Loudness Correction in Equaliser APO - Natural Sounding Audio

Ғылым және технология

Through this quick tutorial, I will show you how to properly get the right level for loudness correction within Equaliser APO.
It's a crucial EQ technique to correct loudness, it makes a crucial difference to how you listen, especially when you don't want to be listening at reference volume! It's also a crucial part of active loudspeaker design and makes your design stand out much more!

Loudness is all about how our hearing changes at different volume levels, loudness compensation makes audio sound natural at any time you want to listen below the reference level. Given that the reference level is very loud, this is pretty much crucial to great-sounding audio!

    You guys actually don't need any measurement tools. works perfectly on my 5.1 surround setup. Just mix and match those knobs at your desire audio you perceived. You can also look at the graph👌👌👌👌 Works along with PEACE APO too.

    I need to create a follow-up. There's a reason for manual methods... Also, feel free to just tweak until it sounds right to you. That's totally valid. It's just not necessarily accurate. 👍

    I wanted to add, you're probably right in terms of adjustments as an end-user/consumer of the content, this is because unfortunately the mixing/mastering isn't always done properly and doesn't always follow these loudness guidelines, because of this you may just be better off doing it by ear, unless you know it was properly produced or don't mind a little variation. However for mixing and mastering, it's important to have loudness set up correctly for the platform you are distributing to so that you can more accurately mix and master your content for your user and how they'll be hearing it.

    ​@@kalumanderI'm ok with that. People can still use the standard method if they'd like. But given the fact that based on what the audio source is, netflix, KZread, Blu-ray, changes what the reference volume is, going through REW just let's the user actually know what they are targeting. Thanks for the feedback though 🙂

    Is this "Loudness correction" feature better than windows "Loudness Equalization" feature??

  • @Elliott-Designs

    I'd say so, as unlike the windows feature you're able to adjust it for different content (as different contents have different targets even if -14dbFS is meant to be the standard for streaming, it's not always followed, particularly for Netflix and Disney plus I believe. Don't hold me to this, but I believe I may remember reading a few years ago that all the Windows "loudness equalisation" tries to do is make it so that volume differences between applications isn't as prominent. I believe it must act as some kind of normaliser, unlike this method which makes the audio sound the same (bass, mid, high balancing) at different volume levels given that the way our hearing works is different at different volume levels.

    So would this make lower sounds higher and high sounds lower? Meaning in a game it will heighten footstep sounds and make explosions lower? Aka what loudness equalization does

    Close. As volume increases low and high frequencies become more pronounced (not just low frequencies), the inverse as volume decreases. What this does is attempt to make it so that things don't sound different at different volumes as it compensates for how our sensitivity to different frequencies changes with volume. Does that make sense?

    It doesn't work for me. It doesn't equalize youtube sound. Windows volume is set to max. But your video is as quiet as a louse. The other video is loud. It's a crap. Because with how I install it. The lodnes compensation button has disappeared in windows. I can't even avoid this problem. Don't you know any software that has parametric eq and loudness equalization works? Realtech's hd eq falsifies the sound in the entire range, it's crap, unusable crap.

    If it's not working for you, likelihood is something went wrong with the initial install. You can head onto toidsdiyaudio.com, there's a forum on there where I'd be happy to help, but there's absolutely no need for such language, I'm making informational videos to help people. If my video is too quiet for you that's because I use a wide dynamic range for better audio quality. Perhaps I shall compress my audio in future videos for those that don't have the volume capability. Thanks for pointing that out (although you could have done it a little more politely). Not sure what you're referencing with the Realtek stuff, perhaps if you could rephrase that part? This program is one of the best for software loudness equalisation and EQ. As for not equalising KZread sound, it won't be equalising any sound (not just KZread). The EQ functions systemwide. Hope this helps 👍

    @@Elliott-Designs It's not the APO EQ that doesn't work, it's just the equalization module. The equalization function works perfectly in the realtech HD menu! Equalizes all sounds, including your video. BUT. If I activate the APO software, the equalizer check box disappears from the realtech HD menu. The APO software blocks the realtech sound effect modification menu. The consequence: I can't adjust compensation either in Windows or in APO. It is not enough for me to only be able to set EQ schemes. Due to videos with different volumes, an equalizer must be turned on. But if I want to listen to music, it must be turned off. That's my problem.

    @@retrobudapest Ok, I see now. Yes, with EQAPO you will not have access to the realtek EQ as well as EqualiserAPO's EQ, this is because EQAPO embeds itself around the realtek driver. Luckily, you'll have the same equalisation abilities inside of EQ APO (parametric and graphical EQ). Actually, you mention videos with different volumes, is perhaps the feature you are missing called compression or normalisation? Either way, all videos on KZread should be fairly similar in volume level. They are all equalised to a loudness of -14LUFS. Going from program to program is a different issue of course. That requires several different preamp sections in EQAPO that you have to turn on or off depending on what platform you are using. I have a good write-up of integrated loudness of different video and audio sources on toidsdiyaudio.com if you wanted to implement this. You mention it not being enough to just be able to "set EQ schemes", what do you mean by this, what is missing? Hopefully I can try and help solve this for you.

    @@retrobudapest KP, you are misunderstanding what the "loudness correction" feature in Equalizer APO is for. It is not like ReplayGain which normalizes loudness between tracks, albums, etc. I don't know of any software that would do that *between* Windows applications. I'm amazed your Realtek software even had an option for that. You might have a tough time finding something that works. You probably just need to ride the volume knob all day like the rest of us! hahaha

    @@rofii_vt Reference level and reference offset are do the same thing, but in the opposite direction. Let's say your program is mixed to be listened to at 75dB in the listening position (when playing pink noise at -14dB (14LUFS), so you do your test with pink noise at -14dB with windows volume itself at max, that tells you should set reference level to 0. Now let's say it measures 78dB instead, that's 3dB too loud, so what do you do? You set reference level at -3dB, because your reference volume is 3dB quieter than your max volume. It's the same for if you're below your target e.g. 72dB, then at max volume you're 3dB too quiet, so you set reference level at 3dB, because the reference level is 3dB louder than your maximum. The second knob, the offset, is purely for convenience. Let's say we already have reference level set up so we never have to touch it again, but this other program material has it's loudness described as 26LUFS at 75dB (75dB when playing pink noise at -26dB), we originally calibrated to 14LUFS, so if we do 26-14=12. That tells us this new programme material has 12dB more difference between our maximum/peak volume and our average/talking volume. This means the target has moved so that the calibrated listening level is 12dB quieter for the same setting. So we can adjust the reference offset to -12dB to temporarily compensate. Attenuation is simply a factor that describes how much loudness correction you want to apply. If at 1, it applies all of it, the closer to 0, the less the effect is applied.
