What is a good chip (IC) for audio switching to more than 2 inputs/outputs?
The plan is to have 8 inputs and 8 outputs. Only one input can be connected to an output at any time, but it also needs to be able to connect to more than one output (up to all 8) at the same time. And be able to handle other inputs being active and going to other outputs at the same time. Ie I'm listening to music in 3 rooms, and my wife is listening to different music in another at the same time. I go into another room and switch my music to the new room, without interrupting or interfering with what my wife is listening to.
The IC used in this guide seems like a good starting point, but I need something a bit more advanced. I know there's gotta be a better IC out there for doing what I want, I just don't know enough about electronics to know where to begin?
Any help would be greatly appreciated.
Wireless, wi-fi, streaming, etc. is out of the question because I have yet to see a system that 100% of the time does not have a delay between 2 or more outputs. Hence why I am running wires.
FYI I know basic electronics like what things are and I'm not afraid of soldering. And ofcourse I do plan to put my finished product up here as there is a lack of any mult-room audio projects.
