Hey there, welcome in! In this article, I’ll be covering the various components and features within one of OBS Studio’s most powerful audio tools: The Advanced Audio properties. Essentially, all this semi-hidden window does is give you fantastic control of your audio signal chain.
Every single audio source that you add will be in here, including webcam mics and other things. Your list will likely look different from this one, as this has been customized for my needs.
A list of features within this tool
|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!)|
|Status||An indicator of whether or not a source is enabled, and is being sent to an audio track.|
|Down-mix to mono||Enabling this simply sends the first track to all tracks within the source. In newer versions of OBS, this is simply “Mono”.|
|Balance||A setting to define the stereo panning of the audio signal. What it does, is cause the signal to become louder in one ear and quieter in another. In most cases, you want this to be directly in the center.|
One use case where you will want a signal panned, is if you have a multiple person stream. Panning one microphone a little bit to the left, and the other microphone right will make the content seem more natural to our senses and gives your audience subtle cues of who is speaking.
|Sync Offset||This setting will add an artificial delay to your audio signal to help match the audio up to a video that has a delay to it. Typically, it is utilized for capture card based webcams that have naturally high latency.|
In most cases, you do not need Sync offset, and it should be avoided.
|Audio Monitoring||Audio Monitoring is the main reason I recommend you guys to be familiar with the Advanced Audio Properties. It 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” in your audio settings. It used to be under the Advanced tab in earlier versions but was moved to Settings – Audio in a fairly recent update.|
|Tracks||Tracks are used primarily for recorded content. They determine what audio source is output to a specified audio track. Up to 6 tracks are currently available. It is my hope that streaming platforms and OBS Studio add support for multiple audio tracks support.|
The most powerful feature in this tool
“Audio Monitoring” is easily the most powerful feature available in OBS for Audio. The only other feature that comes close to this in power is OBS’s support for VST plugins.
To utilize this feature, you must navigate to settings, Audio, and designate an Audio monitoring device. I use my Audio Interface in the above image, but you should use whatever device that your headphones are attached to.
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 Glimesh 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. It would make the DMCA process a much simpler beast to manage, I’ll tell you that.
