Choosing number of listeners

26th October 2000, 17:05

Wow! thanks for your help on my previous question! I need to know how many listeners i can support. I have a DSL connection, broadcast at 24kbps, 22 kHz, mono,3kb/s. What would be a good number to set up for listeners that would minimize skipping? I have told a lot of people to listen, but i dont know what number to set to make sure all the listeners can hear. Please help!

There's a formula that will give you a good idea on the number of listeners you can support. It is:
# of listeners = .9*(upload speed)/(desired bitrate)

There is a page setup here that will do the calculation for you.

Here is an example to make sure you put in the right numbers:
ADSL: 768down/128up (It is only upload speed you are concerned about)
Bitrate: 24 kbps
# of listeners = .9 (128)/(24) = 4 listeners
Of course this is assumming that you actually get 128 kbps upload and that nothing else will be using the upload bandwidth.

This bandwidth clac still does not make snice to me. I have had about a 100 listens on a t-1 and the server was just fine.
Once Agian I come back to the question when will we get a shoutcast with multicasting support.???? Come on guys shoutcast would be so great if we could get multicast in it.

the problem is that multicasting is not fully supported, so you would be cutting out people from being able to listen to your stream

my @home provider doesn't even have Multicast support.
Sux, yes

No you would not. ANYONE can connect to a multicasted ip transmission..... just not everyone can send them.
ISP's making thier servers multicast enabled isn't that hard... but it does cost a little. Depending on how you do it.. they can buy upgrades for thier routers, or they can go the mbone route... either way its not terribly expensive and I KNOW at $20-50k a person they can AFFORD IT!

Its like I said the first time.....
ITS NOT A TUMOR!!!

oops... correction.. thats $20-$50 a person....
(hell.. would YOU pay 20K for a dial up!?>!!?)

That's strange because all of the Multicast applications I have tried never work.

Mulicast is spreading,
as for the first comment that it only take your isp to be multicast is incorrect. Every router between server and listener must be multicast enable.
So Yeah it is a bit off before we see the full internet supporting m-cast. However there are two things you have to remember.
1. Multicast has been around a lot longer than people think and it has spread across the net much more than most poeple expect.
2. a Server (shoutcast please) can be set up to support mutlicast with a roolover to unicast. Therefore someone connects in, It then tries to send out multicast, if that does not work they plug that client into a unicast.
Mediaplayer by MS can do this. I am not sure on real player but I bet it could. Here is my beef. Shoutcast is the best. (for Audio)
Why cant we see an attempt at m-cast. Even if it does not work for everyone yet, I believe in the near future it will. PLEASE GIVE US M-CAST! Imagine how many great stations would come out of the abilty to set up a server to serve 1000's of poeple.
anyway one thing I feel it is important to mention. Shoutcast is still the best. I have used, media services, and many other formats to make Radio Evolutions shows avialable. Shoutcast still works the best. And we for one, Want to Thank Shoutcast for all the great work

Well I am not in anyway saying that it shouldn't have multicast support. But this is probably one of the reasons we haven't seen added. I remember hearing way back that they were doing research into it, and that they are trying to figure out how to program for it correctly. I haven't heard much about it lately.
