Sound recorded from condensor mic only comes from the left channel #228

Open djnotes opened 1 year ago

djnotes commented 1 year ago

Bug report checklist

First of all, thanks to the author of this software. It is simply the best I have found for Linux, because it shows the status of recording and has many options.

Describe the bug Not sure this is a bug. The sound of the video recorded with VokoscreenNG comes only from the left channel. I know this is because my mic records only one channel, but Vokoscreen cannot be configured to record mono so that the output video sounds from both left and right channel. I can run an FFMPEG channel mapping on the output video to handle this but I hate it. Could you please make VokoscreenNG handle this automatically?

To Reproduce Steps to reproduce the behavior:

  1. Go to 'Vokoscreen'
  2. Click on 'Mic icon'
  3. Enable check against 'your audio interface (in my case PCM2902 Audio Codec Analog Stereo)
  4. Start recording your desktop and say some audio message to your condensor mic.

Expected behavior Sound to come from both channels

Can Vokoscreen somehow handle this or is there a workaround I can use to get this done?

djnotes commented 1 year ago

As a side note, OBS has a configuration option to set recording channel to either stereo or Mono (as needed in this example) Screenshot from 2022-07-23 22-09-26

vkohaupt commented 1 year ago

Is this behavior with all players?

djnotes commented 1 year ago

Internal Vokoscreen player, ffplay, mpv, Firefox, and VLC (in the stereo mode). In VLC, when change to MONO from Audio->Stereo Mode->Mono, then sound comes from both right and left speaker (headphone). I think it would be great if Vokoscreen could be configured to record to a mono channel instead of a stereo channel. Are there currently any workarounds?

vkohaupt commented 1 year ago

I have to ask because the answer is not clear. Do all players only output audio from the left speaker? Or is VLC the only one.

djnotes commented 1 year ago

Sorry for being vague. All players including VLC output sound from the left speaker. However, in VLC you can switch to Mono from Audio->Audio Channels->Mono to hear from both speakers.

I remember I had the same issue on Mac desktop recorder (macOS'es native screen recorder) with this microphone. After recording the screencasts, I used to run a command like the following to replicate audio channel to both ones: 

for file in ./*.mp4; 
do ffmpeg -i $file  -ac 2  -map_channel 0.1.0:0.1 -c:v copy  ./stereo/$file.mp4;
done

This is the only choice I have currently to work around this issue.

vkohaupt commented 1 year ago

According to the log you have a stereo microphone alsa_input.usb-Burr-Brown_from_TI_USB_Audio_CODEC-00.analog-stereo-input

Unfortunately I can't change anything on vokoscreen because I don't have a stereo microphone.

But you could try to set the microphone to mono using pavucontrol. See picture in the attachment

djnotes commented 1 year ago

Thank you. It worked. Now I understand that I can switch the mic to a mono profile using pavucontrol. Interestingly, the output file's audio is stereo and it's heard from left and right speakers. image

vkohaupt commented 1 year ago

You probably have to set a corresponding profile for your Bluetooth headset. See the last post here. A Bluetooth profile might also be listed "High Fidelity AD2P-Bluetooth" https://github.com/vkohaupt/vokoscreenNG/issues/228

This could be another help. https://wiki.archlinux.org/title/PulseAudio/Troubleshooting#Glitches,_skips_or_crackling

djnotes commented 1 year ago

Sorry if my answer was misleading. All of the players I mentioned including VLC only play audio from left speaker. However, in VLC I can make it play from both speakers by switching audio channel to mono from VLC's Audio menu option.
