Abstract
This invention relates to a file compression method of digital sound signals, which mainly uses a harmonic structure quad tree (HSQT) to rearrange the frequency parameters in each sound frame and apply the algorithm of concurrent encoding in hierarchical trees (CEIHT) to increase and simplify the management and calculation speed, match arithmetic coding for parameters of CEIHT masking symbol, use the appearance probability record of mask to decide the stored bit numbers, where the appearance probability is inversely proportional to the necessary stored bit numbers. Using increasing the appearance probability of mask to greatly deduce the stored bit number, the overall compression type can compress a sound signal compression file with high compression ratio in a simple management process.
