Figure 1: Different wavelet families 2.2Audio compression using wavelet: Transform means converting time domain signal into the frequency domain. Transform coding is the type of data compression for natural data like audio signal. In this, the knowledge of the application is used to choose the information to discard, thereby lowering its bandwidth.

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

There are two reasons make audio compression is popular: 1. People's aversion of throw anything away and love them to accumulate data, not important how big a storage device one has, sooner or later it will be reached to overflow, data compression appear useful because it delays this fact. 2.
