摘　　要：基于音频指纹原理设计并实现一套广播电台自动化监测系统,通过对多源异构的广播音频进行统一的数字化接入与标准化格式转换,利用频谱峰值定位、能量子带映射等算法提取音频指纹特征,并采用倒排索引结构实现音频指纹的高速检索与比对。An automated broadcast monitoring system based on audio fingerprinting principles was designed and implemented.The system performs unified digital access and standardized format conversion on heterogeneous broadcast audio from multiple sources,extracts audio fingerprint features using algorithms such as spectral peak localization and energy sub-band mapping,and achieves highspeed audio fingerprint retrieval and comparison using an inverted index structure.
