Setting Audio Levels for Multi Person Livestreams Using a Loudness Meter - Youlean

Have you ever hosted a livestream with remote guests on a service like Streamyard, and then learned in horror from your audience that they can barely hear one person while another person is super loud?

In this episode, we have a look at one way to set your audio levels when you have multiple participants in a livestream on services like Streamyard, Restream.io, Riverside.fm, and other cloud based streaming services. Instead of using simple peak meters, we demonstrate how to use a loudness meter which is much better at getting everyone’s audio levels to the same target so that your audience can focus on the stream.

If you’d like to learn how to make great dialogue audio for your film and video projects, please have a look at my courses including processing dialogue audio in Adobe Audition and DaVinci Resolve/Fairlight, recording sound, how to use the Zoom F4, F6, F8, and F8n, and how to get the most from the Sound Devices MixPre series of recorders. Our latest course is Sound for Live Streaming with the ATEM Mini.

Understanding How to Loudness Normalize Your Audio for Video

In a previous episode, we covered the difference between volume and loudness and introduced the loudness metrics LUFS and LKFS. In this video, we talk about how to loudness normalize the audio for you videos in conceptual terms with a practical example. For the example, we edit our video and mix the audio in DaVince Resolve and then loudness normalize the audio mix in Izotope RX. But the goal here is to show you the concept so that you can adapt loudness normalization into your workflow.

Please watch part 1 first where we cover loudness, LUFS, and LKFS.

Audio Loudness in Final Cut Pro X with Free Plugin from Youlean

For those who edit in Final Cut Pro X, ensuring that your audio was loud, but not too loud, and consistent from video to video has been a challenge. Of course you could buy expensive plugins to help with this and often what the pros do (it’s the cost of doing business and broadcasting your pieces on TV). But for those who are mainly publishing to the web and working on VLOGs or passion projects, the budget for expensive software or hardware loudness meters just wasn’t there.

Recently I found a free loudness plugin by Youlean which you can get over at Youlean. **NOTE** Several notified me that the Youlean site appears to display spam types of messages and opens new tabs. Close these windows and do NOT click on the links in them. I have notified the site owner and hopefully they can fix this soon.

And once you have that installed, you can get the right loudness consistently with the technique we show here.

For those not familiar with loudness normalization, here are a couple of other pieces where we go into some detail on how it works:

How to Get Consistently Loud Sound with Loudness Normalization

In the last episode we covered how to set the input or gain level on your audio recorder when recording dual system sound (sound recorded by a separate, dedicated audio recorder). One of the things I suggested was that it is best to leave some headroom so that if the person speaking suddenly gets very loud, the sound will not distort and clip.

But the problem is that most of the sound isn’t loud enough. So how do you manage this? You loudness normalize the audio. This ensures that it is loud enough and that it is consistent from video to video.

Here are three ways to do that. The third way is to manually loudness normalize and is a longer, more involved process. You can see how to do that here:
