Wrapping MP3s

There is a now-standard Linux utility for merging MP3 files named mp3wrap.

Unfortunately, it often plays havoc with the duration of the resulting file. I finally found what fixes this.

The utility ffmpeg is the needed tool, and the command is:

ffmpeg -i FileName.mp3 -acodec copy NewFileName.mp3

Then delete the old file.

(While searching for the solution I also came across Ubutnu hotkeys and themes, which I do not care about but some of you might enjoy.)
