Windows Media Encoder it’s a great program to stream audio over your LAN/Network or Internet.
I Have a police scanner / receiver. From the radio I have a 3,5mm minijack plug into my computers microphone.
Then I use Windows media encoder to encode/compress the audio signal and make a audio-stream.
On the client side you can use Windows Media Player to play the audio stream.
If you want to stream this out on internet , you need to activate portforwarding on your router to the IP address of you “server”-computer. You can choose by our own wich port number you want to use.
This way I can sit in my office and listen to my scanner at home! All for free! Take contact if you need help with setup. Download Windows Media Encoder from www.microsoft.com under the download section.
