If you want to archive audio, you should use a lossless audio codec, which
libmp3lame definitely isn't!
Yes, I've 'heard' -- :-) -- that. I thought that flac was just a hobby encoder until I was told that
a specification now exits and that the US Library of Congress is using flac.
What's the origin of these 7 WAV-files and the chapter-file?
A CD I own -- one of about 1500 CDs. I made the chapter file myself.
Did you rip the WAV-files yourself from
a CD? If so, with Exact Audio Copy (EAC) by any chance?
No, I used CDcopy. I used EAC about 20 years ago for a series of audience concert recordings by a
well known German electronic band.
As your intention is to archive this album to one single file, I would highly
recommend you...
1) Rip the CD to one single WAV-file...
Done.
2) I personally use TAK for audio archival, but please consult
https://hydrogenaudio.org/index.php/topic,126205.0.html for you lossless audio format of choice.
I also want to be able to play the rip, with visible track titles, so I want to choose a method
that's widely supported by players -- my car player for example. (I chose mp4 with chapters because
that's what I know and flac-in-mp4 can be played by any video player.) I came to ffmpeg-user to
learn of a better way, a way that can be played by any multimedia player.
3) Let the ripper simultaneously generate a CUE-sheet. This is the recommended way to tag the
archived audio. Chapters are for video-files and the MP4-container is not meant for audio only.
4) I can't remember if Exact Audio Copy was capable of directly tagging the resulting single
audio-file with the CUE-sheet, because it's been quite some years since I last used the ripper, but
otherwise I'd use Mp3Tag (https://www.mp3tag.de/en/). With it you can add the CUE-sheet afterwards,
or even cover-art and all sorts of tags if you want.
If you only have those 7 WAV-files, then you could use FFmpeg for concatenating and compressing
(except for TAK), but the tagging I would leave to Mp3Tag.

I doubt that my car player, for example, will play any of those.
