Is it possible to stream audio from smartphone to my arduino?

And if yes, what does it require?

Does it require programming from the smartphone side?

I know programming on the arduino. I have even worked with some RF. But i have never touched a smartphone before, so i dont know what to do to approach this task...

Of course. Not that the Arduino will be able to handle audio without being damaged, nor is it fast enough even if you pass the audio through an op-amp to offset it to all positive.
