The Digital Chalkies and I tried broadcasting on the Sanbox Channels. It worked pretty well!

Things that worked:

We did not use Audacity at this time

Whenever you open Nicecast, you need to check your settings. Often the default settings appear even after you have reset them

Settings:

Source: Choose Audio Device: Choose your Mic.
Info: Name: Put in the name of your Broadcast
Quality:
Preset: Custom
Bitrate: 64 Kbps
Sample Rate: 44.100 Khz
Channels: Stereo
Cpu Usage/Quality: Least (up 2 notches)

Go to Window: Show Server
I used Sandbox B so the name I chose is SandBox B
Server Type is Shoutcast
Account: Blank
Password: I probably shouldn't put it here
Address: 70.84.34.202
Port 8006

Quit Nicecast and relaunch. Choose the Share tab and make sure the server is listed.

Then click Start Broadcast. Success!

It's hard to hear yourself talk, but you get used to it.

Now onto recording our sessions....
