Mp3 the theory behind mp3'tech mp3tech. Limit to how much you can compress data without losing any information. This means that when the compressed data is decompressed the bitstream will be identical to the original bitstream. This type of data compression is calledlossless. This limit, the entropy rate, depends on the probabilities of certain bit sequences in the data. Mp3 encoding and file format herong yang. A mp3 header has the following structure the original mp3 file format does not allow any places to store information about the mp3 file. So a new standard called id3v1 was developed in 1996.
