1 Mplayer-af volume=-10 *.mp3
The range of volume can be-200 to +60.　-200 is mute. and +60 is noise.
When each song is on the air, the volume is reset to the volume at startup, and you can't improve the sound when it's playing.

Just started with the default volume. In this way, the volume does not change, only when you press 0 or 9.　will not take effect. The maximum volume becomes the original 10%, that is to say, you now 100% of the volume is only 10% of the volume of the original
When you change a song, the number you dial with 0 and 9 will revert to the default volume.

3 Mplayer-af Volume=-10-softvol-softvol-max *.mp3
