Is this calculation right?
I hope I didn't fucked up with switching bits and bytes wink.gif

Thanks for the help,

Willem


CODE
Bitrate 64 kbps
Playtime 5 min

64 kbps = 64000 bps

5 min = 5 x 60 = 300 sec

            64000
64000 bps = ----- bytes/sec
              8

64000 * 300                    2400000
----------- = 2400000 bytes = ----------- = 2.29 MB
     8                        1024 * 1024

It's correct.

Normally and usually a kilobit = 1,000 bits (e.g. when data transfers speeds are showed), but a kilobyte = 1,024 bytes (e.g. when file sizes are showed).

Only HD manufacturers have a bit different math. They think that 1 GB = 1,000,000,000 bytes and so on. I guess a bigger GB amount looks better. tongue.gif
