Some audio outputs provide Windows with a reference stream directly, via a KSNODETYPE_AUDIO_LOOPBACK streaming pin.

To this end, it is, as much as possible, an accurate representation of what is coming out of the speaker. The primary purpose of the loopback tap is to provide a reference stream for applications that want to do acoustic echo cancelation. What I do know (not sure if that is the cause) is that calling mEndpointVolume->QueryHardwareSupport(&dwMask) gives dwMask=2 on the computer that works as I want ( ENDPOINT_HARDWARE_SUPPORT_MUTE The audio endpoint device supports a hardware mute control.)īUT gives dwMask=7 which is combination of all three below on the computer where it does not work as I want.ĮNDPOINT_HARDWARE_SUPPORT_VOLUME The audio endpoint device supports a hardware volume control.ĮNDPOINT_HARDWARE_SUPPORT_MUTE The audio endpoint device supports a hardware mute control.ĮNDPOINT_HARDWARE_SUPPORT_METER The audio endpoint device supports a hardware peak meter.

I.E to capture all computer sounds using wasapi loopback but that nothing will be heard on PC speakers and that when user change the Master volume that this will have no effect on the wasapi capturing

HOW TO AUDIO LOOPBACK HOW TO

I need advice how to make what i want to work on all computers. Also changing the master volume change as well the volume of the sounds wasapi captures. Problem: But on another computer (asus) Setting master volume to 0 using SetMasterVolumeLevelScalar does change the volume of the sounds wasapi captures. Sounds AND PC speakers do not make any sounds.Īlso, seems that changing the master volume does not change the volume of what is captured by wasapi (only changing the sounds from the application the make the sounds - for example Media Player, change the volume of the sounds wasapi capture) - as i want.Įverything good - this is what i want (I want that nothing will be heard on the PC speakers and I want that changing the master volume (the volume of the speakers) will have not effect on the volume of the sounds wasapi captures). Seems that it should make wasapi playback to not work as i want (i.e to capture silent only since I set the master volume to 0 which is not what i want), BUT this does not happen. So I use: mEndpointVolume->SetMasterVolumeLevelScalar((float)0, NULL) Problem is that I want it to work while the computer speakers will not produce any sound.

Generally the Microsoft drivers for sound cards that ship with Windows don't have this option. The drivers can also affect whether you have a stereo mix option or not. Please note: Only certain sound cards have the stereo mix option not all of them have it.

Now you can capture audio from any program in Windows 7/Vista.

Find the 'Wave Out mix' ('Stereo Mix', 'Record What you hear') item, right click on it and select Enable.

Right click on the background of the tab and select Show Disabled Devices.

Go to the Control panel and double click the 'Sound'.

How to enable the 'Wave Out Mix' ('Stereo Mix', 'Record what you hear') in Windows 7/Vista

Your computer is now set to record the output of the sound card as the input.

Please Note:Unless you wish to record ALL sounds your computer makes, including the startup and shutdown tones then may want to change the Windows sounds to 'off'.

The stereo mix is the output of the soundcard.

Go to Sound and Audio Devices in the Windows Control Panel.

The sound card/device must have both recording and playback capability for this to work. This was written for XP, but will also work for Win 2000 and Win 98. A virtualised server may be able to do it. Requirements: This will not work with a hosted server. Setting your Sound Card as a loopback device
