A system and method (
) of altering the audio portion of a live television broadcast signal substantially in real time. The system is used to enhance the effects of live video insertion systems. The broadcast signal is received and separated into a pattern recognition unit (
) in order to recognize predetermined events. The broadcast audio is then altered based on the occurrence of said events. Alterations (
) include modifications to attributes such as volume, tone, pitch, synchronization, echo, reverberation, and frequency profile. Once altered, the audio is re-synchronized (
) with the video channel which has undergone its own modification.
