Mixing for Streaming: Aiming for Smooth, Consistent Broadcast Audio

If you have assembled your final mix from your FOH console or even a dedicated broadcast room, begin to study the recorded mix in as many types of listening spaces you expect your viewer to listen from.

It means there is more happening after you are done mixing.  This also will make you think about your stems upstream in your mix, and leaving headroom there allows for a cleaner delivery to your final mix.

For your final mix heading for livestream, a good starting point with your brick wall limiter is setting your threshold to -10db and your ceiling also at -10db.

In your video room, adjust your level feeding your livestream software to leave about -6db of headroom as a starter to ensure you don’t clip your livestream encoders.

The reasoning for -6db is digital encoder systems have an absolute maximum ceiling of 0 dBFS. Ddepending on the manufacturer encoder used, though, overshoots and spikes of 2 to 3db can occur. Leave headroom, as you can fine-tune those levels to be tighter, once you can predict any encoder spikes.

If the final product is an archive video, you can go all the way up to -2db with the limiter ceiling, as this is your final product and not being delivered elsewhere.

To Wrap This All Up …

Finalizing your broadcast audio takes some tweaking. The goal of bringing you these guidelines is to get you closer to understanding some benchmarks that you can fine tune to produce a broadcast that is distraction free, for its intended audience.

House of worship video production is not like mainstream TV broadcast (unless you happen to actually televise), due to the use of so much varied equipment choices for churches to purchase.

There won’t be a one-size-fits-all here, and as we know, many of you may be rockin’ it with simple home consumer equipment. However, it’s my hope that this gives you encouragement and a greater picture that excellent broadcast or post audio is obtainable and only a few polishes away.
