I have been using https://github.com/jiixyj/loudness-scanner to scan
audio file and apply replaygain tag according to ebur128, although afaik
there is no support for applying the gain to the file itself. You could
apply the gain using sox and some scripting (theoretically).
There is also http://r128gain.sourceforge.net/#apply that is said to be
able to apply the gain in combination with sox, I haven't tried it
though.
