I have multiple speaker-settings in my room and in my bathroom, and now i just have them connected to a digital mixer, that can handle monitor outputs, but as soon as the pandemic thing is nearly over i want to hire it out again, and listen to music at the same time! I have a fully processed stereo mix comming in to the mixer, but i need some arduino hardware to control its outputs!
What i need:
a piece of hardware (some sort of chip) that let arduino controll audio volume for different speakers.
2 analog signals split up to 16 analog outputs, controlled with arduino (via internet, but i can code).
What hardware to use? In worst case scenario, i glue servo's to pots, because its literately recalling of presaved presets, but there must be a cleaner way, to dampen the audiosignal, without signal loss ofcourse. If the audio dampens if another speakers comes up, its fine. I'll need to adjust volume after an speakerchange anyways.
I dont know if dampening is the correct opposite of amplify, but you are all smart humans so you'll figure it out!
After a bit more searching i came across this:
Would this work by any chance? I was looking at example 4. I dont fully understand what the disadvantages would be, could anyone explain?
