Looking for automated audio conversion

I have a bunch of radio shows in .opus format. Each show is split into
1 hour segments so there's 3-4 files per show.

What I'm looking for is a way to scan the folders (there's one show
per folder), join the files together, then convert to mp3 or m4b. So I
end up with one file per show.

Anyone know of anything like that?

I don't know about any off-the-shelf solution but if you have just a
bit of scripting knowledge this would be really easy to do using
ffmpeg and a cron job to schedule a custom script to scan and invoke
the appropriate ffmpeg command as needed

That's beyond my abilities unfortunately. I'm savvy enough to read a
script and modify it to make it work, but clueless coming up with the
script in the first place.

maybe this will be helpful? https://trac.ffmpeg.org/wiki/Concatenate
There are some one-liners in there you could run manually for the
completed radio folders where you aren't waiting for more shows before
merging them

You can download reaper for free, drop your files in (in order) and
then make render queues to render the shows accordingly.

What does the naming scheme look like? Is it like "part1.opus",
"part2.opus", etc?

I'm an amateur programmer, bored, and feel like stitching together a
program. lol.

[Here's a repo for it.](https://github.com/remghoost/opus-stitcher)

It's a drag and drop gui. Just drag the folder onto the gui and it
should process the files inside (in alphabetical order), then name the
output `.mp3` after the folder's name. It will put the output into the
folder you dragged onto the gui.

Sorry, pyinstaller is being a ~~bitch~~ today, so you'll have to `git
clone` and whatnot. Instructions in the readme.

Written in python 3.10.9, but should be fine in other versions
(probably).

No problem.

Let me know if it works / if there's any changes you'd like.
