I want to create my own project of addressable Leds usage (also led stage lights using dmx512), and I find a problem with every code and project I have encountered.
Basically almost everyone of the few projects I have found on this topic uses a sound sensor to capture the sound, but I find it quite annoying, I dont wan't the leds to be disturbed by the sound in the room being captured through a microphone, I wonder if I could get the audio signal from the pc or smartphone, trough jack , bluetooth, rca or anything else but a microphone really.
That way I couldwork with frecuencies and that stuff based only on what's being played by the media player (spotify in this case).
Is anything of this possible? If so, how? If someone were able to link me to some post regarding the audio matter in arduino I would be extremely grateful.
(P.S: Sorry if I misspelled something, I'm not english and thank you in advance)
