Need to record all sounds from sound card.


Need to record all sounds from sound card. So that mic+output was written to file. Is it possible? Cant find any examples, found just ones that allow to write mic.

Wasapi Loopback recording, mixed together with recording from microphone is the solution to this

this is called loopback recording and is possible with WASAPI (so you can't use it in Windows XP)

// can't set WaveFormat as WASAPI doesn't support SRC
waveIn = new WasapiLoopbackCapture();
from demo?.. But it records just output, no mic sound (

yes you must also record any microphones you want and mix after. It is unfortunately that WASAPI does not provide built in SRC, so you have to do it yourself.

Check out this thread for a WasapiLoopbackCapture class that takes the output from your soundcard and turns it into a wavein device you can record or whatever...
