Android MediaPlayer volume scale?

Question

According to the docs the MediaPlayer setVolume(float, float) needs to be given a logarithmically scaled value:

Note that the passed volume values are raw scalars. UI controls should be scaled logarithmically.

I was wondering how to do this? Should I just give a log(volume) to it?

Just give values between 0.0f (mute) and 1.0f (full volume)

So the volume scale is linear? – Peterdk Nov 05 '12 at 13:35
No, but this doean't matter. Volume units are decibels, that are logatirmic based (http://en.wikipedia.org/wiki/Decibel). So just use it as linear :-) – rgrocha Nov 05 '12 at 18:45

For Android MediaPlayer.setVolume, searching the web seems to show 0.0f for no sound, 1.0f for full sound.
