摘　　要：改进型广播播出音频自动监控系统是通过检测音频在延时器前后的信号,精确确定垫乐时机智能设备。由于自动垫乐的实现非常依赖智能延时状态监测,后者是实现垫乐策略优化的前提和保证,为此开发了信号比对的智能算法。This system is an intelligent equipment, which is accurately ensured the timing of background music playing through checking the audio signals before and after time delayer. The implementation of automatic background music relies on the detecting of intelligent time delayer＇s status, and the latter one is the precondition and guarantee of implementing strategy optimization of background music, therefore the intelligent algorithm for signals contrasting is developted.
