A very common use case is that you don't want to waste time using a video editor that requires you to open it up and manually import the video clip and audio clip, then manually delete the old audio track and import the video and new audio. That's too much work and time since we don't want to go through the hassle.
ffmpeg is our solution, all we have to do is specify 3 variables and we're done!

When things go wrong your video is basically unplayable or the first video plays fine and then freezes when moving on to the next. Generally if both videos weren't produced with the exact 100% same settings you will have issues. You can try the basic concat but it often won't work right.
Solution for me:
My example uses 3 videos in total so "n=3" and a=1 to include audio.

M4A is a weird format, so you have to be creative here is a quick copy of what I did.
Basically you need to convert to .wav to make use of them and thenI converted the resulting .wav into an mp3 (nice small file size and basically universally playable):
=======
sudo apt-get install mpg321 mp3gain faad normalize lame
faad "Voice 002 (copy).m4a"
faad "Voice 002 (copy).m4a"........
The problem is that the default of most of these units is set for non-North American phones so the ring sounds like it cuts off and is not sequential.
How To Fix the Issue
Click on "Regional" and make sure you are in Advanced mode.

This command rips the audio tracks to .wav files
*I recommend making a new directory with the name of the audio disc first and executing everything from within that directory below.
cdparanoia -B
Use the lame mp3 encoder to encode each one with this script:
*Note that this will encode any other files ending in "cdda.wav"
for track in `ls *cdda.wav`; do lame -b 192 $track; done........
so in this case we have files named like this:
track01.cdda.wav.mp3 track06.cdda.wav.mp3 track11.cdda.wav.mp3
track02.cdda.wav.mp3 track07.cdda.wav.mp3 track12.cdda.wav.mp3
track03.cdda.wav.mp3 track08.cdda.wav.mp3 track13.cdda.wav.mp3
track04.cdda.wav.mp3 track09.cdda.wav.mp3
track05.cdda.wav.mp3 track10.cdda.wav.mp3
but we want to rename them so they are like "05.........

I would link to the exact product I am mentioning but it's under Products/5.8Ghz because I can't find the exact URL because of their annoying javascript and frames (you'll see what I mean).
The exciting thing is that this unit can supposedly be up to 72mbit, it is NOT line of sight and the range is up to 20miles. I wonder how real world speeds and range would actually be and if it is reliable.

This happened on one of my Ubuntu machines where Igot some kind of segfault on line 21 from LAME at random while encoding MP3s (a second try is fine usually). I've read that it's best to compile it from source and that has solved most issues for people.
Here is my preferred configure line:
./configure --enable-mp3x --with-fileio=lame --enable-debug --with-vorbis
Even with that I got a different error this tim........
