One of the most powerful tools available to you for audio in OBS, “Advanced Audio Properties” will give you the power to do a lot of really useful things.
If you don’t have OBS, you can download it at https://obsproject.com/ .
To access this tool, You will simply need to do the following
- Open OBS
- Click “Edit”
- Alternatively, left click the gear within the audio “Mixer” window
- Click” Advanced Audio Properties”
All of your Audio channels you may have created will be in here. Yours will look different from this.
Features within “Advanced Audio Properties”
Notice that my setup has special names. You can find out how to do that and much more in our other guide:
“Volume(%)” shares functionality with the Mixer window in OBS, in that it turns down audio that the stream hears while preserving the volume that you yourself hears.
This feature is especially important for you because you are able to maintain an ideal volume for stream digestion while allowing you to listen to it at whatever volume you desire(Or not at all!)
“Down-mix to mono” is a tool that simply copies a mono track into whatever format is specified in OBS.
“Balance” is simply how far to the left or right your microphone will be panned. This means it becomes louder in one channel and quieter in another. For a single voice, leaving this centered is preferable.
If you have a multiple person stream, panning one microphone left, and the other microphone right, will make the content seem more natural.
“Sync offset” is used to delay audio from the video, which is used to ensure the audio is synced to the lips. This is especially important, as de-synced audio from lips is incredibly jarring to your viewers.
Depending on your setup, you may not need any “Sync Offset” at all.
The most powerful feature in this tool
“Audio Monitoring” is an especially important feature, in that you can use it to monitor in near-real time any audio source you have into your designated “Audio Monitoring Device”.
An Audio monitoring device can be assigned in the advanced settings in OBS.
Assign your headphones to this. If your headphones are attached to your Audio Interface, choose that instead and ensure your mix knob is centered.
- Go into Advanced Audio Properties window
- Select “Monitor and output” For microphone
- You can now hear yourself exactly as the stream would. Great for debugging!
- You can do this for any device.
Tracks Are also a powerful tool at your disposal
Finally, We have “Tracks.” Tracks are only important for recording purposes. If you only stream, you are free to ignore this section, However, if you record, It is advised to separate each device onto its own track, except track 1, Which is passed to your stream by default.
This may change in the future if the streaming services like Twitch or Mixer offer multi-track support, A feature I really wish they had. Doing so will allow streamers to mute out music tracks, or replace them in case of copyright changes to any audio used in stream vods without losing game audio or voice commentary should portions be muted due to automated systems(I’m looking at you, article 11/17/13!!). Pretty please Guys!
To exclude a track from the stream, deselect Track 1 for the device(The default track output to stream) And select “Monitor only(Mute output)”.
OBS can have a maximum of six tracks at this time, meaning that if you have any additional Audio sources beyond five, due to one reserved to your master track, you need to combine two sources to one of those five.
Doing this will make editing in your video editor of choice a lot easier to edit, and is considered best practice.
