Process radio stream real time
I want to create a program in C++ that is able to process a radio stream (audio) in real-time that is broadcasted over the internet. However, I dont know how to get this audio stream in my program. Maybe it is possible to play the audio stream in a browser and capture the audiostream from the audiocard in my program or something?

The final goal is to process the stream and recognize a specific sound that I already recorded. 

All tips are welcome.
