摘要

音频数据的数字化表示具有抗干扰性强、稳定性好等优点。研究了小波变换在音频信息压缩中的应用。开发的软件模型可以找出不同因素对压缩比的影响。根据不同的参数，初始音频文件被压缩2-4次。因此，恢复的文件变形小于10%

Digital Audio Information Compression Using Wavelets

The digital representation of audio data offers many advantages: high noise-immunity, stability and etc. The application of wavelet transform for audio information compression was investigated in the present research work. The developed software model allowed to find out the influence of different factors for the compression ratio. The initial audio file is compressed in 2-4 times depending on different parameters. Thus the restored file is deformed less than on 10 %
