I am trying to get a few speakers synced up for a party, and I am flying around the internet for the best way to do it. Balena Sound seems like a good option, but I have a few questions before I buy myself another Raspberry Pi (I only have one at the moment).
Can you let me know if everything below is correct?
- A Raspberry Pi 4 is the best choice for the “master”. The “master” can also connect to a speaker.
- A Raspberry Pi 3 is a good choice for additional speakers, and can output using the onboard aux jack.
- A Raspberry Pi 4 and a Raspberry Pi 3 is all that is needed to connect two speakers (Not including power cases, sd cards, etc.)
- Balena Sound can only export from the Pi to the speaker via wire not over Bluetooth
Additionally, if speaker one were to be wired, and speaker two were to be connected via Bluetooth (See diagram), is there a way to correct the lag that is sure to occur (by delaying the wired one)?
Let me know if something is unclear.
