Hi,

I want to know that what about the shoucast winamp radio server maximum user limit? I see there are very limited users like 32 or 64 on some servers. Is it about bandwidth limit? On the other hand is this radio server use a big cpu or ram? What i need to host about 1000 listeners on a radio server? I have a dedicated server that i wrote the specification below:

Core 2 Duo 2.20 GHZ
1 gb ram
1300 gb bw

Also my web site run on this server. Is it enough for me? Could you please explain this in a easy way? ( my english is not good, sorry for this)

The limitation is not on the CPU, but on the bandwidth.

But as I see your stats, I think you are not quite clear about the bandwith denomination.
To stream to 1'000 users, at 128Kbps, you will need 1'000x12.8 Ko/s.
It's a rough approximation, but you get the idea.
This mean, that for your case, you will need approximatively 12~Mo/s connectivity.

This is an "instant" bandwidth. When I see that you write

1300Gb bw

I'm more inclined to think that it's the total data transfer allowed per month.
Not the same at all.

And that's precisely why some streams have only 32 user available.
32x12.8 Ko/s= ~ 400Ko/s
Much more current and sustainable.

Check here, for example, about the prices an specialized audio stream company practice [ http://shoutcast.setnine.com/ ]
It's not a surprise the prices are so high for 128Kbp/s streams; unmetered bandwidth is what is the most costly on hosting.

Sorry i forgot to write the instant bw. It's 4 Mbps (1300GB/Throughput).

In this case for Bit Rate: 64 Kbps how many user can i host approximately? Is it 64?

the computation is simple:
bitrate/10 x number of connections = instant bandwith

so:
number of connections= instant bandwith/(bitrate/10)

4000/(64/10 )= around 625 concurrent clients

Those computation are rough.
First, it's 8 bits (and not 10) par Ko, and then, every TCP packet that fails to reach your listener needs to be resent.
Plus the metadatas, and the web site traffic, it makes a lot of variables about the maximum clients for your bandwith.

But you've got an idea...

Wooow. Thats great formula. Thanks for this. I understood it.

One more question i want to ask if possible

I am using a DSL connection. 1mps download, and 512 kbp upload limit.

I told that my server has 4mbps connection and shoutcast server is running in my server.

If i connect the shoutcast server through my DSL connection and make this radio publishing what about the user limit and radio quality?

I'm not a pro of shoutcast, but what you may want to look for, is the definition of a reflector.
I'm not sure, but I think it's something that allows you to brodcast from your pc to your server, and your server makes the multiplexing of the input to all the clients

It means somethnig like that:

    X  ---------> X <==========
Your pc       Your server      ¦
                               ¦
    ---------------------------¦
    ¦  ¦  ¦  ¦  ¦  ¦  ¦  ¦  ¦  ¦  
    x  x  x  x  x  x  x  x  x  x    <= The clients

Edit:

Thanks for your help. I am going to think about this.
