Icecast - Feb 2005 - How much CPU horsepower?

I'm building a server. It will be using icecast and ices2. Sound quality
will
be Q=5, and I'll need to set a max bitrate. It will be running full duplex, 
with both incoming and outgoing streams, using an M-Audio Delta 44 (96 kHz 
sampling rate) sound card.

How much CPU am I going to need?

Thanks in advance for any advice.

Icecast uses trivial amounts of CPU. Don't worry about that.
The only thing that will require any substantial amount of cpu here is
ices2, for encoding things. How much cpu that will require depends on:
number of separate streams, number of channels, and sampling rate.

You can get a rough estimate of what this will require by using a
vorbis encoder such as oggenc to encode a file with the same
parameters (sample rate, channel count) as you intend your stream to
have.

For a single stream, you won't find the amount of cpu used too bad.

Hello,
One question about cpu and ram.
I'have a pentium IV with 512 Mb of Ram, running icecast2 in debian.
If I supose that i have unlimited *bandwidth,* how many streams support 
at the same time?
I want to stream ogg audio at 32 kbps.

Thanks in advanced,

Raul.
