Youtube LUFS BS?!

As we've all heard there are mastering standards for variety of digital platforms with all different levels and stuff. however it appears to be inaccurate. YouTube does not lower material louder than 13 LUFS as stated in this article:

https://www.masteringthemix.com/blog...fy-and-youtube

I got an order to do a quick remake of a song that was uploaded 8 years ago so I ripped it of YouTube. What I found out is the track is overly compressed peaking at 0db and having up to -7LUFS.


If anyone actually knows what's going on with this and how loud masters YouTube as well as other platforms like.

Bump.

Same WFT here. Don't get it, there are some VERY hot tracks up on Youtube.

Here for the gear
 

If I remember reading somewhere, their sound-check technology is only implemented for stuff that was uploaded after the date it was implemented. So you will find louder older material but will not find any current material that will break the -13 LUFS standard. Hence, the 8-year-old video.

There's plenty of stuff uploaded over the last 12 months, or even more recently than that, that well and truly breaks -13 LUFS.

Hmmm? Maybe it is dependent on where you live?

Seems very consistent (for newer stuff) here in the North of Europe....

I could say the same for iTunes. Just mastered a track at -8rms. Bought and downloaded the track today. It's still -8rms & sounds fine.

-8 dB RMS says nothing about loudness. What LU loudness was the track at?

Of course it does!
Perceived loudness = RMS a-weighted for human ear response to frequencies

Lufs was the same measurement.

RMS is less reliable than LUFS. You can have two tracks that share the same -10dB RMS for example, while to the ear the difference in loudness can be huge. Measuring in LUFS will be much closer to how we perceive loudness.

Agreed. Although I scan RMS & keep a couple different meters open to check things.

My point being, Apple didn't turn my brick down by 5 DB to keep it within their specified LUFS. Perhaps because I was certain there were no overages & kept my final limiter at -.5

Remember that the LUFS (EBU R128/ATSC RP A/85) also uses a "gating system" to avoid "longer" silent passages within the song to be used in the integrated meassurement (start to stop).

So the above is different to a RMS value which is a momentary/real time meassurement only.
