I spend most of the day with some form of multimedia burbling in the background. Streaming radio over the net is often heard around my house. The RPI4 is an extremely frugal tiny machine that consumes so few watts I leave it on permanently. This makes it an ideal machine to source the radio. This week I've had a large chunk of time to devote to this week's blog. What better time to look at, in detail, a range of internet radio software that runs on the RPI4.
