Audio Settings

OBS Studio does not know about mono channels, only stereo channels. This causes 2 problems:

  1. 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”.
  2. 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, use ffmpeg with the -ac 1 option:

$ ffmpeg -i "stereo_but_only_one_channel.mkv" -ac 1 "mono.mkv"

Downmixed video.

Source Record Plugin

The Source Record plugin for OBS Studio provides a filter for sources and scenes that allow them to be individually recorded into separate files.

OBS Log Analyzer

The analyzer reviews an OBS log file for common issues and problems and provide suggestions for how to solve them. This innovative web-based service works very well.

The Log Analyzer does not yet process crash logs.

There are 2 ways to upload the OBS log file for analysis:

  1. This method requires OBS Studio to be functional. In OBS Studio, select Help > Log Files > Upload last Log File. Copy the URL and paste it here.
  2. This method can be used without running OBS Studio. The directories for OBS Studio log files for each supported OS are:
    • Windows: %AppData%\obs-studio\logs
    • MacOS: ~/Library/Application Support/obs-studio/logs
    • Linux: ~/.config/obs-studio/logs
    From this page, choose the log file and upload it, then press the Analyze button.

Here are the results of a log analysis:
