Audio Tips for Live Streaming

How to Fix the Audio Issues on Your Live Stream

This post covers troubleshooting tips for your live stream audio: fixing levels that are too high or low, audio buzzing, or how long to run your audio cables. It's the main post in our series on audio tips for live streaming.

Have you ever watched a video with no audio or really bad audio? If it is play-by-play commentating for a sporting event or your church's choir singing its best song, your viewers want the audio to be great.  In this article, we will discuss how to fix audio issues you might be having.


Is It Bad to Have No Audio?

A live broadcast that has no audio can be painful to watch. If you aren’t able to provide an audio feed, any audio is better than no audio for your viewers. Even if it is just from the camera microphone picking up the speaker or the ambient sounds of the event, your viewers will appreciate knowing that it is not broken.

If you must stream without audio, you might try using our BoxCast Graphic Overlays feature to add an overlay saying something like: “Unfortunately, this live stream does not have audio.”

My audio levels are too low or high

If you are getting audio from a soundboard, try turning the levels up or down a little bit from the soundboard. Also check to see if there is equipment in the path of your audio that has adjustments you can make that might affect the audio signal. For example, if you are using a direct box (“DI box”), check to see if there is a “pad” switch that you can toggle. Many boxes have these switches, which can be used to lower the level of the signal (or, maybe the pad was already switched on and disengaging it will make your signal louder).

With BoxCast, we offer a feature called Low Latency Preview, which can help you monitor and troubleshoot the audio of your broadcast.

How do I fix a buzzing noise in my Stream?

Buzzing or audio noise can come from a lot of things. It can come from the cables, audio mixer, or directly from the source audio, like a microphone or another sound source. This post goes into more detail on what might be causing the buzz and how to troubleshoot those kinds of issues:

It could be an issue with mixing unbalanced and balanced audio signals. Here's more on what that means and how to combat it:

How long can I run my audio cables?

The most common cables used for audio in the video production space are RCA, ¼ inch and XLR. Unbalanced connections like RCA and ¼ cables should be run as short as possible to avoid noise issues - 25 feet is the maximum length that you should ever run.  XLR cables send a balanced signal, so they can generally be used up to several hundred feet.  

As a general rule, you should try to use cables that are the length you actually need (with a little slack). Don’t use a 100’ cable when a 20’ will do, unless you absolutely must.
