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

Abstract— Audio Compression is a type of data compression designed to minimize the need for the transmission bandwidth of digital audio streams and the size of the audio. An effective Discrete Wavelet Transform (DWT) is used at various scales for the decomposition of the original signal into wavelet coefficients. To

Lossless compression in audio is usually performed by waveform coding techniques. These coders attempt to copy the actual shape of the analog signal, quantizing each sample using different types of quantization.

High-quality audio compression using an adaptive wavelet packet decomposition and psychoacoustic modeling. Abstract: This paper presents a technique to incorporate psychoacoustic models into an adaptive wavelet packet scheme to achieve perceptually transparent compression of high-quality (34.1 kHz) audio signals at about 45 kb/s. The filter …

advantages of Wavelet transform are to provide characteristic of multiple resolution and global decomposition that are the significant features for the audio compression applications. The best compression ratio that obtains on it is (13.4) and the PSNR is (38.66) in the sound1, when the number level is (5) and quantization step value is (30).
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
