What is difference between Byte to Byte comparison and Sound Content comparison?
Byte to Byte comparision, comparision that made bit by bit, two files identical if all bits in them are identical. This method of comparision useless in music duplicates finding, because, usually, duplicates have different sample rate, different bit rate or information tags, ie. different characteristics (which incompatible with byte to byte comparision). Sound content comparision (which uses Similarity) is different, first sound decoded to raw sound waves and after used in different mathematical calculations to get unique sound estimation (hash). What estimation used in comparison with other sound estimations. This method of comparision give much better results than simple byte to byte comparision or tag comparision.
