AUDIO COMPRESSION USING WAVELET TECHNIQUES
https://iosrjournals.org/iosr-jece/papers/Vol.%2010%20Issue%202/Version-3/H010234144.pdf
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
