2.2 Audio compression The idea of audio compression is to encode audio data to take up less storage space and less bandwidth for transmission. To meet this goal different methods for compression have been designed. Just like every other digital data compression, it is possible to classify them into two categories: lossless compression and lossy

integer wavelet transforms and an integer version of the wavelet packet transform. The lossless compression discussed here involves 1-D data. these algorithms directly generalize to 2-D data (e.g., images) [1]. Applications for lossless compression include compression of experimental data and compression of financial time series (for
AUDIO COMPRESSION USING WAVELET TECHNIQUES

Wavelet compression is a form of data compression well suited for audio compression, video compression,image compression. Wavelet compression methods are adequate for representing transients. Such as percussion sounds in audio, high-frequency components in 2-D images. This means transient elements of data

Digital audio compression allows the efficient storage and transmission of audio data [1]. One of the techniques that used in audio compression is wavelet transform, Wavelet compression is a form of predictive compression where the amount of noise in the data set can be estimated relative to the predictive function [2]. Wavelet coding

Implementation of Audio Compression using Wavelet
http://ceur-ws.org/Vol-1755/104-107.pdf
Although, lossless compression would keep all the information of the original signal unaltered, it has the limitation of compression ratio of about 3:1 while with lossy compression algorithms, the compression ratio can be as high as 12:1 or higher [Spector 1989]. Audio compression is very much employed in this computer age ways[Zhao and Shen 2010].

You should follow lossless compression technique as lossy audio compression results in data loss. Image and video can be compressed in a similar way. Steps to run the program Run AudioCompresssion.m file. You will get a window as shown in Fig. 1. Select audio file and then press Compress Audio button. You will get output windows as shown in Fig. 5.
