II. Wavelet Compression 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

Discrete wavelet transform is used for the audio signal compression. Wavelet transform is very suitable for audio compression. DWT uses multiresolution technique to analyze different frequencies. B) Quantization and coding of transform coefficients :
Implementation of Audio Compression using Wavelet
http://ceur-ws.org/Vol-1755/104-107.pdf
Audio compression was implemented using wavelet. The performance of the wavelet was excellent with „perfo‟=68.06%, „perf12‟=99.9929%, and „perfl‟=99.9915%. This shows The reconstruction was good as well since the error is negligible. Audio compression is used for transmission and storage. The

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

Abstract— Audio Compression is a type of data compression designed to minimize the need for the transmission bandwidth of digital audio streams and the size of the audio. An effective Discrete Wavelet Transform (DWT) is used at various scales for the decomposition of the original signal into wavelet coefficients. To

Abstract: Speech compression is the technology of converting human speech into an efficient encoded representation that can be decoded to produce a close approximation of the original signal. In this paper, we propose a new algorithm which compresses speech signals using a wavelet compression technique.
