Church and worship multi-mic phase: sanctuary close/OH/room vs stream and broadcast fold
Worship vocals, band, and room mics feel rich in the sanctuary and in FOH headphones. On the stream or broadcast bus, phones, YouTube, and Facebook Live often thin the pastor, collapse choir body, or hollow the band. That is usually polarity and arrival time between close, OH, and room paths that share the same content a few milliseconds apart, plus a stereo mix that was never folded to mono before send. Fix polarity and small delays first. Frequency-aware phase repair belongs only after residual L/R fights remain on stereo beds before mono fold.
Download PHIXER free PHIXER hub
PHIXER is free stereo phase-repair (VST3/CLAP/AU · Win/Mac/Linux) from Riverflux Audio. Frequency-aware phase rotation for leftover L/R fights on stereo material. It is not a worship compressor, not a widener, and not a substitute for sanctuary gain structure or mono audition of the stream bus. Polarity and timing first; PHIXER after residual spectral fights.
What church / worship phase failure sounds like
- Pastor lav + boom + room thin on stream. Dual speech paths share the voice a few ms apart.
- Choir spots huge in house, hollow on YouTube / Facebook Live. Spots and OH/room cancel body on fold.
- Band OH + stage wedges bleed into stream bus. Same content twice with different delay.
- Stereo sanctuary bed collapses on phone. Hard L/R keys or pads disappear when the platform folds.
- Fine in FOH cans, broken for remote viewers. Same destinations as live FOH / stream, OBS livestream, YouTube / social, and broadcast.
Fast mono audition (about 60 seconds)
- Solo the stream / broadcast / matrix bus (not only FOH). Flip a utility to mono.
- A/B close muted vs open under OH/room. Note what disappears: speech chest, choir body, kick/bass, pad warmth.
- Solo pairs: pastor lav vs boom, choir spots vs OH, band OH vs room, stereo keys vs mono fold.
- Check correlation on the stream bus, then with music muted vs unmuted (correlation meters).
Order of operations (before spectral phase rotation)
1. Polarity between close, OH, and room
Flip speech lav vs boom, choir spots vs OH, or band close vs room when body returns immediately. Guide: polarity vs phase. Related live habit: live FOH / foldback / stream.
2. Small delay align closes to the room / OH
Close mics arrive earlier than OH or sanctuary room. A few samples of delay on closes (or nudge to the room) often restores body better than any widener. Different job from spectral repair: vs time-align.
3. One hero speech path to the stream bus
Do not send lav + boom + room all hot into the livestream matrix. Pick a hero for speech, keep backups muted or low. Parallel stacks are classic hollow-voice on phone fold. Related: dual-mic phase, podcast dual-mic.
4. Prefer OH/room as the band image; quieter stage closes
Stage closes should color, not replace OH/room for the stream mix. If every close sits at full level under loud OH, mono fold almost always hollows. Pull closes first. Related: overhead & room.
5. Skip wideners and Haas on worship beds before fold
Short-delay width and stereo imagers make sanctuary headphones huge and phones hollow. Guides: vs imagers, Haas vs phase repair.
6. Only then audition residual L/R spectral fights
If a stereo bed (keys, pads, stereo choir print, stereo room) must stay stereo and fold still hollows a band after the steps above, gentle frequency-aware phase rotation can help. Prove it with mono A/B, rotator bypassed vs engaged.
Path types and typical failure modes
| Path | Common mono failure | First fix |
|---|---|---|
| Pastor lav + boom (+ room) | Chest or presence cancel on stream | One hero path; polarity; delay |
| Choir spots + OH / room | Body disappears on YouTube / FB Live | Polarity + delay spots; quieter spots |
| Band closes + OH | Kick/bass/pad thin on phone fold | Hero OH; pull closes; polarity |
| Stereo keys / pads hard L/R | Huge in cans, gone on phone | Center critical content; simplify width |
| FOH matrix → OBS / encoder | Fine in house, hollow for viewers | OBS livestream mono check |
| TV / radio / LoRo print | Fine in suite, hollow on air | Broadcast · LoRo |
Worship stream checklist (to send)
1. Label sanctuary vs stream paths
Name closes, OH, room, and matrix sends so operators know what hits the livestream. Ambiguous stacks get left open and comb on fold.
2. Mono-check stream bus alone, then with music
Solo speech in mono. Then open band and choir in mono. Note fights between speech and music beds, not only inside one group. Related: choir / ensemble.
3. Watch phone and social destinations
Most remote viewers hear mono or near-mono. Guides: YouTube / social, Twitch / OBS, phone / BT.
4. Optional null / mono workflow before service
Host-agnostic habit before you go live: DAW null-test + mono-check, master bus mono checklist.
When PHIXER belongs on worship-related stereo
- The material is already stereo and must stay stereo (stereo room pair, stereo keys bed, stereo choir print), not a mono lav you fake-widened.
- Polarity, delay align, and hero-path levels are cleaned up, but fold still hollows a band of the spectrum.
- You can A/B mono with the plugin bypassed and hear clearer body without wrecking the image.
- You are not using it to "fix" unaligned lav+boom under a room, or to replace a time-align edit on the matrix.
Decision table
| You notice… | First try | Why |
|---|---|---|
| Speech lav + boom hollow chest | One hero; polarity; delay | Arrival-time fight |
| Choir + OH collapses on stream | Polarity; delay spots; quieter spots | Stacked identical content |
| Band fine in house, thin on phone | Mono stream bus; pull closes | FOH ≠ viewer fold |
| Stereo room / keys still cancels by band | PHIXER on that stereo bed | Residual spectral L/R fight |
| Mono lav alone is dull | Tone / EQ / gain / mic choice | Not an L/R repair job |
When NOT to use PHIXER here
- You have not mono-auditioned the stream / matrix bus yet.
- The fix is obviously polarity, delay, one hero speech path, or quieter closes under OH.
- You want PHIXER to make worship louder, wider, or "more immersive." Wrong job.
- The speech path is mono and the print problem is balance or EQ.
- See also when not to use PHIXER.
Quick path: Solo stream bus in mono → polarity close vs OH/room → delay-align closes → one hero speech path → quieter stage closes under hero OH/room → skip Haas/imagers → mono-check with band/choir → PHIXER only for leftover stereo cancellation on a bed → fold again for YouTube / Facebook Live / phone.
