there are two ways:
http://ffmpeg.org/ffmpeg-all.html#loudnorm (single and two-pass)
http://ffmpeg.org/ffmpeg-all.html#dynaudnorm (seems like single pass?)
that would be really beneficial if it would be included in the near future!
Normalizing audio requires two passes, one to determine the peak audio value and one to perform the necessary filter.
