How can I capture the audio output with GStreamer?

Using the following command: gst-launch-1.0 -v alsasrc ! wavenc ! filesink location="output.wav" I can record the microphone, but how can I record/capture just the audio output? audio  audio-recording  gstreamer share improve this question edited Sep 5 '15 at 17:29 JakeGould 18.4k 5 52 66 asked  Sep 5 '15 at 17:25 Michael 108 2

If you're looking to capture the output of your soundcard, you'll have to use pulsesrc and set the device property to your soundcard's analog-stereo monitor source. Have a look here. Here the relevant source would be alsa_output.pci-0000_80_01.0.analog-stereo.monitorand you'd change your pipeline's input to pulsesrc device = "alsa_output.pci-0000_80_01.0.analog-stereo.monitor"
