Organ filmed in hearing range (7)
I believe the answer is:
earshot
'hearing range' is the definition.
(I've seen this before)
'organ filmed' is the wordplay.
'organ' becomes 'ear' (the ear is an organ).
'filmed' becomes 'shot' ('shoot' can be a synonym of 'film').
'ear'+'shot'='EARSHOT'
'in' acts as a link.
(Other definitions for earshot that I've seen before include "Within which we hear" , "Distance within which a sound can be heard" , "To share (anag)" , "Hearing distance" , "Range of audibility" .)
