C# - mciSendString, any solution to get the buffer (array)? -

i'm creating reader / recorder using mci through dllimport of winmm.dll: mcisendstring see here.
works many things, recording, playing, that's pretty cool. processing on did not find proper way, method, trick buffer during recording (array)? (without saving wav file first).

any idea?

"provide code sample shows buffer want get. – jeffrson yesterday"
=> want perform fft on buffer (would single[] precision array), implemented fft this. fact have no idea direct information except save record file , process it.
=> perform "real-time" audio processing, or least figure out how set event every 4000 bytes buffer containing data (i guess there one, mci document not quite clear enough me)...

edit ii: found partial solution here (still mci): see here
, here: see here

i try put answer possible, not agree idea, that, long sources related topic answer provided in. prefer put own code , showing works.
