A) Transform Technique : 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 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.
Discrete Wavelet Transform: A Technique for Speech ...

Abstract: This paper applies wavelet analysis to speech compression. A mother or basis wavelet is first chosen for the compression. The signal is then decomposed to a set of scaled and translated versions of the mother wavelet. The resulting wavelet coefficients that are insignificant or close to zero are truncated achieving signal compression.

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

A. Wavelet Transform . The discrete wavelet transform (DWT) is a highly flexible family of signal representations that may be matched to a given signal and its well applicable to the task of audio data compression [4]. One dimensional discrete wavelet transform 1-D DWT and D 1-IDWT modules can be implemented by filter

information in an audio signal is perceptual irrelevant, most lossy compression algorithms use transforms such as the Modified Discrete Cosine Transform (MDCT) to convert time domain sampled waveforms into a frequency domain. Once transformed into the frequency domain, frequencies component can be digitally allocated according
