Thanks Mark,, i will use WasapiCapture /AsioOut the ones you recomend, by the way you mentioned about rolling over , i am afraid that it might lose some byte. I think to rollover to a new WAV i have to call Stop to call BenginRecord again to save the current one and create a new WAV file? If i know is wrong could you show me more in detail if some line of sample codes or guides.
Many Thanks to you
