Calculate file size from bitrate and playtime Options

[WaldoMonster]

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

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

Thanks for that tool
This calculation is right for Bytes.

Mabe the tool is wrong regarding Bytes to KBytes, MBytes, etc...
It uses a factor 1000 I thought for storage they used a factor 1024,
exept for Hard Disk's because it looks better that way

Hello Alex B,

I think we typed it the same time

Yeah, and that tool indeed shows incorrect KB, MB and GB values.

Also, the real 128 kbps 2min 30s files I have are almost exactly 2.3 MB. (I don't have 64 kbps files.)
