Supertux: Normalize volume throughout music/ and sound/

[tobbi]

Some sounds and music are louder than others. We should normalize all sound files to a common volume.

Suggestions?

[brmbrmcar]

I'd be worried that it's make some sound/music files too quiet for their purpose, some things are better quieter and others louder. When I hear things normalised I often have to manually change the volume because it sounds 'wrong'.

And maybe while you're at it, make the death sound "less jarring."

[qwertychouskie]

Usually death is pretty jarring. :P Though on a serious note, the sounds definitely need to be carefully balanced (e.g. hop sound a bit quieter than average since you hear it over and over).

[Alzter]

I prefer the M1 death noise, M2's is almost jumpscare worthy.

[busybody42]

I agree with Alzter, the death noise was better in milestone 1. Can we please just revert it to the milestone 1 death noise?

[brmbrmcar]

I've never found it that bad personally. I find it more important to actually be able to hear it over any music/other sounds.

[Alzter]

Maybe make it softer, and quieten the other sounds when it happens?

[busybody42]

I was not saying it was hard to hear, brmbrmcar. It just seems a little... Creepy for a game like this. (THIS GAME IS SOO CUTE!) and I agree with alzter again.

[brmbrmcar]

I never said that you claimed it to be hard to hear. I am criticising you.

[busybody42]

I read it differently, ok? And it sounds like something from a horror game!

[HybridDog]

I think that the death sound should stay jarring. It is your fault when Tux gets hurt. If you do not want to hear it, then play carefully.

I made a pull request for sound gains: #1078

ReplayGain tag usage may be the way for music. It exists to equal different tracks gain more or less. There are two steps:

1. Create RG tags for tracks.
2. Enable tag supplying by decoder.

E. g. what step one looks like for forest subdir (forest-cave are really shooting):

$ vorbisgain -frs data/music/forest/
