What is a .axa file?

A .axa file is an annodex audio. Its registered MIME type is audio/annodex, which places it in the audio family of formats.

Technically it is a specialised form of application/annodex (the .anx format), so tools that understand that format can often read at least part of it.

AXA is a binary format: the contents are not readable text, so opening it in a text editor shows scrambled characters.

Files of this type usually begin with the bytes 4F 67 67 53. That signature is how programs recognise the format even when the extension is wrong or missing.
