Recording room (6)
I believe the answer is:
studio
'recording room' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for studio that I've seen before include "Workroom of an artist or photographer" , "MGM, for example" , "Unpleasant vapour" , "Workplace for artist, photographer etc" , "Atelier, say?" .)
