Well, it is quite a task. The only reason git doesn't win the
longest-man-page-contest is, that its man page is spread over several
ones. ;-)

By "diagonally" I mean: skip unimportant stuff (details you're not
interested in), but try to get an overview: what is possible (not how!),
what is explained where, ...
I find this superior to just blindly following online tutorials and code
snippets gathered from forums, mailing lists, etc.

but back to the actual topic:
There are some syntactic errors in your command:
<cite>
sox --combine sequence /filepathhere sox -t wav - -t oss /dev/dsp
</cite>
If you try to invoke sox twice (which you'll need), you need to separate
the two commands somehow (e.g. pipe "|" the first ones output to the
second ones input, give one as a special input to the other via naming
one file "|sox ...").
Also I think, "sequence" is not what you want. This will play the first
audio, then the second, and so on. You'll need "mix" or "merge" and a
remix-effect.

If you want to find out, what your mic is, try some more simple command like
<cite>
rec test.wav trim 0 10
</cite>
and look, if test.wav contains something real. It's always a better idea
to start simple and enhance than to start complex and debug ;-)
