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.

Audio Compression Using Wavelet Transform
http://www.iosrjen.org/Papers/Conf.19014-2019/Volume-4/7.%2032-36.pdf
The discrete wavelet transform performs very well in the compression of audio signals. For real time audio processing however, its performance is not as good. Therefore for real time audio coding it is recommended to use a wavelet with a small number of vanishing moments at level 5decomposition or less. References [1].

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

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
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
