Harrison Mixbus / Ardour polarity vs PHIXER continuous rotation for mono-safe low end
Harrison Mixbus and Ardour still give you strip polarity invert, mixer / monitor mono fold, console-style bus hygiene, and small delay align before export. That is the stock first pass (and a strong Linux-friendly path with VST3/CLAP). Continuous stereo phase is a different job: leftover L/R fights that still cancel by band after polarity, timing, and mono fold. This page is the Mixbus / Ardour comparison.

PHIXER is free stereo phase-repair (VST3/CLAP/AU · Win/Mac/Linux). Amount / From / To rotate problem bands so mono fold keeps low end without flattening stereo. On Mixbus / Ardour Linux, load VST3 or CLAP (AU is macOS-only). It is not a replacement for strip polarity invert, mixer mono fold, or delay align. Polarity and timing first.
What Mixbus / Ardour already does
Strip polarity invert
A 180° flip on one path. First fix for dual-mic, DI+amp, or a parallel send that fights the dry path. If body returns immediately, stop. You do not need spectral rotation.
Mixer / monitor mono fold
Headphones and console-style buses can hide cancel. Engage mixer mono or a dedicated mono Utility on the audition / master path. Toggle it. That is the Mixbus / Ardour mono-check. Broader habits: Mixbus mono · Ardour mono.
Delay align / sample nudge
Small delay on one path often fixes timing fights before any continuous rotator. Correlation meters can look safe while master mono still thins Mid. Headphones still lie.
Where polarity stops
- Cancel is band-specific. Lows gone, mids still wide. A single 180° flip is too blunt. Stereo width can look fine while mono fold still hollows bass.
- The part must stay stereo. A stereo sample, return, or console bus that you cannot collapse to mono without losing the image.
- Polarity + delay already tried. Invert and delay nudge did not restore body. Residual L/R spectral fight remains.

Mixbus / Ardour decision table
| You notice… | First try (stock) | Then |
|---|---|---|
| Body returns when you invert polarity on one strip | Keep the invert. Done. | Do not reach for PHIXER. |
| Stereo OK, mixer mono still thins | Trust mono fold over headphones | Re-check master / monitor mono before export. |
| Stereo bass still hollows by band after polarity + delay | Null-test / mono honesty | PHIXER Amount / From / To on that stereo bed (VST3/CLAP on Linux). |
| Stereo width / Haas huge in cans | Bypass the widener | Mono fold honesty. Not a repair job. |
| Mono sample alone is dull | Tone / EQ / sample choice | Not an L/R phase job. |
Mixbus / Ardour habit (about 90 seconds)
- Mixer mono or monitor mono Utility. Note what disappears (kick body, bass Mid, vocal chest).
- On dual paths: polarity invert on one strip. Re-check mono.
- If timing is the problem, delay nudge. Re-check.
- If a stereo bed still cancels by band, audition PHIXER VST3/CLAP. A/B with the plugin bypassed, still in mono.
When PHIXER helps in Mixbus / Ardour
- The clip or bus is already stereo and must stay stereo.
- Polarity, delay align, and mixer mono hygiene are cleaned up.
- You can hear clearer mono body with PHIXER engaged and the image still usable in stereo.
- You are not using it to replace polarity invert or to "fix" stereo-width / Haas width.
- On Linux you confirmed VST3 or CLAP scan (not AU).
When NOT to use PHIXER here
- You have not mixer-mono-folded yet.
- Polarity or delay already restored the fold.
- You want PHIXER as a widener or a polarity clone. Wrong job.
- The path is mono and the print problem is balance or EQ.
Quick path: Mixbus / Ardour mixer mono → polarity on dual paths → delay nudge → PHIXER only for leftover continuous L/R fights → mixer mono again before export.
