摘要：This paper shows the comparison of various lossless compression techniques. This research only concerns on audio the WAV 2 channel audio format. If an audio is said to be stereo, it means it has 2 channels (left channel and right channel). The code prefix to be generated becomes more and may appear more diverse. In this paper gives little change in the rule model for the allocation of bits to the prefix code generated. It gives different conclusions on the size and time ratios, toward existing research. The result of compression can accelerate transmission of information from one individual to another. Compression requires a technique which can be strategy against the pack of data. Information that can be compressed not only text but it can be Audio, pictures and video information. Furthermore, lossless compression is the most approach which is frequently used in data compression. Lossless compressions consist of some algorithm, such as Huffman, Shannon-Fano, Lempel Ziv Welch and run-length encoding. Each algorithm can play out another pressure. Finally, this paper generates the conclusion about the comparison of performance in Huffman and Shannon-Fano based on discussion of the result. The conclusions are difference result of compression-decompression speed and compression factor and ratio both of this algorithm.
