happens that you discovered this with AVATAR, two years after the movie was released. In my opinion, the issue is not so much that the loud sounds are too loud; it's that the quiet dialog passages are _too low_. This is bound to wreak havoc in a 4-speaker system. Les Cargill commented: I believe it is a consistent and repeated process failure. They mix 'em with the monitors up too loud, to make the explosions more prominent. ------------------------------snip------------------------------ It's not as simple as that. There are standard set-up parameters and program level practices established by SMPTE, the AES, and the CAS, typically based around a program level of 85dB. Read the extensive discussion on how films and TV shows are mixed for surround at this link: http://www.gearslutz.com/board/post-...andard-mixing- levels-movie-theater-dvd-broadcast-tv-commercials-etc.html The ITU and other organizations have more recently come up with new ways of measuring apparent loudness and dialog levels, so one hopes that this problem is becoming more understood. Here's a technical paper that explains their methods: http://www.itu.int/dms_pubrec/itu-r/...201103-I!!PDF- E.pdf Certainly for broadcast (and home video), I think the mixes today are generally coming more into line with reality than they were, say, five years ago. In particular, TV mixes are fine and are carefully checked for compatibility, both with a 2-channel downmix and a 5.1 surround mix -- and sometimes, they even check mono compatibility as well. --MFW |

I'm not sure what you're talking about. All my equipment -- including my SACD player -- is set for four large speakers, no Dialog speaker, and separate woofer. There are not alternative options for my speaker setup. |

Well, as you have a volume control, there's little distinction between the two. Regardless, I felt that, even with the dialog set for a "natural" level, the loudest passages were loud enough to be exciting, without breaking my ear drums. Whoever did the mixing judged the relative levels very well. |

The problem is endemic to the business. Many, many, MANY films are mixed in such a way that their dynamic range is too wide for home video. This has been an issue for a decade or more. I have very good playback equipment, so this might not have been apparent to AAAAAAAAAAAAAAAAAAaaargh! Yes, you've got wonderful equipment (you forgot to mention the planar speakers one more time). You're a professional writer (god knows why), and you're rarely ever wrong (hehe). You're trying to play 5.x material on a 4.x system. Numerous suggestions have been given, including deploying a center channel speaker, and learning how to adjust the settings on you (very good, of course, very good) equipment. But you just don't seem to get it. If you're not using a center speaker and watching it in 5.1 surround, then you'll never hear it in the way the re-recording engineers intended. That pretty much goes without saying. Duh! (D'oh!) I don't altogether follow. If the Dialog speaker is used solely fordialog, and Lf/Rf solely for music/effects, how would splitting the dialog to Lf/Rf create phasing effects? There are three front speakers: L, C, R. The arbitrary assumption that the center is only dialog and the L and R are only for music and effects is an oversimplification, and is frequently not a valid representation of real-world material The material is mixed for three front channels, and you've only got two. If your (very good, of course, planar, of course) speakers are so wonderful that you can't deploy a third front speaker, then you should learn to dick with the settings on your (very good, of course, very good) surround processor. If that doesn't work, maybe your very good equipment is not up to the task, or the I'm-almost-always-correct audio writer doesn't understand the format or his own equipment. If you spent as much time reading and understanding the suggestions that have been made, as you've spent complaining that people supposedly don't understand your expert writing, you might have perceived a clue. The "quality" of the system is not the issue. The planarity of the speakers is not the issue. The issue is that the system does not implement the format found in the source material, so manipulating the processing is required, and different manipulation may be required with different source material. If you tried to reproduce stereo audio with a single (very good, planar) speaker, it would probably sound screwed-up as well. /uncloak |
