Hurdy-gurdy / wheel fiddle multi-mic phase: drone + melody vs room/OH and European folk fold
Close spots on the hurdy-gurdy melody keys and drone strings feel huge in the booth and in cans. On phone speakers or YouTube mono fold, melody attack, Mid, and continuous drone body often thin or cancel against stereo OH and room paths that carry the same phrase a few milliseconds later. Medieval and folk ensemble beds (bagpipes, fiddle, percussion) stack the same problem. That is usually polarity and arrival time between melody/drone 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 accordion: this page is about European hurdy-gurdy / wheel fiddle (and medieval/folk companion beds) alone. Cross-links: bagpipes, accordion, bluegrass, field, woodwind, livestream.

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 hurdy-gurdy / wheel fiddle multi-mic phase failure sounds like
- Melody key attack huge in cans, thin on phones. Close melody or drone spots share the same phrase a few ms apart from stereo OH or room.
- Warm drone bed hollow on YouTube. Spot + stereo bed + room stack cancels Mid when the platform folds.
- Buzzing trompette and wheel buzz present in booth, gone on phone. Hard L/R across drone and melody paths collapse on mono fold.
- Hurdy-gurdy hero vs bagpipe / fiddle / percussion bed fight. Medieval and folk ensemble beds and wheel-fiddle spots share mid energy without polarity hygiene.
- Fine in headphones, broken for livestream viewers. Same destinations as YouTube / social mono, OBS livestream, bagpipes, field recording.
Fast mono audition (about 60 seconds)
- Solo the stream / mix bus (not only booth headphones). Flip a utility to mono.
- A/B hurdy-gurdy melody/drone spots muted vs open under stereo OH and room. Note what disappears: melody bite, Mid, drone body, trompette buzz.
- Solo pairs: melody vs drone, hurdy-gurdy vs bagpipe/fiddle bed, spot vs OH.
- Check correlation on the delivery bus, then with the full medieval/folk ensemble bed muted vs open.
Order of operations (before spectral phase rotation)
1. Polarity between melody/drone spots and shared OH / room
Flip melody or drone spots vs stereo OH, or hurdy-gurdy vs companion bed, when body or Mid return immediately on a clear phrase. Guide: polarity vs phase. Cousins: bagpipes, accordion / bandoneon, bluegrass string band.
2. Small delay align secondary paths to the hero hurdy-gurdy image
OH and room often arrive later than close melody spots. A few samples of delay on the secondary often restores body better than EQ for "more wheel."
3. One hero hurdy-gurdy image to the stream or mix bus
Do not send every melody, drone, room, and OH all hot into the livestream or print. Pick a hero Mid-safe bed (often a focused stereo OH plus selective melody or blended drone spot), keep extras muted or low. Parallel stacks are classic thin-hurdy-gurdy on phone fold. Related: overhead & room.
4. Prefer hero melody/drone blend as the tone; quieter color spots
Secondary closes should color proximity and trompette identity, not replace the hero image for the stream mix. If every close sits at full level under a loud OH, mono fold almost always hollows the wheel-fiddle bed.
5. Skip wideners and Haas on hurdy-gurdy beds before fold
Short-delay width and stereo imagers make booth headphones shimmer and phones hollow. Keep critical low-mid and drone body centered for stream 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 |
|---|---|---|
| Melody/drone spots + stereo OH | Body / Mid cancel on stream | Polarity; delay secondary; quieter secondary |
| Hurdy-gurdy spot + room / OH | Hollow melody attack, thin drone | Polarity + timing; hero Mid-safe path |
| Hurdy-gurdy + bagpipe / fiddle bed | Hero vs companion fight on phone | Polarity + delay; hero image |
| Stereo pair hard L/R across melody/drone | Huge in cans, thin on phone | Center critical lows; simplify width |
| Board / matrix → OBS / YouTube | Fine in booth, hollow for viewers | OBS livestream / YouTube mono |
Studio / livestream checklist (to send)
1. Label melody vs drone vs OH vs room vs companion bed
Name melody, drone, trompette, stereo OH, and room so operators know what hits the livestream or print. Ambiguous stacks get left open and comb on fold.
2. Mono-check delivery bus alone, then with full medieval/folk ensemble bed
Solo drone body and Mid in mono. Then open melody keys and trompette buzz in mono. Note fights between secondary color and hero bed.
3. Watch phone, YouTube, and social destinations
Most remote viewers hear mono or near-mono. Guides: YouTube / social mono, OBS livestream, TikTok / Reels / Shorts.
4. Re-check after stand / seating / wheel-angle moves
Instrument angle and mic height change distance and bleed. Flip polarity again after you move stands, change OH height, or re-seat the player.
When PHIXER helps
- The material is already stereo and must stay stereo (stereo OH, stereo room or board 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 body or Mid without wrecking the image.
- You are not using it to "fix" unaligned melody+OH under room, or to replace a time-align edit on the matrix.
Decision table
| You notice… | First try | Why |
|---|---|---|
| Body thins when OH opens under melody/drone spots | Polarity; delay secondary; quieter secondary | Arrival-time fight |
| Hurdy-gurdy + bagpipe/fiddle harsh and hollow | Polarity; timing; hero Mid-safe path | Dual-path spot + companion |
| Fine in booth, thin on phone | Mono delivery bus; pull extras | Booth ≠ viewer fold |
| Stereo bed still cancels by band | PHIXER on that stereo bed | Residual spectral L/R fight |
| Mono hurdy-gurdy 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 bus yet.
- The fix is obviously polarity, delay, one hero image, or quieter secondary under melody/OH.
- You want PHIXER to make the hurdy-gurdy louder, wider, or "more wheel." Wrong job.
- The path is mono and the print problem is balance or EQ.
- See also when not to use PHIXER.
Quick path: Solo delivery bus in mono → polarity melody/drone spots vs OH/room → delay-align secondary → one hero image → quieter extras under hero → skip Haas/imagers → mono-check with full medieval/folk ensemble bed → PHIXER only for leftover stereo cancellation on a stereo bed → fold again for stream / studio print.
