Audio Compression Method Based on Slantlet Transform

Abstract

The development of internet and multimedia technologies that grow rapidly, resulting in amount of information managed by computer is necessary. Audio is the most important medium be transmitted and for successfully transmission, there is a need for compression.A proposed Audio compression method based on Slantlet transform is a lossy audio compression. It exploits the high similarity between the channels of stereo audio Wave file, using Slantlet transform for transformation and Arithmetic coding in coding step. The experimental results show that compression ratio ranges (12-24) and PSNR results ranges (51 - 58 dB), encoding and decoding time improved (12 -14) times by using programmed Adaptive Arithmetic coding.
