The Loudness Wars May Be Ending 294

Hugh Pickens writes "Mike Barthel reports on a technique called brick-wall limiting, where songs are engineered to seem louder by bringing the quiet parts to the same level as the loud parts and pushing the volume level of the entire song to the highest point possible. 'Because of the need to stand out on radio and other platforms, there's a strategic advantage to having a new song sound just a little louder than every other song. As a result, for a period, each new release came out a little louder than the last, and the average level of loudness on CDs crept up (YouTube) to such a degree that albums actually sounded distorted, as if they were being played through broken speakers.' But the loudness wars may be coming to an end. Taking advantage of the trend towards listening to music online — via services like Pandora, Spotify, and Apple's forthcoming iCloud — a proposal by audio engineer Thomas Lund, already adopted as a universal standard (PDF) by the International Telecommunications Union, would institute a volume limit on any songs downloaded from the cloud, effectively removing the strategic advantage of loudness. Lund's proposal would do the same thing for any music you could buy. 'Once a piece of music is ingested into this system, there is no longer any value in trying to make a recording louder just to stand out,' says legendary engineer Bob Ludwig, who has been working with Lund. 'There will be nothing to gain from a musical point of view. Louder will no longer be better!'"

    It doesn't matter to me how loud a song sounds; I can always turn the volume down or use something like ReplayGain to lower the overall level. The real issue is the compression of the dynamic range used to achieve louder sounding music. This proposal doesn't address that: a volume limit isn't going to provide an incentive to expand the dynamic range, since producers are just going to make sure every song bumps right up to the new brick wall.

    Dynamic range simply isn't important to most producers and consumers of popular music now.

    • Mod parent up. Dynamic range (or lack thereof) is a matter of taste, and all this new standard does is give producers a new "brick wall" to run up against. However, since the new wall would be below the level of audio clipping, perhaps it's an improvement in that respect.

      Eventually people will get tired of today's over-compressed sound, and will rediscover the joys of music dynamics. As a (very) small-time songwriter, I can appreciate the appeal of chest-thumping, all-11s sound, for a specific effect. B

      Almost every song, including ones that aren't "loud" are normalized to 0dBFS. The thing is that they have large dynamic range, so their average signal level might be -30dBFS thus making them "quiet" when played back at a given volume. If you limit the shit out of dynamics, it makes the whole thing louder at a given setting on the volume dial.

      That is what people mean when they complain about the "loudness wars." Modern music can't force your system to be loud, I can set my receiver to -80dBref and no sound will be louder than 35dB since that is how it works. The song can't override the volume setting. The problem is that they have no dynamic range, and thus don't sound as good.

      A song that has dynamic range you actually turn the volume dial up on. As the "ref" part implies my system is calibrated to a reference point, in particular the THX cinema reference of 105dBSPL for mains, 115dBSPL for the sub. So when I set my dial to 0dB, that is the limit. That is what I set it to for movies, and get a theater experience. However I don't blow out my ears since the average level in movies is usually 30-40dB below reference. So despite the limit being 105dBSPL, I am usually listening to things in the 65-75dBSPL range. That dynamic range is what makes it sound good, and is what lets big hits, well, hit.

      Music is squashed down, so I have to listen to it at like -30dBref on the dial. ends up being about the same normal volume level, it just means there's no headroom, that everything is the same volume.

      The solution is NOT a volume limit, the solution is to have dynamic range in the files themselves, and put a limiter in the playback device. That way if someone wants it limited, they can turn that on, but you can get full range when you wish.

    • Ever since DVD movies came out the dynamic range became too great. I turn up the volume to hear dialog and then a car horn or dog barking blows me off the couch. The normalizer setting on VLC is not what I want. I want something like this:

      The volume is set to a certain level, that is the level I want and nothing should ever go louder than it. Is that too much to ask for?

    • An RMS volume limit can I suppose to a degree.

      There are purists who want dynamic range and all that and the rest of the people who want to listen to the music in cars or when walking. The solution should be simple - two masters - 16 bit, 44Khz CDs with loudness for the car/walking people and an HD version that is 24 bit, 96 Khz with full dynamic range that listen to music in their anechoic chambers.

      Blu-rays now have that mode, Master-HD or something like that that does uncompressed 24/96 sound. I don't know

      Maybe it's because I'm a dinosaur myself, but I can't stand over-compressed recordings. Few people are aware that terrestrial radio stations often limit and compress their signal before transmitting it - a technique that I think probably began as a way to let the sound stand out against road noise for those who listen to the radio in their cars. The problem is that not only does that limit the dynamic range (how much so depends on the level of compression), destroying the artist's intended contrast between

    You can make all the recommendations and standards you want, but you can't force the studio engineers to obey them, nor can you change the studio executives who are demanding the loudness and writing the checks to the studios. There is a great deal of the attitude in the music industry that "I make a lot of money doing this, and you don't, so my way is clearly right!" So, this movement will probably involve a lot of independent artists. We need pop artists on board.

    If we can somehow start a campaign to get people to enjoy an expanded dynamic range, maybe we can raise awareness of how much better music can sound. Maybe albums/tracks engineered correctly could have another small logo somewhere indicating such a thing - call it something like "HDR Audio" (High Dynamic Range) that makes people think.. "Ooh, HD, this one is better than the one without it" or "HDR is the popular thing in photography, so it's probably good with audio".

    I'm all for more artists and engineers preserving the vitality of their music.

    • But what if Walmart, Target, iTunes, Amazon, Clear Channel, and others all got behind the standard and said they wouldn't sell/play the recordings if they didn't meet the standard. It probably won't happen, but if it did, I bet the studio engineers and executives would follow suit. However, I think the standard would have to not only include a volume limit, but also limit the ability for the engineers to compress the dynamic range. Not sure how easy it would be to police this as some music is loud through

  • Pardon my ignorance, but where in Thomas Lund's proposed standard does it introduce a volume limit on "songs downloaded from the cloud", or indeed on any kind of song at all? A cursory glance suggests the document concerns a means of measuring loudness rather than a means of regulating it.

    • by gmueckl ( 950314 )

      You are right - limits in the levels are missing, but the proposal explicitly states that it is intended as a groundwork for introducing those by defining a baseline algorithm for measurement.

      In the long run, this might only limit clipping due to overly aggressive mixing. The true loudness war caused by compression of dynamic range in the mixing process might not go away as a result. And I don't know how that could even be regulated.

    • A cursory glance suggests the document concerns a means of measuring loudness rather than a means of regulating it.

      If each track comes with loudness measurements, listeners will use these measurements in their playback devices to give all songs the same loudness so as not to have to turn the volume up and down when playing different songs. (See for example players supporting Replay Gain.) Songs mastered near the clipping point will be played back with reduced volume compared to, say, "Money for Nothing" or other tracks off Brothers in Arms by Dire Straits. The idea as I understand it is that labels will self-regulate be

  • Stop unconditionally compressing the sh*t out of everything, and record the dynamics the way the musicians meant it to be heard. Some music is just meant to be in-your-face loud, and that's fine if it is the artist's intent. But dynamic range is often a big part of the emotional impact of music, and to strip that out in post-production is no less egregious than arbitrarily lopping off part of the frequency spectrum, or editing out one of the original band members.

    Of course, the problem is that your average consumer has been trained to like garbage.

    Have you ever gotten into a rental car and taken a look at the audio settings? Invariably bass and treble are turned way up. And what's the first thing people in stores do when trying out a sound system? They turn the volume way up. If it's loud it's good, even if the speakers are clipping.

    And how much dynamic range does your average pop song have anyway? Not much, it's just a wall of noise. And then if you're listening to stuff like hip hop then you're also dealing with low quality samples.

    Wasn't there are article here on Slashdot several months ago about some survey about audio? Researchers found that the majority actually preferred the inferior sound of compressed audio?

    So there's no incentive to improve audio quality. The problem is when this sort of crap spills over to good music.

      I hate the compression ramifications as much as anyone. However, it does make the sound more like a square wave, which is how the C64 SID chip sounds (I'm also a bit of a chip fan). You get particular harmonic overtones which help give richness to a sound. So maybe people are really responding to *that*.

      Obviously the producers are going about it all wrong though, since they get the 'square wave' style, but also lose detail with most of the instruments.

      You can get the best of both worlds.
