PHIXER for Snare Top/Bottom: multi-mic phase that keeps body on mono fold
Top and bottom snare mics can sound huge in headphones. On phone playback, Bluetooth, club PA mono, or livestream fold, crack stays and body dips. Polarity and a few samples of timing come first. Free phase-repair helps after residual L/R fights remain on a stereo snare or kit bed you must keep stereo. It is not a snare replacer, and it does not replace a true mono listen on the bus.

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 polarity button, not a delay matcher, not a widener, and not a substitute for mic placement. Use it after hygiene, when residual spectral cancellation remains on a stereo bed you must keep stereo.
Three snare failure modes this page covers
- Top vs bottom snare phase. Fine in cans; hollow body on phone or club fold while crack stays. Deep guide: Snare top/bottom phase.
- Drums / tom multi-mic cousin. Same fold shape on tom fills and kit beds. Guide: Tom multi-mic phase and PHIXER for Tom Fills.
- Kick cousin: in vs out. Same two-path fight on the kick. Use-case: PHIXER for Kick In/Out.
Fast snare mono audition (about 60 seconds)
- Sum L+R on the snare or drum bus (or monitor controller mono). Listen to body with top and bottom open.
- A/B stereo vs mono across a backbeat and a fill. Note what disappears: shell body, wire buzz weight, or attack that was actually cancellation.
- Mute bottom briefly. Flip Ø on the bottom (or the path that was flipped by habit). Keep the flip that returns body without killing the crack.
- Nudge a few samples of attack timing before chasing plugins. Confirm on a phone speaker, then again after bus EQ / compressor / saturation.
Honest order of fixes (before spectral phase rotation)
1. True mono listen on the full snare
Hard L+R sum or monitor mono with top and bottom open. Habit: snare top/bottom checklist and mono check workflow.
2. One hero for body
Prefer one path for weight (often the top) and let the bottom add buzz / wires without fighting Mid on every hit.
3. Polarity before more processing
Flip Ø on bottom (or the suspect path) while mono. Keep the flip that returns body. Guide: polarity vs phase.
4. Attack timing before spectral tools
Nudge a few samples or ms so transient peaks agree across top and bottom. Often enough on its own on phones and clubs.
5. Skip when intentional thin snare is the point
Some mixes deliberately thin in mono for crack-only snares. Honesty list: When not to use PHIXER.
6. Only then audition residual L/R spectral fights
If a stereo snare or kit 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. Watch the YouTube tutorial and the mono demo.
Snare path types
| Setup | Common mono failure | First fix |
|---|---|---|
| Top + bottom close | Body dips when summed | Polarity + timing; mono listen |
| Top + bottom + OH bleed | Crack stays, shell disappears | One hero body; flip Ø |
| Stereo kit bus + snare spots | Backbeat scoops on phone fold | Drums / tom multi-mic |
| Kick in/out under the snare | Sub fights snare body | Kick in/out guide |
| Tom fills around the snare | Fill + snare both hollow | Tom fills use-case |
Drums, kick, and toms cousins (short version)
- Tom multi-mic and kit beds share the same fold shape as top vs bottom. Full write-up: Tom multi-mic phase.
- Kick in vs out hollows the same way. Full write-up: PHIXER for Kick In/Out.
- Tom fills around the snare need the same mono habit. Full write-up: PHIXER for Tom Fills.
- Polarity and timing still come first on every cousin. Spectral tools after residual L/R fights only.
When not to reach for PHIXER
- Wrong polarity on bottom (or top) snare (flip Ø first).
- Obvious attack misalignment between top and bottom (nudge first).
- You only need one hero mic or a mono-safe print of the snare.
- Intentional thin snare that is meant to stay crack-only in mono.
- Honesty list: When not to use PHIXER.
