US Bans Loud Commercials

bs0d3 writes "On Tuesday, the FCC passed the Commercial Advertisement Loudness Mitigation Act, or CALM. It's a law that states all commercials must run at the same volume as network newscasts. The same applies to network promos. The responsibility falls on cable providers like Comcast or charter. The law will not take effect until next year which leaves it plenty of time to be challenged in court by cable providers or advertisers."

      All of the comments so far are "it's about time," so I'm just going to respond to the first post I see.

      There already was a standard requiring commercials to limit loudness. A commercial could not be louder than the program it was accompanying, which meant it could not be louder than the loudest point in the programming. What that meant is if there was a single gunshot in an hour, your commercials in that hour could be very, very loud. Also, loudness was not weighted. High-pitched ringing and speaking at the same level were considered equally loud, even though human hearing is skewed (A-weighting) to perceive speech as inherently louder.

      So what this really does is 1) re-define what constitutes "loud", and 2) give the process some teeth.

      The bigger problem is working around the requirement by (ab)using the principles of the psycho-acoustic modelling of sound, like with A-weighting and equal-loudness contours.

      http://en.wikipedia.org/wiki/Equal-loudness_contours

      Essentially, the human ear's perceived intensity at different volumes is frequency dependent. One trick is using an auto-tuner to "shift" audio to nearby frequencies so that the overall loudness (as measured by an ideal microphone) is within the acceptable limits in the proposal, but the human ear "hears" them as if they are louder than they really are.

      Correct, it's not "Normalize". That algorithm seeks the highest peak in the audio, then raises or lowers the TOTAL GAIN to bring THAT PEAK to the preset level. Here is the caveat. You can have an audio file that is -50 db (barely audible) with a single "clunk" (like the mic got bumped) at 0 db. If your "normalizing" to -6db, then it's going to reduce the gain of the ENTIRE FILE by 6db, leaving your desired audio at -56, with the single peak at -6.

      What you want to do, is technically known as DYNAMICS COMPRESSION. This is a variable gain adjustment, on-the-fly. Radio stations use "audio processors" to do this in realtime. With digital audio, the process can be MUCH more precisely controlled, since it is NOT in realtime. With proper dynamics processing, you'd have that -50db audio raised to at least -20, and that 0db peak dropped to -6. Yes, you can "crank it to 11" by having it raise the -50 db audio to -6, and bring the 0db down to -6 also... but with too much gain increase, noise is raised, as well.

      Dynamics compression is what those LOUD commercials are using. If you open the audio in an editor program like Audacity, it looks almost flat, with minimal hills and valleys. You will also see this on MOST modern music. The compress the daylights out of it, to make it all sound LOUDER. It works, too... having 0 db of dynamic range in audio sounds quite loud, and becomes fatiguing to listen to for any length of time.

      What would REALLY be needed, is a "smart" detector that not only examines peak amplitude, but also the AVERAGE. If the average is always high, then the gain will be dropped proportionally. It would take some doing to make a system that could do this reliably. I have a TV with what they call "Equisound", and it is absolutely DREADFUL!

  28. How to measure loudness by steveha · · Score: 5, Informative

    Since this is Slashdot, I'll share some details on the problem of measuring loudness.

    Loudness is difficult to measure objectively, because loudness is what a human experiences when listening to audio. Intensity, on the other hand, is easy to measure; just get a sound level meter.

    Why is loudness different than intensity? Because the human auditory system contains a natural filterbank that divides incoming audio up into multiple bands, and then applies an exponential scaling function to each band. Old books and papers call these bands critical bands; I think the more modern concept is ERBs.

    For sounds that hit only one band, such as a pure sine tone, the intensity of the sound is a good approximation of loudness. But sounds that hit multiple bands scale roughly linearly in the number of bands hit. I'll give an example.

    If you generate a pure sine tone at power level X, and then generate two sine tones each at power level X/2, then the measured intensity will be identical. However, if the two sine tones are in different bands, the loudness will be nearly double.

    So, as a rule of thumb, the more frequency bands a given sound hits, the louder it is at any given power level. Something that sounds like white noise will be louder than something that sounds like a clear bell tone or a single flute note.

    The people who make commercials know how to game the system. I'm pretty sure that there were already limits on measured intensity of commercials, but that wasn't enough to solve the problem.

    Imagine you are driving along, listening to a radio show. Maybe talk radio, maybe NPR, whatever. You have the "volume control" knob on your car radio set to a comfortable listening level. The radio show only has audio at typical human speech frequencies, and isn't trying to sound loud. Now comes the commercial, which smears its audio all over the spectrum; it puts processing on the voice, with reverb and stuff. "Sunday Sunday Sunday-y-y-y!!!! M-m-monster truck demolition derby!!!" or whatever. It's not your imagination, it really is louder. But a sound level meter might say it's the same as the radio show content, or only slightly higher intensity level.

    The company for which I work (DTS) has a solution to the problem called "Neural Loudness Control", and there is a white paper available that really goes into detail about this stuff, so you don't need to stop with my lame explanation. NLC has a full "loudness model" that approximates the human auditory system when computing a loudness metric; but it also can operate in a mode that follows the new standard.

    Also, here's a PowerPoint presentation by JJ Johnston about loudness vs. intensity.

    So the new standard, 1770, is a pretty easy-to-calculate approximation of loudness. You apply two filters: one that simulates the transfer function of an average human head, and the "RLB weighting curve"; then compute mean-square energy on the result. This is simple enough that nobody really has an excuse in the 21st Century that it would be hard to comply.

    I'm a little worried that it is too simple, and there might be ways to trick it. For example, it doesn't seem to handle audio that is smeared across multiple bands to make it sound louder. But I'm not actually working in the area of loudness measurement, and from what I've heard, 1770 works okay for most stuff. It's better than no standard.

    And on the gripping hand, 1770 is the law now.

    From our perspective, because we agree with what they're trying to accomplish. I don't agree with the means, though, which makes it very bad legislation.

    Just because YOU do not agree with the means does not make it bad legislation.

    We have government for precisely this reason, to restore some semblance of a balance of power between the individual consumer and the corporate giants who feel free to subject you to anything they think they can make you swallow. They are using our airwaves, and our TV sets, to say nothing about our eyeballs, they should follow our rules.

    Your position seems to be you always have the right to turn it off, and any abuse you get is of your own choice. I'm not willing to make that choice. Why should I? What kind of freedom is that? The choice to take it or leave it? Screw that. They can operate by our rules, or operate not at all. Let them take it or leave it for a while. They've had their way for 30 years.

    The flight toward other entertainment channels is already in full swing. TV ownership is declining. People are dropping cable. More males play videogames than watch sports now. The baby boomers, the quintessential TV generation, have begun going on to their reward. Even basic media consumption habits (time-shifting, etc) have changed for good. TV still has more time left than newspapers do, but not much.

    So turning down the volume of commercials now is a bit like repainting the ballroom after the ship has already hit the iceberg.

    I watch a lot of British TV shows, mostly from the BBC. They pay a tax to access the BBC there I believe, and in return they get no advertising. As a result most British shows are better written, better paced and better produced I think, in part because the program has that much extra time to evolve the story in.
    Of course, their series are generally pitifully short for a season (say 6-10 episodes in Britain per season, versus 22 in North America).
    I think that if a big channel were to show its programs WITHOUT any commericals, they might be able to make more money in the end. Of course, I would have to be able to subscribe just to that channel through my cable company and that is never gonna happen. They are too busy matching up crap channels with the 1 or 2 decent ones in a tiering system that ensures I have to spend $100/mo to get all the stuff I want.
    Thus I am killing my cable shortly. I generally run without cable at all for most of the year then sometimes break down and get it hooked up for a few months before realizing that "yes its still pretty much all shit, all the time" and cut it again. There are probably good shows on TV channels that I am not willing to spend an extra $40 to see, but I will never know it because the channels that I do have access too are all full of fucking crap like Survivor, XFactor etc - shit for the mindless masses.
    If I download, I get what I want when I want it and without interruptions. If I like a series, I buy the season as a set and watch it off disks. I own a lot of complete TV series because of that. I now watch a lot of stuff on Netflix mind you, so thats changing too :P

  37. Average?! The average of 1,1,1,1,50 is 5.4 ... by Khopesh · · Score: 5, Interesting

    There already was a standard requiring commercials to limit loudness. A commercial could not be louder than the program it was accompanying, which meant it could not be louder than the loudest point in the programming. What that meant is if there was a single gunshot in an hour, your commercials in that hour could be very, very loud. Also, loudness was not weighted. High-pitched ringing and speaking at the same level were considered equally loud, even though human hearing is skewed (A-weighting) to perceive speech as inherently louder.

    So what this really does is 1) re-define what constitutes "loud", and 2) give the process some teeth.

    Not really. It keys on the average volume of a commercial needing to be the average volume of the show. We don't want averages, we want ReplayGain.

    Averages can be gamed quite trivially. Think of a thirty second ad in which the first 25 seconds contain very soft speaking with bits of silence between lines. The CALM Act affords the rest of the ad the luxury of BLASTING the product's tag line at well over the current maximum volume level.

    What does 'pure anarchy' mean anyway? Serious question.

    Most people haven't looked seriously into the work done in the past 50 years on stateless societies. Some experiments like Somalia show that the fall of the State leads to improved economic conditions (compared to its neighbors, not teh whole world). Dubai implemented private law when they designed their new society.

    Anyway, State-form governments killed half a billion people in the 20th Century between wars and democide, so stateless societies have to at least be that bad before they're dismissed.

    Normalize is junk and it doesn't do what you think it does. What you need is Replay Gain, or dynamic compression if you don't care about dynamics (ie, speech).

    Take a music sample from a cd that sounds low (ie from the 90ies).
    Make a copy of said sample and add a peak noise somewhere (the kind you hear when you unplug/plug your analog line in).
    Make another copy and apply heavy dynamic compression.

    Normalize all three. Puzzled? The first sample sounds loud, the second sounds much lower, but the third one sounds the loudest. That's why normalizing is useless, and you need something else.
