mesh audio

Using Arduino Project Guidance

hi there i was wondering if it is possible to create a mesh based network from ether bluetooth or with to creat a mesh audio system

if possible

must be able to
add or remove a node with no iteruptions
small
light waght
relitivaly long range

would like
on the base station have some from of disply that is able to show the voltage (battery leval) and signal strength of each node
esaly expandalble

idea
basicaly i have 1 main unit (base station) that will transmit the audio to the nodes each node will act like a recever and a transmitter but i i can add new nodes at any time or remove a node at any time but with no interutions to the bradcast hens the idea of a mesh desinged network

if you dont know what a mesh network is i would recomend haveing a look as it may give you a batter idea of what i am whanting

i do know there are alredy sulutions out there for this but they are ether too exspensive, too large, ned custom batterys, or not allow esay deploy of a new node

I don't think an Arduino would have the performance necessary for a project like that. Laptops and WiFi spring to mind.

robin2 would it be possible if i did say a starndered config were all the node conect to the base station and not each other

Most Arduinos do not have:

A. WiFi or Bluetooth for communication or mesh networking
B. A DAC for audio output or DMA hardware peripherals like I²S or SPI for an external DAC
C. Enough processing power for decoding real-time audio
D. Enough processing power for streaming audio to other nodes while receiving and driving a DAC
E. Enough RAM for buffering audio

You could use something like a Raspberry Pi Zero W with an external DAC.

For all the reasons listed by @PieterP I don't think so.

If you try the TMRh20 PCM library you will quickly appreciate the limitations of an Arduino for audio
