inAudible VS audible-cli

You can use software like Libation, AAX Audio Converter or inAudible to decrypt Audible books.

Libation author here. Libation reads directly from your audible account and downloads/decrypts in one step. No aax, just straight to m4b. There's also a setting to convert to mp3 instead. It cannot take existing aax files and do this. inAudible can target aax files directly but it's getting a bit long in the tooth so it's not as reliable as it used to be. I've never tried aaxtomp3.

Sorry no. You can try inAudible for that but it's rather out of date. Libation gets your encrypted files from audible and decrypts them on the fly. It's against the terms of service/conditions of use regardless, one just happens off line.

As u/JethroMcClintock said, there's inAudible (windows). It hasn't been updated in a long time so it might not work for some users. The people it does work for all seem to love it

If you have the AAX files, you can convert these to MP3s using inaudible. You do need to install the Lame codec for this to work, then it's fairly seamless. The way I look at it, you paid to buy these books, so converting them to MP3 prevents you from losing access to them in situations like this. (There is no difference between these mp3s and any other mp3 file you upload to your audio player).

Installers are here but it's unfortunately quite out of date. It was last updated in 2017 and Audible has since changed most of their catalog to a format which inAudible can no longer decrypt.

mkb79 created a powerful python app with access to the full audible api. Special shout out to him because he's single handedly done more to reverse engineer the non-public audible api than the rest of us combined.

This: https://github.com/KrumpetPirate/AAXtoMP3 + your audible key (that you can get from https://github.com/mkb79/audible-cli) is all you need.

I personally use audible-cli to download files from audible and AAXtoMP3 to decrypt them. Don't know anything about Kobo. audible-cli: https://github.com/mkb79/audible-cli AAXtoMP3: https://github.com/KrumpetPirate/AAXtoMP3

I use a combination of this for downloading https://github.com/mkb79/audible-cli

this command line program is available if you're ok with not having a GUI

One user created a plugin for my app. With these you are able to import your audible library data to Goodreads. Take a look here for more information.

For less convenient but powerful command line, there's this one, also free and open source.

It's definitely possible but I don't know of an easy way. There's a python audible api and a CLI wrapper for it. You can search this documentation page for "sample". Those are the api calls which will give you the url of the sample clip's audio file.

If you don't mind the lack of graphical interface there's also a cross platform python library with a CLI layer. It's not as intuitive to use but it's very powerful.
