摘要 分析了MPEG压缩音频分析的基本原理和方法,介绍了一个MPEG压缩音频前端分析工具的设计与实现,能够方便准确地对MP3格式的音频进行分割、特征提取和归类,可用于多媒体数据库、数字化图书馆以及多媒体编辑等领域。 An MPEG audio front-end analysis tool based on auditory model and neural networks is introduced, which can also be used for MPEG audio segmentation and feature extraction in practice. The classifier can also be applied into the following fields, multimedia database, digital library or multimedia editing, etc.
