I installed it yesterday and started having it chug through the Murderbot series I got in epub format. It seemed to be taking forever, but then I checked a system monitor and discovered it was using the GPU to do most of the work. So whenever my GPU-heavy screen saver kicked in, it slowed to a crawl.

At any rate, it was done this morning but then I forgot to bring the files to work, so I can't say at this point how good a job it did? It was a bit of a pain to install because it needed Python 12 and wouldn't accept Python 14 for some reason, and pyenv on my Mac is a bit of pain because it hates tkinter. Go figure. But I got it working in the end.

    A little follow-up on this. Tonight I had a look at what it generated. It produced 2 files: a .wav and a .ass. The latter apparently contains subtitles that sync to the audio. But how do you play them together?

    After searching around online, the general consensus seemed that you need to make a video file that throws it all together. For the background image I used a still of the book cover art. Then I ran an ffmpeg command that looked something like this:

    ffmpeg -loop 1 -i cover.jpg -i abogen_file.wav -vf subtitles=abogen_file.ass -shortest audio_book.mov

    It sounds pretty awesome and looks like this while it's playing!
