Must:
1 Nic
1 Full duplex Sound Card (enhanced, would be better)

Bind to IP:
Set this to the IP address that the device has. 

Port:
Any port will do the job (1025 to 65534). Below 1025 is usually reserved ports but in many cases will do the job too.

Password:
This is the admin password the check the statistics of your IBall server.

URL:
It will create the address to which your clients will connect. The address is composed in three parts, address, port, stream name. In the latest image the client address would be 
http://192.168.1.168:8080/baraka. A more user friendly way would be to change the IP address to a name that your DNS server could point to.
ie: http://host.yourdomain.com:8080/baraka. Once all the fields are filled in the full address of your IBall server will appear in the Client connection string box below. You can test if your server is responding by double clicking in the Client connection string box. It may take up to 15 seconds for IBall to be up and responding.

Channels:
At your choice, you can set it to mono or stereo. The default is stereo.

Bit Rate:

• 24Kbit/s mono 16 or 22 Khz is a good format, low quality that can reach everyone also dial up connections, and it is comparable to AM signal quality.
• 64Kbit/s is much better quality, but dialup modems often have problems connecting to it.
• 92Kbit/s is comparable to FM radio signal quality, 55.6k but modems can't listen to it, because is too much bandwidth for dialup connections.
• 128Kbit/s is comparable to cd quality, so if you know that the people you are sending your radio to have enough bandwidth why not give them the best quality of sound?

If you need CD-quality sound, neither Vorbis nor MP3 (nor any other lossy audio codec) can provide exact reproduction.

Frequency:

Max clients:
Keep in mind that the number of client will result to bandwidth taken. ie: 100 clients * 128 Kbits = 1.28 Mbits. Make sure that you don't exceed the bandwidth that you have. We recommend not using more that 80%. In this way you'll have place for bandwidth bursts that may occur.

Volume:
This volume may not work with some sound cards.

Apply:
Apply the new settings. It may take up to 15 seconds for IBall to be up and responding.

Find yourself a good sound card

http://www.pcavtech.com/soundcards/reports/index.htm 
Don't buy the cheapest, cheap = poor sound quality + noise.

Full Duplex = Sound card can record and play back sounds at the same time. Typically sample playback and recording sample rates must be same.
Enhanced Full Duplex = record at one sampling rate, play at a different sampling rate, simultaneously.

Gain
Poor audio quality, both in terms of distortion and noise, often occurs due to improper gain handling. First, bear in mind that every amplifier has a range in which s/n ratio is optimal. This is usually not all-the-way-up! Also, remember some amplifiers sound better than others.

When connecting a mixer (or any other device) to your soundcard, there is a mixer output amp and the soundcard input amp. It is safe to assume the soundcard amp is generally the worst in the studio. So in order to obtain maximum quality, let the mixer do the work and keep the soundcard input (often termed record gain) down. Watch out, though: other cards will mute the input at zero. Anyway, keep it as low as possible and crank up the mixer output as much as soundcard can handle.
This has another advantage: the signal that flows through the cable will be louder than with low mixer out and high soundcard in. Thus, the noise from random electro-magnetic garbage that creeps into the cable will be (relatively) lower.

Generally, try to find those parts of the signal chain that are likely to pick up noise, usually long cable runs or everything inside the computer and keep the signal as loud as possible there.

Try to provide as high a level to the card's converters as it can stand, i.e. without the slightest distortion. Remember: a shiny 20bit adc fed with too weak a signal will sound like an old 8bit. We certainly don't want that type of sound.

Same rules apply to the output. Most soundcard mixers work in the digital domain. if you turn it down to 1/3 maximum level, you will again cripple your 20bit dac to 8 bits. So leave the output way up and control the volume at your monitor amplifier. You will gain considerably more detail at low level."
