2dxAutoClip-AppLbHelper

Application loopback audio executable. ships with main 2dxAutoClip program

To use this helper application in standalone mode, obtain the process ID for the process tree you wish to capture or exclude from capture. You can use Task Manager or the tlist program to get this ID. Run the app with the process ID, the desired capture mode (including the process tree or excluding it), and the output WAV file.

Examples:

Capture audio from process 1234 and its children: ApplicationLoopback 1234 includetree Captured.wav

Capture audio from all process except process 1234 and its children: ApplicationLoopback 1234 excludetree Captured.wav

Note that this sample requires Windows 10 build 20348 or later.
