Thanks everyone for your suggestions. After looking at the options I've
settled on using normalize-audio. Reading the blurb on the website, the
programmer has done quite a lot of work to get the 'apparent' loudness
uniform.

What I've done is to store the originals, for possible future needs,
and used this program on the copies. Because I'm using it to actually
change the levels, and in this mode it does the translation my
converting the files to wav format first, I've chosen the option to
convert them all back to ogg, hopefully minimising any problems.

To my ears the end result is very good. All the tracks are now
sensibly in the same volume range, and I can copy them freely to my
various players (all of which understand ogg) with consistent results.
