摘　　要：随着广播电视数字化技术的迅猛发展,音频编码技术已在广电领域得到广泛应用。介绍了音频编码的分类、原理及标准;针对广播音频信号数字化之后,面临的存储和传输等一系列问题,提出了需要对数字音频语音信号进行编码压缩以便于传输;同时还以该电台为实例对播出音频信号的传输改造进行了简要介绍,说明了音频压缩技术在数字化传输中的重要作用,展示了改造后的传输模式及其稳定可靠和安全性好的播出质量。With the rapid development of radio and television digital technology, the audio coding technology has been widely used in the field of radio and television broadcasting. The classification, principle and standard of audio coding are introduced. Aiming at a series of issues such as storage and transport after the digitization of broadcast audio signal, the digital audio signal should be encoded and compressed in order to facilitate transmission. At the same time, by taking Hebei people＇s broadcasting station as an example, this paper introduces briefly the modification of audio signal transmission, illustrates the important role of audio compression technique in digital transmission, and demonstrates the modified transmission mode and its stable, reliable and good secure broadcast quality.
