Viewers will tolerate a shaky camera. They will not tolerate bad audio. If your church live stream sounds hollow, distorted, or silent — people leave within seconds. Getting your audio mix right for streaming is the single most impactful upgrade most churches can make. Here's how to do it.
Why Stream Audio Is Different from Room Audio
Your front-of-house (FOH) mix is designed for a room full of people sitting 20-100 feet from the speakers. The stream mix is heard through earbuds, phone speakers, and laptop speakers — inches from the listener's ears. These are fundamentally different listening environments.
- Room mix is reinforcement — It supplements what the congregation already hears acoustically. Vocals are loud, instruments are lower because the acoustic sound fills the room.
- Stream mix needs everything — Online listeners hear only what's in the mix. If the acoustic guitar isn't in the stream feed, they don't hear it at all.
- Room mix tolerates dynamics — A loud moment in the room is exciting. The same dynamic spike on earbuds is painful.
This is why sending a direct copy of your FOH mix to the stream often sounds bad. It's mixed for a different context.
The Ideal Setup: A Dedicated Stream Mix
If your console supports it, create a separate aux mix or bus for the stream. Most modern digital consoles can do this:
- Behringer X32 / Midas M32 — Use a mix bus (e.g., Bus 15-16 as a stereo pair) routed to an XLR or 1/4" output
- Allen & Heath dLive / SQ — Assign a mix send for stream output
- Yamaha CL/QL/TF — Use a matrix or mix bus with dedicated output
The stream mix should include every instrument and voice at a balanced level. Think of it like mixing for a studio recording — everything present, nothing overpowering.
If You Can't Do a Separate Mix
Many smaller churches have a board with limited outputs. In that case, use a post-fader aux send from the main mix. This follows your FOH fader movements (so mutes and level changes carry over) but lets you adjust the overall send level independently. It's not ideal, but it's better than a direct tap off the main output.
Getting Audio Into Your Stream
Your audio has to get from the soundboard to wherever it enters the stream. Here are the common paths:
Option 1: Audio Embedder → ATEM
An HDMI audio embedder takes your board's analog output (XLR or 1/4") and mixes it into an HDMI signal. Connect the embedder to an ATEM input, and the audio rides with the HDMI signal. This is the cleanest approach if you're using an ATEM — one cable, no sync issues.
Option 2: USB Audio Interface → OBS
Run an XLR or 1/4" cable from your board's stream output to a USB audio interface (like a Focusrite Scarlett Solo — about $80). The interface connects to your streaming computer via USB. In OBS, select the interface as your audio input. This gives you level meters and per-source control in OBS.
Option 3: ATEM 3.5mm Mic Input
The ATEM Mini has a 3.5mm mic input. You can run a cable from your board's headphone or aux out to this input with an adapter. It works, but the 3.5mm input is noisy and doesn't give you much level control. Use this as a last resort.
Option 4: Digital Direct (Dante, AES67, USB)
If your console supports Dante or USB direct out, you can send a digital stream directly to your encoder computer. Zero analog conversion, zero noise. Dante requires a Dante Virtual Soundcard license or a Dante-to-USB adapter. This is the highest quality option for churches with digital consoles.
Mixing Tips for Church Streaming
- Compress more than you think — Stream audio benefits from heavier compression than room audio. A 3:1 ratio on vocals and 4:1 on drums keeps the dynamic range manageable for earbuds. Your FOH engineer might wince, but online listeners will thank you.
- Roll off the lows — Cut everything below 80 Hz on vocals, 60 Hz on guitars. Low-frequency rumble that's barely audible in the room is boomy and muddy on earbuds. Use a high-pass filter on every channel in your stream mix.
- Check on earbuds — Mix on studio monitors if you have them, but always check on consumer earbuds before Sunday. AirPods, cheap wired earbuds — these are what your viewers use. If it sounds good on those, it'll sound good everywhere.
- The pastor's mic is king — During the sermon, the pastor's voice should be crystal clear with nothing competing. If viewers can't understand the sermon, nothing else matters. Aim for -12 to -6 dBFS on the pastor's voice in your stream output.
- Watch your meters — Stream audio should peak around -6 dBFS and average around -18 to -12 dBFS. If you're hitting 0 dBFS, your stream is clipping and viewers hear digital distortion. If you're averaging -30 dBFS, viewers are cranking their volume and hearing all the noise floor.
- Mute the ambient mics during speaking — Room mics or choir mics that are great during worship add noise and echo during the sermon. Mute them or pull them down significantly when the pastor is speaking.
The Biggest Audio Mistakes We See
- No audio on stream at all — The aux send is off, the cable is disconnected, or the ATEM/OBS has the wrong input selected. This happens more often than anyone admits. Test audio before every service.
- Double audio (echo) — Two audio sources active: board feed AND a camera mic. Mute camera mics in the ATEM audio mixer. Always.
- Clipping/distortion — Levels are too hot somewhere in the chain. Turn down the aux send or reduce the output gain until peaks stay below -6 dBFS.
- Background hum — Ground loop between the soundboard and the streaming computer. Use a ground loop isolator ($15 on Amazon) or go fully digital with USB/Dante.
- Inconsistent volume between songs and sermon — The worship team plays at -6 dBFS but the pastor speaks at -24 dBFS. Use compression on the stream bus or ride the master fader. Better yet, use a limiter on the stream output to catch peaks.
Monitoring Stream Audio with Tally
Tally monitors your audio console alongside your video gear — so audio problems don't go unnoticed:
- Audio level monitoring — Tally tracks whether audio is present in your stream. If the stream goes silent (muted channel, disconnected cable, crashed software), you get an instant alert on Telegram.
- Full mixer control from your phone — Adjust faders, EQ, compression, gates, and mute/solo on every channel from Telegram. Works with Allen & Heath, Behringer X32, Midas M32, and Yamaha consoles.
- Preset recall — Save your stream mix as a preset and recall it with one command. "Load stream preset" brings every fader, EQ setting, and bus level back to your proven configuration.
- Pre-service audio check — Tally verifies your audio console is online and responding 30 minutes before service. If the console lost power or the network cable came loose, you know before the worship team starts playing.
Audio is the foundation of a good stream. Get the mix right, monitor it actively, and your online congregation hears every word. Start a free trial and connect your audio console to Tally in under 10 minutes.
