Further to Mike Head's post: "On screen VU meters for you", I had asked about a "digital peak hold" meter. My intent was, to be able to "normalize" BIAB files.

VideoTrack suggested a program called Orban Loudness Meter.
I checked that out but it was a bit more than I needed.

I've since figured out that, for the BIAB files that I need normalized, I have already converted to MP3's using Audacity, plus I have a bunch of other MP3s I've "collected" from various internet sources (some bought, some free).

I came across a program called "MP3Gain" http://mp3gain.sourceforge.net/
that seems to do what I want.
(Tutorial here: http://mp3.about.com/od/tutorials/ss/Normalize_MP3.htm#step1)

If anyone else has experience with this program, I'd be interested in hearing about your results.

Thanks!
