Live Stream Audio Capture & Mixing (Live Stream Church 2020) [Part 3 of 4]  

Audio capture is the way that you take all that audio that’s going on in your church service, mixing it, and piping it into your livestream so all the people watching feel like they are right there with you!
Bad audio is the number 1 killer of your church’s livestream. Some common problems on live streaming audio are volume levels that are either super quiet, crazy loud and distorted, poorly mixed, buzzing, poorly eq’ed, flat and dead sounding, and out of sync with the video.
1. Capturing Your Audio
a. Computer Mic/Line Input - Almost all computers have an 1/8th inch line input on the motherboard of your computer. The line input is normally colored blue. You can connect a mixer’s XLR, 1/4” or RCA plugs to your motherboard’s line input with cables like these. I do not recommend using these connections unless you absolutely have no other choice.
b. Camera Line/Mic Input - Many cameras have one or more physical audio inputs. These inputs are typically either an 1/8th inch or XLR port. This will convert the audio into digital and most of the time will embed the audio along with the video out of the camera’s HDMI or SDI output. Your computer can then capture your audio along with the video when it is fed into your capture device. I do NOT recommend feeding your audio through your camera’s audio input.
c. Audio Interface - An audio interface is an external (and sometimes internal) hardware device that typically connects to your computer using USB, Firewire, Thunderbolt or PCI-E if it’s an internal card. My inexpensive go-to audio interface is the Behringer UMC202HD. If you have a digital mixer, oftentimes they will be actual audio interfaces in and of themselves. For example, the Behringer x32 is not only a digital audio mixer, it’s also a giant USB audio interface right out of the box.
d. Network Audio - On your Windows PC, you can install the Dante Virtual Soundcard and Controller software. This creates a virtual audio input on your computer that allows you to receive any Dante audio channels that are on the network you are connected to. Audinate, makes a very inexpensive yet powerful line of adapters called Dante AVIO adapters. These 2 adapters can take either a stereo analog XLR output from your mixer or a digital AES/EBU connection via XLR, like the one in the x32, and convert it to Dante.
2. Mixing Livestream Audio
a. Main Mix - The first and quickest way to mix your livestream audio is to simply capture your main Left and Right signal coming out of your mixer.
b. Post-fader Aux Mix - Another way to mix your live stream audio is using a post fader aux mix out of your mixer. A post fade mix is when the level going to your livestream is connected to the physical faders of the channels.
c. Pre-fader Aux - This method employs a dedicated person mixing an aux mix on your mixer. Monitoring could be done via a headphone output on the mixer or through the computer that is capturing the audio for live stream.
d. Separate Mixer Mix - Some digital mixers like the Behringer x32 have the ability to share all of the channels of the mixer with another mixer. For example, you can plug in 1 x32 to another x32 via the 2 AES50 ports on the back of each mixer. This gives the second x32 a copy of all of the channels, independent of the first mixer.
e. Live DAW Mixing - Live DAW (Digital Audio Workstation) mixing is similar to the previous method, however, instead of mixing on a second mixer, you would be mixing within a software program like Pro Tools. The advantage of this method is the power and versatility of software mixing. There are very high quality audio plugins made by companies like Waves, Slate Digital, Universal Audio, iZotope and more. With the x32, this is achieved by installing the Dante card
