Lossless audio CODEC using non-repeated dynamic block encoding

In this paper, a lossless audio codec with dynamic block coding has been proposed. In the present technique, audio signal is compressed by integrating dynamic sampled value segregation and block coding method without losing any information. Novel block encoding method is performed over the generated dynamic bit sequence of sampled values and followed by eliminating repetitions of bit patterns and entropy encoding. Compression quality is justified with considering decoded audio quality and achieved compression ratio which is compared with existing lossless audio coding benchmarks. The performance measurement of the proposed system comparing with other reference systems is shown considering some crucial qualitative parameters.
