How does it cope with a group of files including an acoustic ballad

It'll probably end up making the hyper-compressed rock song pretty quiet.

Pretty sure this one doesn't clip. There's a lot of information at
the web site. I recommend looking at it. Been a while since I read
it but seemed like a well thought out approach at that time.

I'm interested too. I have over 42,000 mp3's now, and I have to ride levels
constantly.

Sony Soundforge Batch Converter will apply anything you like to whatever
files you specify..

Like ANY other sound editor. Unfortunately, it will re-encode your
MP3's, which is a BAD THING.

That's why to use MP3 Gain. It does NOT re-encode your MP3's. It
only writes a volume play back level to the header which can be
removed at any time.

Thanks for your comments on this software... I'll have look at it, though I
don't do a lot of MP3-ing.

Mp3Gain has three ways of adjusting the gain; 1 is called Album Gain, this
will change the average gain of the album to a certain user defined level
(default is 89 db) so some songs will be higher than 89 and some lower but
the average for the album will be about 89 this maintains the relative
volume between songs; 2 is track gain, this will increase or decrease all
songs to a user defined gain, so all songs are at the same volume; 3 is just
adding a constant gain to all songs, no analysis is done.

For the above example, using album gain you can increase the volume of both
songs but the relative volume between songs will remain the same, using
track gain the volume of both songs will be about the same. Setting the
gain too high will cause clipping. MP3Gain will show you which songs will
be clipped prior to applying the adjustment.

Unfortunately that volume reduction is probably achieved digitally by
just throwing away bits, which is a bad thing. Anyway do you WANT
everything reduced to the level of the quietest? You then have to
apply more amplification, bringing noise levels up.

I had a look, and I can't see how the device works without modifying
dynamic range - but even if it works by lowering... you have another
valid 'yuk' point.

Simply put...

1. Find max volume among all songs
2. "Turn up the volume" in all others so their max is the same as the
loudest.

Won't work - can't work. If you have a mixture of music, then peak
levels as related to average loudness will vary wildly. The loudest
sounding will have highly compressed dynamics, with most of the tune
crammed against the limit. If you try to increase the levels of all
the others until they sound as loud, they will all be clipped to hell.
