Ukulele / Hawaiian ensemble multi-mic phase: close uke vs room, OH, and ensemble fold
Close mics on ukulele feel bright and present in the booth and on stage wedges. On club PA, studio mono fold, or livestream, body and strum attack often thin or cancel against room, OH, and ensemble paths that carry the same uke a few milliseconds later. That is usually polarity and arrival time between close and room/OH, plus a stereo uke 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 uke or ensemble beds before mono fold.

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 ukulele compressor, not a widener, and not a substitute for mic placement or mono audition of the stream or PA bus. Polarity and timing first; PHIXER after residual spectral fights.
What ukulele / Hawaiian ensemble phase failure sounds like
- Body and low strums thin on livestream. Close uke and room/OH share the same energy a few ms apart.
- Strum bite huge in booth, hollow on phone. Hard L/R uke layouts disappear when the platform folds.
- Ensemble OH fights close uke spots. Same content twice with different delay into the matrix.
- Club PA or session fold cancels midrange sparkle. Stereo bed never checked in mono before send.
- Fine in cans / wedges, broken for remote viewers. Same destinations as club / DJ / PA, live FOH / foldback, TikTok / Reels.
Fast mono audition (about 60 seconds)
- Solo the stream / PA / mix bus (not only booth headphones). Flip a utility to mono.
- A/B close uke muted vs open under room/OH/ensemble. Note what disappears: body, low strums, sparkle, attack.
- Solo pairs: close vs OH, uke vs room, stereo uke bed vs mono fold.
- Check correlation on the delivery bus, then with uke muted vs full.
Order of operations (before spectral phase rotation)
1. Polarity between close uke and room / OH / ensemble
Flip close vs OH, or uke vs room, when body or low strums return immediately. Guide: polarity vs phase. Related: acoustic guitar multi-mic, bluegrass / string-band.
2. Small delay align close to the room / OH image
Close mics often arrive earlier than room or OH. A few samples of delay on the close (or nudge to the hero ensemble image) often restores body better than any widener.
3. One hero uke / ensemble image to the stream or PA bus
Do not send close, OH, room, and ensemble spots all hot into the livestream or PA. Pick a hero image (often a focused close+OH blend or the ensemble pair), keep extras muted or low. Parallel stacks are classic hollow-body on phone fold. Related: choir / ensemble.
4. Prefer hero room/OH as the body; quieter color close
The close should color string detail and proximity, not replace the hero image for the stream mix. If the close sits at full level under a loud OH, mono fold almost always hollows body. Pull the close first.
5. Skip wideners and Haas on uke beds before fold
Short-delay width and stereo imagers make booth headphones huge and phones hollow. Keep critical low end and body centered for stream and PA.
6. Only then audition residual L/R spectral fights
If a stereo uke or ensemble 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 |
|---|---|---|
| Close uke + room / OH | Body / low strums cancel on stream | Polarity; delay close; quieter close |
| Uke spots + ensemble OH | Sparkle disappears on phone | Polarity + delay; hero image |
| Close + stage bleed | Attack combs or thins | Bleed control; polarity; one hero |
| Stereo uke pair hard L/R | Huge in cans, gone on phone | Center critical lows; simplify width |
| FOH / matrix → OBS / PA | Fine in booth, hollow for crowd | live FOH / club PA |
Studio / club / livestream checklist (to send)
1. Label close vs OH vs room vs ensemble paths
Name close uke, OH, room, and ensemble spots so operators know what hits the livestream or PA. Ambiguous stacks get left open and comb on fold.
2. Mono-check delivery bus alone, then with full uke
Solo body and low strums in mono. Then open sparkle and attack in mono. Note fights between close color and hero body.
3. Watch phone, social, and PA destinations
Most remote viewers and many dancers hear mono or near-mono. Guides: live FOH, club / PA, TikTok / Reels.
4. Optional null / mono workflow before show

When PHIXER belongs on uke-related stereo
- The material is already stereo and must stay stereo (stereo uke pair, stereo room/ensemble 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 sparkle without wrecking the image.
- You are not using it to "fix" unaligned close+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 close | Polarity; delay close; quieter close | Arrival-time fight |
| Sparkle + room collapse on stream | Hero image; polarity; delay | Stacked identical content |
| Fine in booth, thin on phone | Mono delivery bus; pull close | Booth ≠ viewer fold |
| Stereo uke still cancels by band | PHIXER on that stereo bed | Residual spectral L/R fight |
| Mono uke 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 / PA / mix bus yet.
- The fix is obviously polarity, delay, one hero uke image, or quieter close under room/OH.
- You want PHIXER to make the uke louder, wider, or "more Hawaiian." 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 close vs room/OH/ensemble → delay-align close → one hero uke/ensemble image → quieter close under hero → skip Haas/imagers → mono-check with full uke → PHIXER only for leftover stereo cancellation on a uke bed → fold again for stream / PA / club send.
