OBS Studio does not know about mono channels, only stereo channels. This causes 2 problems:
The left and right channels are hard panned left and right, which is seldom what you want.
To center the channels, go to Edit / Advanced Audio Properties, and enable “Mono”
for the channel pair, which means “downmix to mono”.
- OBS Studio has no provision for adjusting the volumes of the left and right channels independently. Use RME TotalMix to adjust the mix for the AES Loopback channels.
Downmix Stereo to Mono
To change a file (audio or video) from stereo, with only one channel recorded, to mono,
ffmpeg with the
-ac 1 option:
$ ffmpeg -i "stereo_but_only_one_channel.mkv" -ac 1 "mono.mkv"
