I would like to run a command to be executed in background monitoring the output to the speaker and record what’s played.
I used the following command:
parec -d alsa_output.pci-0000_00_1b.0.analog-stereo.monitor | sox -t raw -b 16 -e signed -c 2 -r 44100 - test.ogg silence 1 0.1 3% 1 3.0 3%
It works, but it is running in forground listening to the device… I tried use
tmux but it didn’t record the sound…. any solution?
I prefer a command line as a startup service to listen to the speaker output as long as it’s not stopped, however later I found
pulseaudio as a required service isn’t run as a wide-system service and making it wide-system causes some problems in sound system….
Now this question isn’t my priority but if one knows a solution can offer.
