pipewire-capture-window

Send audio from a window to a virtual capture device

Usage

1. Make a virtual input to loop captured audio.

Example pipewire.conf:

# ...
context.objects = [
    {   factory = adapter
        args = {
            factory.name     = support.null-audio-sink
            node.name        = "capture"
            node.description = "Virtual Capture"
            media.class      = "Audio/Source/Virtual"
            audio.position   = "FL,FR"
        }
    }
    # ...
]

2. Edit capture-window and change DEST="capture" to the node.name.

3. Run script, select window, and direct whatever recording program to use the loop device.
