How do I calculate bandwidth for a stream?

but if I have a shoutcast stream that is 128kbps

does that mean one person would be using 7680kb per minute?

so, if I had a stream that was 128kbps and had 50 users for one hour, i would use 234gb?

i think i figured that out, but if I am wrong let me know

would of been like around 750kb per minute. if its in KPBS
is it bits or btyes

go question

anyone know if shoutcast is bits or bytes

I think it is bytes

Look at your MP3's on your HD

You'll see that 128kbps averages about at 1 megabyte per minute. So a 6 minute song would roughly be 6megs, give or take some. I'm guessing 750k/minute is a better esitmate though

its 128 kilobits/sec
8 bits = 1 byte

128 / 8 = 16k/sec

60 secs x 16kbytes = 960 kbytes
or almost 1megabyte/sec

if you use a more flexible codec expect:

750kb/min to 1MB/min

But more useful is:

8 listeners @ 128kbps = 1Mbps
kilobits/sec = megabits/sec

so 50 listeners = 6Mbps

and if your stream stayed that way for a month it would be 1800GB or 6Mbps
