"I have a ton of various music files on my machine that are in
various states of migrating from .mp3 to different formats. The
primary reason for this is because of the issue of licensing
between Linux and the MP3 format. And although there are GUI tools
to do nearly every job you need, there are times when the command
line is still your friend. For instance, say you want to do batch
jobs – the command line is good for this. Or say you want to
(for whatever reason) secure shell into a remote machine and then
convert your files. For whatever reason you need, it’s good
to know that the tools are available for the job.
"The tools I am talking about are mpg123 and mpg321. Although
mpg321 claims to be a drop-in replacement for mpg123, I still
prefer to use both tools (the former for converting .mp3 to .wav
and the latter for converting .mp3 to .ogg). And in this article
you will see how simple it is (using the command line) to convert
these file types."
