Actually, I did succeed once, but it was terrible work.
First, I tried to cut off the silence at the beginning and at the end of
each song, but that didn't work, because I never knew if a had cut off
enough or not. Then I used MP3DirectCut (on a windows platform) to connect
all the mp3s in the right order to one big mp3 of the whole album (still
with small gaps between the songs). In this big file, it's possible to mark
the gaps and prelisten how it sounds if they are skipped. This way, I was
able to adjust exactly what I wanted to cut off.
But, I think there was still some "information" cut out, too. You have to
cut on frame boundaries and most of the time, you lose information if you
cut one frame off, but you have silence if you leave it in. The album above
was a live album with applause between the songs, probably that's why the
song transitions are inaudible now.
