Greetings,

I'm in the hunt for Linux-based command line tools that might conspire
to automate this process.


concatenate a string of WAV files

Install sox:

sox in1.wav in2.wav ... out.wav

maximize volume

sox has something (read the man page).
There is a program called "normalize" (no experience).
Audacity does the best job.

automagically split the big honkin file where the level falls
below a given dB level for, oh 3-5 seconds

If the time is known exactly beforehand, sox.
Audacity has sometime for silence detection (no experience).
gramofile does a very good job on vinyl rips.

I guess I'm sort of looking for the audio equivalent of imagemagick (a
package of nifty command line image manipulation tools).

sox.

If command line tools don't exist, is there anything GUI or not in the
Linux world that'll do this? Free of course is preferable. :-)

all free.
