It's seen and quoted audibly (7)
I believe the answer is:
sighted
'it's seen' is the definition.
(I've seen this before)
'quoted audibly' is the wordplay.
'quoted' becomes 'cited' ('cite' can be a synonym of 'quote').
'audibly' shows a homophone (sound like).
'cited' is a homophone of 'SIGHTED'.
'and' acts as a link.
(Other definitions for sighted that I've seen before include "Saw, observed" , "Seen" , "Viewers are" , "Saw; able to see" , "Espied" .)
