Audio action
The "Audio" macro action allows you to change the volume level of sources and OBS' master volume, and mute or unmute individual sources.
To change the volume level of an audio source or OBS' master volume first select the corresponding action at (1).
Next select the source of which you want adjust the volume at (2) and enter the desired volume level at (3).
By default, the volume change will apply as soon as the action is performed.
If you should however prefer to fade the volume change over a period of time to smooth the transition click the checkbox at (4).
Next either decide if you either want to specify the rate, at which the fade shall take place, or the duration the fade shall take to complete at (5).
As the volume change will no longer be applied instantly if the fade option is selected situations can arise during which multiple fade on the same audio source are active.
You have to option to cancel any ongoing fades by checking the box at (6).
If you want make sure any following actions of the particular macro the audio action is part of will only be executed once the fade action is complete you will have to tick the checkbox at (7).
To (un)mute an audio source first select the (un)mute action at (1) and next select the source to (un)mute at (2).
