Is it possible to get another audio format?

Right now the tool just downloads mp3s. Is there a way to download any other format from source like acc or ogg?

audio transcoding is well out of scope for this tool

I think you're looking for ffmpeg

ffmpeg -i filename.mp3 newfilename.ogg

What I meant is if the original source its always an mp3. The tools is great and I don't think it needs trascoding. I just wondered if there are more formats in the original source stream instead of converting after downloading. Thanks for your answer.

Oh, I see what you mean: can you force the server to give you back a different file. I have no idea, but I sorta doubt it. This is a reverse engineering effort, so you're welcome to take a look at the information coming out of kobo and see if you can tweak parameters to get other audio formats. I probably won't spend time looking into this, but PRs are welcome.
