In the good old days, you had to modulate audio signals onto an RF carrier so they could be received and demodulated to produce something more or less audible. Nowadays things are different: audio signals are compressed and put into IP packets that are ‘streamed’, and you can access every Internet radio programme in the world by receiving, buffering and decompressing these packages. This is all very easy with the Elektor Internet Radio. State-of-the-art hardware and all open-source!
