Bring up level for the audience (5)
I believe the answer is:
raise
'bring up' is the definition.
(raising is a kind of bringing up)
'level for the audience' is the wordplay.
'level' becomes 'raze' ('raze' can be a synonym of 'level').
'for the audience' indicates a 'sounds like' (homophone) clue.
'raze' sounds like 'RAISE'.
(Other definitions for raise that I've seen before include "better?" , "Lift up, bring up" , "Wage increase" , "What a poker player might do" , "Care for during childhood" .)
