基于BP网络的音频数据压缩方案

Audio Data Compression Scheme Based on BP Neural Network

介绍了BP神经网络的基本原理,并通过构造特殊的映射关系、精心设计的BP神经网络获得一套基于神经网络的高效无损音频数据压缩方案。通过试验证明该方案行之有效,并且压缩比为7∶1。

In this article, the basic theories of BP neural networks are introduced. A high efficient lossless audio data compression scheme based on neural network is obtained through the structure specific mapping and carefully designed neural network. The experiments show the scheme is efficient and the compression ratio is 7： 1.
