[2.1] Customizing the Ambient Sound zoom fade

[Phnod]

I couldn't find any notes of this in the 2.1 changelog, but I've noticed that ambient_sounds (The background music) now have a sort of lowpass filter applied to them when zooming out, cutting out the high frequencies. (Maybe it's the one of the same filters that's applied to everything else?)
I went back to check 2.0 and it's not there, the music remains at the same level at any zoom.
I couldn't find a setting to change this in 2.1, could we get one? With how much I zoom in and out, I'd prefer to have the music be unaffected by the zoom level though an option like a checkbox or exposing a float multiplier of how much it affects ambient_sound, even if it's hidden in "The Rest" page.

Music (AmbientSound) is not affected by the zoom level based low pass filter.
If you think your music is affected, create a bug report including a short clip showing the issue, your config file and log file.
