'consider carefully from an audiobook' is the definition.
I don't know anything about this answer so I can't judge whether this works.

'passage i'll' is the wordplay.
'passage' becomes 'aisle' (aisle is a kind of passage).
'i'll' becomes 'way' (I can't justify this - if you can you should believe this answer much more).
'aisle'+'way'='AISLEWAY'
