Didgeridoo / Aboriginal drone multi-mic phase: mouthpiece, bell, and outdoor/livestream fold vs OH and room
Close spots on didgeridoo mouthpiece, mid-tube, and bell feel huge and circular-breathed in the booth, on stage, and in cans. On phone speakers or YouTube mono fold, drone fundamental, Mid, and vocalized overtones often thin or cancel against stereo OH, room, and outdoor PA paths that carry the same breath a few milliseconds later. That is usually polarity and arrival time between spots and shared beds, plus a stereo bed that was never folded 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. Distinct from bagpipes and general woodwind: this page is about Aboriginal didgeridoo drone (and clapsticks/voice companion beds) alone, including outdoor and livestream fold. Cross-links: bagpipes, woodwind, field recording, livestream, YouTube mono, percussion.

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 compressor, not a widener, and not a substitute for mic placement or mono audition of the stream or mix bus. Polarity and timing first; PHIXER after residual spectral fights.
What didgeridoo / Aboriginal drone multi-mic phase failure sounds like
- Circular-breath drone huge in cans, thin on phones. Close mouthpiece/bell spots share the same air column a few ms apart from stereo OH or outdoor room.
- Vocalized overtones and toot hollow on YouTube. Spot + stereo bed + room/PA stack cancels Mid when the platform folds.
- Bell body present on stage, gone on phone. Hard L/R across mouthpiece and bell paths collapse on mono fold.
- Didgeridoo hero vs clapsticks / voice / guitar bed fight. Companion beds and drone spots share low-mid energy without polarity hygiene.
- Fine in headphones or FOH cans, broken for outdoor livestream viewers. Same destinations as YouTube / social mono, OBS livestream, field recording, bagpipes.
Fast mono audition (about 60 seconds)
- Solo the stream / mix / FOH bus (not only stage headphones). Flip a utility to mono.
- A/B didgeridoo mouthpiece/bell spots muted vs open under stereo OH, room, or outdoor PA. Note what disappears: drone fundamental, Mid, overtones, breath edge.
- Solo pairs: mouthpiece vs bell, didgeridoo vs clapsticks/voice bed, spot vs OH/PA.
- Check correlation on the delivery bus, then with the full outdoor or ensemble bed muted vs open.
Order of operations (before spectral phase rotation)
1. Polarity between spots and shared OH / room / PA
Flip mouthpiece or bell spots vs stereo OH/PA, or didgeridoo vs companion bed, when fundamental or Mid return immediately on a clear drone. Guide: polarity vs phase. Cousins: bagpipes, woodwind, field recording.
2. Small delay align secondary paths to the hero drone image
OH, room, and outdoor PA often arrive later than close mouthpiece or bell spots. A few samples of delay on the secondary often restores fundamental better than EQ for "more drone."
3. One hero didgeridoo image to the stream or mix bus
Do not send every mouthpiece, mid-tube, bell, and OH/PA all hot into the livestream or outdoor print. Pick a hero Mid-safe bed (often a focused stereo OH or lav+boom pair plus selective spots), keep extras muted or low. Parallel stacks are classic thin-drone on phone fold. Related: field recording, overhead & room.
4. Prefer hero mouthpiece / bell as the tone; quieter color spots
Secondary closes should color proximity and overtone identity, not replace the hero image for the stream mix. If every close sits at full level under a loud OH or PA, mono fold almost always hollows the drone bed.
5. Skip wideners and Haas on didgeridoo beds before fold
Short-delay width and stereo imagers make stage cans shimmer and phones hollow. Keep critical low-mid and drone fundamental centered for stream, outdoor PA, and print.
6. Only then audition residual L/R spectral fights
If a stereo bed 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 |
|---|---|---|
| Mouthpiece/bell spots + stereo OH | Fundamental / Mid cancel on stream | Polarity; delay secondary; quieter secondary |
| Didgeridoo spot + room / outdoor PA | Hollow overtones, thin drone | Polarity + timing; hero Mid-safe path |
| Didgeridoo + clapsticks / voice / guitar bed | Hero vs companion fight on phone | Polarity + delay; hero image |
| Stereo pair hard L/R across mouthpiece/bell | Huge in cans, thin on phone | Center critical lows; simplify width |
| Board / matrix → OBS / YouTube / outdoor fold | Fine on stage, hollow for viewers | OBS livestream / YouTube mono / field |
Studio / livestream checklist (to send)
1. Label spots vs OH vs room vs outdoor PA vs companion bed
Name mouthpiece, mid-tube, bell, clapsticks/voice, stereo OH, and PA so operators know what hits the livestream or outdoor print. Ambiguous stacks get left open and comb on fold.
2. Mono-check delivery bus alone, then with full outdoor / ensemble bed
Solo drone fundamental and Mid in mono. Then open overtones and breath edge in mono. Note fights between secondary color and hero bed.
3. Watch phone, YouTube, outdoor livestream, and social destinations
Most remote viewers hear mono or near-mono. Guides: YouTube / social mono, OBS livestream, field recording.
4. Re-check after wind / stand / player-position moves
Outdoor wind screens, mic height, and player angle change distance and bleed. Flip polarity again after you move stands, change OH height, or re-position for wind.
When PHIXER helps
- The material is already stereo and must stay stereo (stereo OH, stereo room or board/outdoor print), not a mono close 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 fundamental or Mid without wrecking the image.
- You are not using it to "fix" unaligned spot+OH under outdoor PA, or to replace a time-align edit on the matrix.
Decision table
| You notice… | First try | Why |
|---|---|---|
| Fundamental thins when OH/PA opens under spots | Polarity; delay secondary; quieter secondary | Arrival-time fight |
| Didgeridoo + clapsticks/voice harsh and hollow | Polarity; timing; hero Mid-safe path | Dual-path spot + companion |
| Fine on stage, thin on phone / livestream | Mono delivery bus; pull extras | Stage ≠ viewer fold |
| Stereo bed still cancels by band | PHIXER on that stereo bed | Residual spectral L/R fight |
| Mono didgeridoo 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 / mix / FOH bus yet.
- The fix is obviously polarity, delay, one hero image, or quieter secondary under spots/OH/PA.
- You want PHIXER to make the didgeridoo louder, wider, or "more drone." Wrong job.
- The path is mono and the print problem is balance, wind noise, or EQ.
- See also when not to use PHIXER.
Quick path: Solo delivery bus in mono → polarity spots vs OH/room/PA → delay-align secondary → one hero image → quieter extras under hero → skip Haas/imagers → mono-check with full outdoor/ensemble bed → PHIXER only for leftover stereo cancellation on a stereo bed → fold again for stream / outdoor / studio print.
