[MLA] Interesting info about Spotify normalization

[Ian Shepherd]

Interesting, although it would seem to be a very “expensive” way of implementing this, especially now their reference level is lower so the limiter is used less aggressively.

Another interesting Spotify thing though - two people have emailed me to say that their latest iOS versions have three different normalisation choices:

Loud (-11)
Normal (-14)
Quiet (??)

I don’t see it here yet, though.

The bad news is that it will be hard for them to apply improvements to the limiter quality or offer different normalization targets for stationary and mobile devices. Imagine how much CPU power was needed to process all those files...
