In the proposed lossless compression scheme, the main idea is to use the Approximate-Common-Factor Coding for the pre-processing of the floating-point data compression. This scheme can reduce bit rates significantly, especially when the input values in a frame are constructed by multiplication of the sequence of integer values and a floating-point constant. This scheme has been proposed for the MPEG-4 ALS (Audio Lossless Coding) core experiment and accepted as the part of the reference model.
