Well you finally got here !
Welcome to Stream320.dyndns.org the home of stereo
online radio.
This is an experimental service designed for testing and
trialing Internet Radio technologies. Yep it is a
sandbox but one that can be used for building completed
solutions.
The streaming technology is based upon the use of a
Raspberry Pi 2, 3 or 4 as the analogue stream encoder
using an Audio Injector Zero sound card. The
stream encoder being used is Darkice currently running
on a Raspberry Pi 2.
The encoded audio is fed as 320Kps MP3 encoded audio
stream to another Raspberry Pi 3 computer that uses
Icecast as the stream server.
DYNDNS is used to provide DNS hosting.
The network connection to the Internet is a 100/20Mbps
Fibre to the Premise service. So the available uplink
bandwidth to the internet is 20Mbps. With an
uplink bandwidth of 20Mbps the total mnumber of
concurrent streams would be around 62, however it is
doubtful that an ISP supplied router would have the
switching bandwidth to sustain this throughput.
A more realistic throughput might be in the order of 20
to 30 concurrent streams. So far we have not
managed to get anywhere near that..... more like 4 to 5
concurrent streams !
