Note:

Please be careful with the audible activation-bytes command. Each time you run it, it will make an request to the Audible server to fetch the activation blob and extract the activation_byte. So make sure to run audible activation-bytes --save first. With the --save/-s flag the `activation_ bytes will be stored to auth file and reload it instead of requesting the Audible server.

Your download command can be shorten to audible download -t "SEARCH FOR TITLE 1" --aax. If you leave out -o option the current working dir is chosen. If you only download one file, you can leave out the -j option (there is only 1 job). If you leave out -q option, the best quality is chosen (and this is high)!

i fixed the --save problem and i chose high because it was in the middle and best can take up a lot of space.
