C & Fmod Ex - real-time PCM array / buffer playback

Question

I use an array to process the radio signal and receive the raw PCM sound. I am desperately trying to play this sound with Fmod Ex.

Basically, could I create a thread that matches my circular buffer, which I could get in a thread-safe way? Any basic information on which methods to use would be greatly appreciated.

If not, can any other Windows 7 API do the trick and how? (ASIO, Wasapi ...)

thanks ° - °
