Is your feature request related to a problem? Please describe.
No.

Describe the solution you'd like
Is there a difference between the files from standard Audible books and Spatial Audio ones? If so, can they be fetched by Libation?

Yes. The only caveat is: make sure this item is disabled -- Settings, Audio File Options tab, Downsample stereo to mono. It will still download, but will sound wrong.

Yes, but please don't ask me what they are.

If so, can they be fetched by Libation?

Nope. Libation only downloads the standard stereo (actually duplicated mono) AAC audio files. In theory it could, but I don't own a device that supports Dolby Atmos so I can't reverse engineer what we'd need to do to get those files.

@Mbucari Why wouldn't Libation be able to support anything, as long as it's just a file wrapped in encryption?

It probably could, but I don't know how to request a Dolby Atmos file. We can get High and Low quality, but those are your standard stereo audio.

I have a compatible device and could supply a pcap if you know of a way to disable certificate pinning for Audible Android.

Seems my phone also supports it. Let me know if there's anything I can do to help you.

The spatial audio files have a different encryption than aax or aaxc files. I was able to download these files. But I can’t get any further with the decryption part! Here you can read a little bit more.
