Method and system for reduction of quantization-induced block-discontinuities and general purpose audio codec

摘要

Enabling low-latency reduction of quantization-induced block-discontinuities of continuous data formatted into a plurality of data blocks having boundaries typically includes forming an overlapping input data block by prepending a fraction of a previous input data block to a current input data block, identifying regions near the boundary of each overlapping input data block, and excluding regions near the boundary of each overlapping input data block and reconstructing an initial output data block from the remaining data of such overlapping input data block. The continuous data may include audio data and/or time-domain data. The low-latency reduction of quantization-induced block-discontinuities of continuous data may be applied to at least one of a coder and decoder.
