Multi-room Pi audio
Get your Raspberry Pis in sync, audibly throughout your home.
Multi-room audio systems can cost a pretty penny, but who needs to buy an expensive set of wireless speakers when you can use some Raspberry Pis and any 3.5mm wired speakers to achieve the same effect? We’ll use our Pi 4s and speakers/receivers (with 3.5mm audio inputs) to play music from a streaming service perfectly in sync via Bluetooth from our phone, tablet or computer. We’ll show you how to do this with a single speaker and Raspberry Pi and then replicate it in other rooms. This is an excellent project for repurposing old receivers. If you have a non-Bluetooth receiver with a 3.5mm jack input, you can connect your speakers to your receiver and your receiver to your Raspberry Pi.
