Record only mono audio (with ability for stereo downmix, left only, or right only) [feature-request] #323
Comments
AFAIK there is no option for 'left only mono' in ALSA - mono just means mono. What I can do is record in stereo and throw away one of the channels. Or I can record in mono and let ALSA do the downmixing automatically (but then I can't pick a channel). This sounds like a strange setup, are you sure that your microphone is working properly? I know there are mono microphones that use one of the channels to provide a supply voltage and send a signal on the other channel, but if your laptop isn't providing a supply voltage then this wouldn't work anyway. And if your laptop is providing the supply, then it must somehow realize that the microphone is mono and shouldn't be recording both channels in the first place ... This sounds like a very niche problem, I don't want to clutter the GUI with options that 99% of all users won't need. But I could add some kind of custom option for this once the new GUI is ready. Anyway, here's a temporary workaround. Create a file named '.asoundrc' in your home folder with this content:
Now restart SSR and select 'Mono microphone'. ALSA will downmix (i.e. average left and right) which is not what you want, but it's probably better than stereo. |
or you could follow the arch pulseaudio wiki for getting pulseaudio to correctly map audio to both left and right or what have you. a lot of higher end mics do the same to people in skype in linux so there's a workaround to get pulseaudio or alsa (i forget) so that it maps the audio to both left and right. good luck |
Thank you.. this is an awesome workaround ^_^ I dont know the external mic works this way. But when I connect my mic it's just the left signal. same when in Audacity. But in Audacity I can just set input to mono and leave it at that (it's probably downmixing, but it's okay for me) |
I have a mono external mic and have the same results. |
That is normal behavior for mono mic. The pulse audio and jack do the same for mono mics: all sound is on the left channel, the right channel is empty. Therefore the program option to record mono mic is very needed. Many programs even do autodetection for mono mics. |
+1...really needed |
OK, I've found a workaround to record left channel only as mono just using PulseAudio. It took me about two hours just to find this information and apply it correctly. So let's hope it will save you some time guys.
My source name is
Restart the daemon:
It will create a new virtual source called in my case |
I've compiled the latest version and this trick doesn't work :( |
Hey everybody another workaround. Turn the video into mono video after the fact using ffmpeg Run this command on the video to turn it into audio:

This solution worked for me, thanks a lot |
Another solution for ALSA users is to add this to your
Then select If you want the same for the right channel, use this:

WRT, how can I record stereo on a MIC? I am getting a MONO channel/sound on my LEFT earphone and a very faint sound on the right.. I want STEREO. (asked everywhere no luck) I've plugged the MIC into the pink desktop socket - i can record mono just fine - I want stereo. module-remap-source |
Most microphones are mono. If you want stereo you either need a special stereo microphone or you need two mono microphones that you manually set up on the left and right side. |
On mine first this didn't work, since on mine the sound only on my right speaker, then I change

Hey guys! When I try the solution I get the following message: load-module: command not found |
Thank you for SimpleScreenRecorder, awesome software! :)
My notebook's internal sound card has "Stereo Input", however when connecting a mic, only the left channel has sound. This generates a video with audio panned to the left.
Please make an option to choose audio/sound recording mode:
A bit related to #310.
