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 :
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

The different types of wavelet families are like Daubechies, haar, symmlet etc. Figure 1: Different wavelet families AUDIO 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.

Audio Compression Using Biorthogonal Wavelet Transform Wafaa S. Ahmed . Abstract- The idea of audio compression is to encode audio data to take up less storage space and less bandwidth for transmission.. An effective wavelet-based audio compression algorithm is presented to provide highly efficient signal compression mechanism withacceptable human hearing …
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

Audio Compression via Discrete Wavelet Transform - …
https://github.com/nicholaskl97/wavelets
The paper (stored in this repository as a PDF) reviews the discrete wavelet transform (DWT) and explains this code. The code is designed to compute Daubechies wavelet coefficients of arbitrary order, apply a DWT to an audio signal, apply truncated wavelet approximation to compress the signal with minimal losses, and decompress/transform to recover an audio signal.

Audio Compression using Wavelets in MATLAB Audio frequencies range from 20Hz to 20kHz but these frequencies are not heard in the same way. Frequencies below 20Hz and above 20kHz are very difficult to hear, while those not much more than 20Hz, or not much less than 20kHz, cannot be heard by most people.
