How to create an audio switch?

Hi All,
My requirement is, to create an Audio Switch. The switch will have various Audio inputs(3.5mm/Stereo cable), and one Output(3.5mm). When I request for one of the Audio sources(which are inputs), I should get only that Audio source. Is it possible to create something like this via Arduino Uno? Please let me know where I need to start and what all the components I would need? I am new to Ardiuno with very less Electronics knowledge(But I do have programmatical knowledge), so please help me where I need to start and which modules I need to have look at. Any help is greatly appreciated.

Yes, I have made several. video and audio.
