      @@curtisjudd I'll clarify. Television shows and movies are produced for release on their platforms. Movies may be adjusted before airing to adhere to LUFS/LKFS guidelines too but TV stations often compress any program content. They also visually process shows too which is why TV is a terrible place to watch a movie or TV show. These are done within guidelines (which are minimum specs) to make it a better experience on TV.
      Movies and TV shows are produced to look and sound a certain way and if it were possible to air without changing anything, it would be ideal for those of us that worked on it but there are broadcast and cable cast regulations that must be followed. I worked on a show that aired on USA and me and the sound mixer heard all kinds of distortion and compression when the show aired because that's what the station does to all program content. My mixer recorded the show and sent it to post and asked them about some of the things he was hearing. They responded back that their master didn't sound like that and this was common in TV. If we bought the DVD of the show, it would sound better. He was right.
      It's been over 2 decades since I worked at a TV station and that was pre-HD but I'm sure stations still have safety measures to make sure audio doesn't go out too loud or that dark scenes don't go too dark.
      Commercials, on the other hand, want to be noticed and may do tricks to get attention. Extreme compression is one truck they'll use so that if you're watching a late night show and doze, you'll wake up and watch. Another trick they'll use it playing the A-weighting curve - boosting the crap out of mid and higher frequencies because you hear them better. Really annoying infomercials may even apply aggressive low and high pass filters so that there's more headroom for an annoying presence boost (for example). Commercials don't have to be cinematic masterpieces, their goal is to sell a product so if that means using tricks to sound louder and be noticed, they will. Commercials aren't immune to processing but aren't afraid of playing games.

      Hahaha, thanks for the wealth of input. Your information coupled with what Curtis conveyed tells me that by sustaining certain loudness levels with very few quiet moments, infomercials and such can be perceived to be louder but still fly below the standards that mainly account for dynamic range differences. Am I understanding you both correctly?

    • @SoundSpeeds
      @SoundSpeeds 3 года назад +2

      @@insanejughead I think I understand that and I think that's right. Curtis said sustained loudness over time is perceived louder than audio with more dynamics and that's 100% right. What I added is that sometimes commercials and infomercials will use tricks to maintain loudness for the entire time and/or boost frequencies humans have a more difficult time ignoring while cutting those we may tune out.

    This has always been one of the most confusing things about video production. When I made my first TV commercial, they kept rejecting the video for two reasons... the loudness and the luminance / whiteness levels. The same side of two different coins. I wish I saw this before all that trial and error. I would love to have a button in Final Cut Pro that lets me just click a dropdown to use the correct levels for various platforms.

      I totally agree. I finally got frustrated enough with FCP and bought a copy of Izotope RX8 (though there are many other capable tools as well) to normalize all audio before importing audio separate from video. RX8 has output presets for broadcast, streaming, podcast, and more. Adding this step takes a little longer at first, but knowing that my audio levels are correct for output has reduced my level of anxiety with the finished product. No affiliation with the company, just a satisfied user.

    During my live streams I have game audio from a game like Call of Duty Cold War, music from Epidemic at 320 kbps and my voice from me speaking into a SM7B all mixed together in real time via my GoXLR mixer.

    • @curtisjudd
      @curtisjudd  3 года назад

      Hi Ken. Yes, good advice from my point of view. The AES recommendations are, in a nutshell:
      It is recommended that the Target Loudness of the stream not exceed -16 LUFS: to avoid excessive peak limiting, and allow a higher dynamic range in a program stream.1
      It is recommended that the Target Loudness of a stream not be lower than -20 LUFS: to improve the audibility of streams on mobile devices.
      It is recommended that short-form programming (60 seconds or less) be adjusted by constraining the Maximum Short-term Loudness to be no more than 5 LU higher than the Target Loudness: This ensures that commercials and similar short-form content are consistent with the stream loudness.
      It is recommended that the maximum peak level not exceed −1.0 dB TP: to prevent clipping when using lossy encoders.

    Hey Curtis thanks for this. Been a real issue for me.

    • @curtisjudd
      @curtisjudd  2 года назад

      Thanks Dennis. First, note that RUclips’s numbers are relative to their chosen target of -14 LUFS. So my videos are generally targeted at -17 or -23 LUFS depending on whether I’m reviewing a microphone or recorder (-23 LUFS) or covering something else (-17 LUFS). The reason I target -23 for mic and recorder reviews is I want viewers to hear how they sound without any processing, especially compression, and that is generally possible at -23 LUFS. Once you push the loudness to -16 or -17 LUFS, compression is generally required. Hope that makes sense.

Because its a different thing when you listen to music or educational podcast shouldnt they have something like a vaiable loudness for different categories? Whats your opinion? Thank you!

    • @curtisjudd
      @curtisjudd  3 года назад +1

      Remember that Spotify started as a music streaming service. They did what I think is a wise thing to help manage the loudness wars which have been plaguing the popular music world for a few decades now: Set a reasonable loudness standard of -14 LUFS. That's great for popular music. But in my opinion, it is not as great for material which consists mainly of spoken word content. Spoken word audio tends to sound a little too compressed at -14 LUFS in my opinion. I believe that -16 LUFS is a better middle ground - loud enough for playback on consumer grade equipment in poor listening conditions, but not so loud that there's no dynamic range left. I wish they would use different standards for different categories. I think an argument could be made for orchestral/classical music. That isn't going to sound great at -14 LUFS.

    In the home audio world, some of us remember when "loudness" referred to a special EQ control based on the long historied Fletcher-Munson curves that describe human hearing as it relates to the perception of loudness. The usual take-away for mixing engineers was to mix a track so it sounds its best when played back at high volume. Hence the phrase, "crank it up, dude", right?
    Thanks for the link to the ITU document. Great discussion in it about true peak vs peak-sample metering -- certainly worth being aware of.

    Thanks for info, I had aimed at -12 for sometime for internet radio believing tidal/spotify were at that range looks like changed around 2017. Although looks like I am the only one submitting to station with any consistent level as other shows a bit louder or up and down. Nice to try and pretend I'm doing it roughly correct. 😂

      Yes, turns out that they only enforce the upper loudness limit (-14 LUFS), and not anything that falls below that.

    Audible.com insists that there audiobook files be delivered between -18 and minus 23 RMS seems like a pretty wide allowable range, they only use RMS not the lufs I guess it's something they've been doing a long time and haven't really seen a reason to change although the audio pauses ie blank spaces audio books are typically much shorter or should I say more regular been something like the audio on TV so maybe that makes it more accurate closer to what lufs might appear to be?

    • @curtisjudd

    Yelp! Going back some time now, on one of your videos you recommended -23 LUFS (LKFS in Resolve) as the level to normalise your audio. I've been doing this for some time now to provide a consistent audio level to all of my videos. Should I now change that to -16?

    • @curtisjudd
      @curtisjudd  3 года назад

      It depends on where you publish or broadcast. For broadcast TV, they have specific requirements. In the EU, that is -23 LUFS. For the US, -24 LKFS. For online, I generally recommend -16 to -17 LUFS.

    Thank you for the recommendation at the end !
    I have always been wondering how loud should VO and dialogues be (it's a mess on RUclips as everyone sounds very different).
    What is your recommendation for the loudness and dynamic range of masters for videos with more tracks (including voices + music + atmos and background + FX)? If not pushed to the limit it could be perceived as lower quality, isn't it?
    Do you recommend the same loudness for the web and for higher quality watching (let's say high end TVs and more cinema like systems with proper sound) as we have no limits?
    It seems that the mindset for mastering music and mastering sound for videos is pretty different.
    In music, many engineers still push loudness pretty far, even if the loudness war has evolved a lot.
    Most of modern music is between -9 and -5 LUFs if you take the original masters.
    To some extents we like to hear compression (and limiting) and use hard clipping. Some music is made to be loud.
    I assume that this might not be pleasant in a film or might kill the realism?
    PS: It is not really the same topic (even if it is linked at some point) and I still need to explore your channel (maybe you have talked about it); but how do you approach compression for VO and dialogues?
    So far, among all the RUclips content I have seen, related to sound for videos; they never enter into details about compression.
    They only make a basic use of compressors to control peaks and retain some dynamic and once in a while they dare to talk about de-essing .
    So I am wondering if you guys use compression a lot (or if is not so useful compared to music where vocals always need to take their place among many elements), for example:
    - for volume shaping: emphasizing the attack in order to make words more audible
    - use opto to bring some more body and sustain while preserving the attack (I guess it would require a good cleaning as it can bring up the room and noises)
    - use upward compression to bring thickness
    - use sidechain (I guess the answer of this one is pretty obvious, even if I haven't seen anybody talking about it)
    - multiband (I guess it depends on the recording and the issues to be fixed)
    I know I ask a lot and I do not expect to get an answer for every point. Thank you for reading already. haha
    And if anyone else reading this have answers for me, I take it. :)

    • @curtisjudd
      @curtisjudd  3 года назад

      Hi Sonny - I would apply the same recommendations for video or film - the loudness target depends on where the audience will view/listen to the video or film. On the web/mobile, I'd target -16 LUFS. RUclips will allow you to go to -14 if you are ok with less dynamic range but that often sounds too crunchy for my taste. For theater, I'd target -23 or -24 LUFS where presumably, the theater will be sound isolated from the outside and will have a high quality playback system so you can take advantage of wider dynamic range.
      Interestingly for music, the streaming services and RUclips take those ridiculously mastered tracks and push them back down to -14 LUFS. You can see it peak out well below 0dB if you have an audio interface with a decent meter.
      I use compression for VO and dialogue in video to achieve my target loudness levels - just enough to tame the transients down so I can push up to -16 or -17 LUFS. My approach is pretty straightforward and the result usually adds a bit of thickness. I generally use a fast attack and 500ms or so release so it doesn't pump. Usually I keep the ratio around 3:1.
      I approach it something like this: ruclips.net/video/lHNhxGojFRU/видео.html

    So why not target -23 or -24 LUFS? That way those of us who watch TV on the computer (or those who watch RUclips on a TV set) would not have to keep adjusting the volume every time we switch from watching TV to watching RUclips and vice versa.
