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.

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.

space. Wavelet transform provides a time-frequency representation of the signal. In wavelet transform, the signal is decomposed into set of basic functions also known as WAVELETS. Wavelets with large number of vanishing moments are useful for this audio compression method, because if a wavelet with a large number of

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
