This is a question somewhat related to other one dealing with converting *.flv files to *.mp3 (and I shall reply to everyone in that thread later). The *.flv files which my file has accumulated naturally play back with at different volumes. Adjusting the volume on a per file basis is rather tedious to say the least (at least it will be because they are all going onto a USB flash stick to be played on the car's mp3 player). I know that Audacity has the ability to normalise the volume when several pieces of music are appended together to be treated as one unit to be burned to a CD, but is there some app which will do the same to some 200 individual (mp3) files?
