It doesn't say if it's using stereo or mono quality. You should read the
MP3-HOWTO. In the bandwidth considerations section you'll find:

"Consider this scenario. A T1 link has a capacity of approx. 1.55
Mb/Sec. If you stream your MP3's at 128K/Bps stereo, each connecting
player will use 256K/Bps, so only 6 users could connect to your MP3
server at any time without problems."

So, if you want to broadcast to 100 listeners at 24 kbps (mono), you'll
need about 24 kbps x 100 = 2.4 Mbps of bandwidth, and you must double it
if you want to broadcast at 24 kbps (stereo)
