Live Audio Monitor

The Live Audio Monitor allows you to monitor and adjust audio sources in OBS. For all intent and purposes, it mimics the OBS Audio Mixer, with the addition of also being able to take sources on and off air, and adjust any gain filters.

During a run, the runner's game and mic come from their stream - they send their gameplay audio down one stereo channel and their mic down the other. This keeps them synced with their game and webcam. The commentators and host can either be all captured via the Runner's Mic source, or from a Discord source (see Delay Setup for details).

The buttons across the top of each source do the following:

• • GREEN AUDIO: mutes/unmutes the source

  • RED "ON AIR": when red and enabled, this means this source is currently "ON AIR", meaning it can be heard on the stream. When grey and disabled, this source is currently "OFF AIR", meaning it can't be heard on stream, but it can still be heard by you on OBS. These are automatically toggled when using the Live Switch buttons to switch scenes, so outside of an emergency the only time you'll really need to use it is if you want to set Discord to "ON AIR" during intermission so the host can speak, or when changing the Game audio in a multiplayer run.

  • YELLOW "ON AIR": the Music and Video sources are set to a locked yellow "On Air" state. These sources can always be heard on stream, but they are not monitored by OBS. It is worth noting that the Music source on OBS, is actually the Intermission scene's browser source, it's named "Music" so that it makes sense here on the Live Audio Monitor.

  • WHITE 0db: Reset's the source's Gain filter to 0db.

Most sources have two faders, a volume fader on the left, and gain fader on the right. You should always balance audio with the volume fader first, and then add gain if it still isn't loud enough. If at any time a mixer has more than one gain filter, refreshing the page should fix this.

Changing scenes will automatically adjust the panel to only display audio sources on that scene. If a scene has too many audio sources to fit on the panel, the panel becomes scrollable. Audio sources will always be displayed in alphabetical order. If an audio source doesn't have a volume monitor (the coloured bars visualising the sound) then this is because that source isn't active. It is expected for Player 2-4 sources to appear this way during a solo race, because those sources aren't receiving any sound data in OBS. 

Audio sources in OBS are marked with a signifier so they display on the Live Audio Monitor. By default, this is ♪ and whilst it can be changed in the nodecg-obs-control config, this has already been set up to work with STUK's setup. However, should you have an additional source that you need to add to OBS and want to monitor the audio for (such as an external music player or alert overlay), you simply need to add the signifier to the start of the source's name and that will make it show up on the panel.
