'high-pitched sound' is the definition.
'beep' can be an answer for 'sound' (beep is a kind of sound). I'm unsure of the 'high-pitched' bit.

'live put on record' is the wordplay.
'live' becomes 'be' (synonyms).
'put on' means one lot of letters go next to another.
'record' becomes 'EP' (abbreviation for extended play record).
'be'+'ep'='BEEP'
