I'm trying to find a solution to return the current system audio stream in Xamarin.Forms (for iOS and Android).
As example: There is a new feature from Shazam since iOS14 where you can not record the microphone input but the system audio input, like a running Spotify song.
I just want that as a stream to filter it through Fast Fourier Transform and send it to a microcontroller for some sound reactive LED effects.
Could not find an extension or Nuget package yet, do you know any or maybe some working solution ?
Best regards nflug
