[sclug] [Fwd: Make my mp3s louder]

I used to have the same issue with my MP3s when I used to listen to them while 
walking to work from the station.

These days I just listen on my PC using Amarok, which has a plug-in called 
ReplayGain which allows you to adjust all your tracks so they play at the 
same volume.

I haven't yet tried taking the adjusted tracks and putting them back on the 
mp3 player (I haven't needed to use it lately) but I'm not convinced it would 
work anyway -- I don't know whether the player would pay any attention to the 
adjusted volume settings for individual files. I suppose I should give it a 
try, though.
