The only comment I’d make is that Spotify for example will change the sound of your track if it is at less than -14 LUFS and needs to be louder. In their own words:
Negative gain is applied to louder masters so the loudness level is at ca - 14 dB LUFS. This process only decreases the volume in comparison to the master; no additional distortion occurs. (...This is exactly what Cs70 was saying)
Positive gain is applied to softer masters so that the loudness level is at ca - 14 dB LUFS. A limiter is also applied, set to engage at -1 dB (sample values), with a 5 ms attack time and a 100 ms decay time. This will prevent any distortion or clipping from soft but dynamic tracks.
Thanks, didn't know! Even better :)
I _think_ I remember that one of the major platforms (YouTube?) doesn't but I am not certain, and these things can change one week to the next as new features are added in these companies continuous development cycles. So maybe they all do now..
