A LOG-EXP Compression of Digital Audio

摘要：

We describe a LOG-EXP Compression approach to perce -ptual audio coding is presented in this paper. This algorithm is based on the lossless Compression approach and use the LOG-EXP Logarithm Algorithm to improve TTAENC and Audiopak. Its error is less than 1/256 and compression is faster than the TTAENC and Audiopak encoder. Simulation results are demonstrated for several audio signals to show the superior performance of the new method.
