With support for the appropriate external libraries compiled in,
SoX can process mp3 jist like any other format.
For m4a, SoX used to use ffmpeg externally; this was very broken,
and thankfully the whole ffmpeg "support" has been kicked out.
I use ffmpeg directly to process m4a files.

Don't know what "laim" is, but you probably lack mp3 support, yes.
How exactly did you install SoX?

The ffmpeg support is no longer there.
What version of SoX are you using?

Most probably that is the case.

My guess would be that you haven't built SoX with support
for these libraries, eventhough they are on your system.
What system is that, and how eaxctly did you install
libmad and sox?
