I'm trying to record the output of my speakers, but when I do this, it also records from the microphone. I'd like to only record the non-microphone devices.
$ (AUDIODEV=hw:0,0; rec test.mp3) $ rec -d hw:0,0 test.mp3
I've also tried ffmpeg:
$ ffmpeg -f alsa -i hw:CARD=PCH,DEV=0 test.mp3 $ ffmpeg -f alsa -i front:CARD=PCH,DEV=0 test.mp3 $ ffmpeg -f alsa -i surround40:CARD=PCH,DEV=0 test.mp3
I've seen elaborate things such as:
$ parec -v -d analog-output-speaker | sox -t raw -e signed-integer b 16 -r 44100 -c 2 test.mp3
Proposed online, but this still records the mic, and comes with obsolete sox options.
How can I record only non-mic input in ubuntu 14.04+ ?
