An audio segment insertion system is used in conjunction with a FM transmission chain and translator for unobtrusive insertion of audio segments into a translator broadcast. An encoder inserts an unobtrusive insertion signal into a primary broadcast produced by the transmission chain to correspond with a spot break in the primary broadcast. A tone decoder is connected to the translator for receiving the primary broadcast and detecting the insertion signal. A computer is connected to the tone decoder to thereby allow the tone decoder to transmit the insertion signal to the computer to signal audio segment insertion. The computer establishes an insert window time interval based on real time information during which audio segment insertion is permitted. Upon the computer receiving the insertion signal during the insert window the computer effects insertion of a selected audio segment into the translator broadcast.
