Pick up present for audience (4)
I believe the answer is:
hear
'pick up' is the definition.
(hearing is a kind of picking up)
'present for audience' is the wordplay.
'present' becomes 'here' ('here' can be similar in meaning to 'present').
'for audience' indicates a 'sounds like' (homophone) clue.
'here' sounds like 'HEAR'.
(Other definitions for hear that I've seen before include "Try (in court)" , "Catch" , "Perceive sound" , "Discover aurally" , "Get wind of" .)
