Let X be the event where a particular song is played in the background.<\/p>\n
P(X = “?? – ???”)
= 1\/4
= 1 – P(X = “JS – ???”) – P(X = “?? – ????”) – P(X = “?? – ?????”)<\/p>\n
All events are statistically independent and mutually exclusive, ie, getting a particular song now will not effect the song being played on the next visit, and there's no possibility of getting more than 1 song playing at one single time.<\/p>\n
P(X2 = “?? – ?????” | X1 = “JS – ???”) = 1\/4.<\/p>\n
Hmm…. oh well… correct or not, I dunno! I don't really like statistics…<\/p>\n
Nevermind. I reduced the song quality to 64kbps, meaning 64 intervals as filter? Or what? Dunno… .<\/p>\n
??? is 4 minutes, 7 seconds long. So, at 64kbps, it will be 64 000 * [(4 * 60) + 7] = 15 808 000 bits.
8 bit = 1 byte => 15 808 000 \/ 8 = 1 976 000 bytes.
The actual file size is 1 982 115 bytes. Difference is 1 982 115 – 1 976 000 = 6 115 bytes.
UTF-8 uses 1 to 4 bytes per character, so assuming 4 bytes per character, I will have
6115\/ 4 = 1258 characters.<\/p>\n
In that file?! 1258?! Opps something wrong somewhere… wahaha<\/p>\n
Never mind… just crapp… but the conversion is already quite zhun… lol…<\/p>\n
Oh well… <\/p>\n","protected":false},"excerpt":{"rendered":"
