Echo memory featuring dwelling (4)
I believe the answer is:
home
'dwelling' is the definition.
('home' can be a synonym of 'dwelling')
'echo memory featuring' is the wordplay.
'featuring' indicates a hidden word.
'HOME' is hidden within 'echo memory'.
(Other definitions for home that I've seen before include "Residence" , "Domicile" , "It's where the heart is, it's said" , "Living place" , "Habitual abode" .)
