11 Best Phase Alignment VST Plugins 2025 (+ FREE Plugins)

Let’s talk about some of the best phase alignment tools/plugins you can use to make your mixes sound right!

Phase alignment might be one of the least glamorous topics in audio, but it’s quietly responsible for half the clarity, punch, and depth in any mix. When multiple mics or tracks don’t line up just right, even the best recordings can lose their power.

That’s why I’ve built a small arsenal of phase-alignment tools that save me from endless nudging, flipping polarity, and second-guessing my ears.

Each of these plugins approaches phase correction differently, but all share one goal – making your mix sound tighter, fuller, and more natural.

With that being said, let’s jump righ in:

1.  Sound Radix Auto-Align Post 2

When I’m cleaning up dialogue from multiple lavs and booms, I don’t want to fight phase issues for hours. That’s where Auto-Align Post 2 steps in like a quiet hero. It automatically lines up your mics in real time, so you can focus on mixing performance instead of fixing timing.

I’ve used it on busy multi-mic sessions, and it instantly tightens everything up – no weird comb-filtering, no guesswork, just smooth, natural dialogue that sits perfectly in the mix. The new ARA2 integration makes it even easier inside Pro Tools and Resolve, so it feels like part of your editing flow instead of another step to think about.

• Automatic mic alignment – Instantly syncs multiple mics within ±100ms, removing phase issues and saving hours of manual editing
• Adaptive spectral phase correction – Preserves tonal balance and clarity, fixing subtle phase shifts that occur across different frequencies
• Real-time ARA2 integration – Works seamlessly inside Pro Tools, DaVinci Resolve, and other ARA-compatible editors, streamlining your post workflow
• Optimized CPU performance

2. Waves Sub Align

Sub Align fixes that instantly without needing to dig into the venue’s PA settings. You just drop it on your master bus, “move” the subs virtually until everything locks in, and suddenly the mix tightens up like magic. The kick and bass sit right where they should, with none of that mushy overlap that kills clarity in small rooms..

It’s the kind of tool that makes you wonder how you ever gigged without it, especially when you’re stuck with house systems you can’t touch.

• Virtual sub movement – Adjusts sub timing in milliseconds, feet, or meters to lock in perfect phase alignment between subs and tops
• Crossover frequency matching – Lets you tune Sub Align to match the PA’s internal crossover, keeping low-end frequencies routed correctly for tighter sound
• Independent stereo control – Align or unlink left and right channels to handle uneven venue setups or asymmetrical speaker placements.

3. SSL X-Phase

Phase problems aren’t always obvious until your mix starts losing punch or width. Sometimes it’s just one mic out of place, throwing everything off. That’s where SSL’s X-Phase quietly earns its spot in the toolkit. It lets you surgically shift phase at a specific frequency without touching the signal’s gain, which is perfect for cleaning up tricky mic setups like drum overheads and close mics.

I like how precise it feels – you can zero in on the offending frequency, tweak the Q, and instantly hear the stereo image snap back into focus. It’s not a flashy plugin, but when you need a clean, phase-accurate mix, it’s the kind of control that actually matters

• Frequency-targeted control – Shift phase at a single frequency with total precision, no tone change, no EQ trickery.
• Delay section for broad fixes – When things are out of sync by more than a few samples, the built-in delay can nudge entire tracks into alignment. You can set it in milliseconds, samples, or even physical distance, which makes it super handy when matching mics placed far apart.
• Independent L/R operation – Work on one side or link both for stereo balance. Quick and simple.
• Instant A/B comparison 

4. FLUX Evo In

Phase can make or break a mix, especially when you’re blending multiple mics on one source. EVO In handles that with a super clean, zero-latency phase rotation that feels like physically moving the mic into the perfect spot. It’s subtle, but you immediately hear the focus tighten up and the low end fall into place.

Whether you’re tracking drums or dialing in live sound, it just makes everything sit naturally without overcomplicating the process.

• Linear phase rotation – Adjusts phase across the full spectrum, just like repositioning a mic in real space.
• Zero latency
• Studio and stage ready – Works equally well on drums, vocals, or any multi-mic setup.
• Flux proprietary algorithm – Unique design ensures transparent correction without coloring the tone.

5. Waves InPhase

Mixing multi-miked instruments always comes with that one challenge that sneaks up on you: phase. It’s the reason a perfect snare recording suddenly sounds thin or why your bass DI and amp blend doesn’t quite hit right. InPhase is one of those plugins that just fixes it without the guesswork.

You can nudge waveforms visually, adjust phase at specific frequencies, or even use sidechain alignment to lock multiple tracks together. I’ve dropped it on drum overheads, bass tracks, even parallel busses, and every time it brings the sound back into focus. It’s that “why does this sound instantly better?” kind of tool that quietly saves your mix.

• Waveform alignment – Grab, drag, done. You see the problem and fix it by eye
• All-pass phase filters – Two precision filters give you frequency-specific control so you can clean up phase where it counts, without dulling the highs or shifting the entire track.
• Sidechain magic – Use one track as a reference and lock others to it. I use it constantly for aligning drum overheads with kick and snare mics.
• Delay-only mode – For those times when the issue isn’t phase rotation but pure timing offset – quick, accurate, painless. Mono, stereo, live – Works everywhere, from complex studio sessions to fast-paced stage setups.
• Real-time feedback

6. Melda MAutoAlign

Recording with multiple mics can sound huge—or completely lifeless if phase gets in the way. Most of us have spent way too long nudging waveforms and flipping polarity switches to find that sweet spot. MAutoAlign just skips all that pain.

Drop it on your tracks, hit analyze, and it automatically finds the perfect phase and delay relationships between every mic. The first time I used it on a drum recording, the difference was unreal: the low end snapped back, transients hit harder, and the mix suddenly felt glued together. It’s transparent, automatic, and ridiculously fast at doing something we all hate doing manually.

• One-click phase alignment – Add it to each mic track and let it do the math. You press one button, it sorts the timing, and you move on
• Automatic polarity detection – No guessing, no flipping switches – it identifies and corrects polarity conflicts across all tracks on its own
• Spectral phase compensation – Goes way beyond time alignment. It can correct phase for every frequency band individually, fixing complex phase shifts caused by mic position, EQ, or processing

7. NUGEN Audio Aligner

If you’ve ever recorded with multiple mics and felt your track sounded thin for no obvious reason, you’ve probably been hit by phase misalignment. That’s where Nugen Audio Aligner quietly fixes everything in seconds.

It’s just great for drum setups, guitars, or any multi-mic source where “almost aligned” isn’t good enough!

• Automatic phase & polarity correction – It detects and fixes timing and polarity issues instantly, no setup needed
• Lightning-fast workflow – One click and your tracks lock in. Seriously, it’s that quick.
• Subtle but powerful – Even small adjustments can completely change how solid your mix feels
• Perfect for multi-mic sessions – Works beautifully on drums, guitars, and vocals where distance causes phase drift
• Zero learning curve

8. Eventide Precision Time Align

Precision Time Align lets you slide audio forward or backward down to a fraction of a single sample, locking everything together tighter than manual editing ever could. Once aligned, the hollow comb-filtered tone disappears and the punch comes back instantly. It’s one of those surgical tools that’s not glamorous, but absolutely essential when detail matters.

• Sub-sample accuracy – Shift tracks by up to 1/64th of a sample for exact alignment between mics
• Coarse and fine controls – Dial in big timing moves or micro-adjust with surgical precision
• Phase invert option – Instantly flips polarity to fix mirror-image phasing issues
• Negative delay capability – Push tracks slightly forward in time relative to others for perfect synchronization.
• Four calibration modes – Multiple alignment methods so you can match phase your way, whether visual or by ear
• Time Delay companion plugin – Included for DAWs without built-in delay compensation.
• Real engineering tool – When “close enough” isn’t enough, this plugin locks it in perfectly.

9. Sound Radix Pi

Sometimes your mix feels right tonally but still collapses when the kick and bass hit together – that hollow “where’d the low end go?” kind of thing.

That’s exactly what Pi was built to fix. It automatically manages the phase interactions between every track in your session, constantly adjusting in real time so frequencies stop fighting and start working together. I like using it as the last insert across key mix buses or even every track – it just makes the mix sound fuller and more stable without any weird coloration. It’s like invisible glue, but for phase instead of compression.

• Dynamic phase optimization – Continuously analyzes your mix and adjusts each track’s phase so frequencies complement instead of cancel each other. Multi-track awareness – Every instance of Pi communicates with others, keeping the whole session in sync automatically
• Low-frequency mode – Focuses on the sub and bass range to stop kick/bass clashes that make mixes feel hollow.
• Grouping system – Up to 64 groups for controlling related instruments or multi-mic setups as one phase-aware unit. Multi-band phase meter – Lets you see exactly how phase correlation changes across different frequency ranges.
• No routing or sidechain setup – Just drop it in and it handles communication between instances on its own. Real mix enhancement – Restores low-end depth, stereo width, and mono compatibility without EQ or compression

10. RSPhaseShifter

You know that moment when two tracks should blend perfectly, but something feels off – like the tone just thins out no matter how you EQ it?

That’s not your ears playing tricks on you, that’s phase fighting back. This is where RSPhaseShifter steps in and does what most phase tools can’t: it gives you full, analog-style phase rotation that actually sounds musical. It’s based on Roger Schult’s original hardware, rebuilt with modern precision, so you can sweep through phase angles until everything locks in naturally.

Whether it’s tightening a DI and amp, fixing drum bleed, or giving stereo guitars more body, it lets you fine-tune your sound by ear, not by math.

• True analog behavior – Modeled after Roger Schult’s W2324 hardware, bringing the same smooth, continuous phase shift to your DAW
• Full 360° rotation – Sweep phase across the entire range and find that perfect tonal balance point between layers.
• Mono or stereo flexibilityy – Perfect for pairing multiple mic sources, stereo guitars, or even sub alignment in a mix

11. Forward Audio SampleDelay (FREE)

If you’ve ever stacked a few mics on a drum kit or guitar cab and heard that weird hollow sound creeping in, you know how frustrating phase alignment can be. Most of the time, you just need something quick and simple that gets the job done without a whole setup routine. That’s exactly where faSampleDelay shines.

It’s lightweight, dead simple, and super responsive, perfect for those quick micro-adjustments that make a track suddenly feel right. I’ve used it countless times on kick and overheads, or guitar mics just slightly out of sync, and every time it tightens things up instantly.

• Sample-accurate delay control – Shift audio up to 100,000 samples with full precision, giving you total control over phase and timing alignment.
• Fully scalable interface – Clean, resizable GUI that makes fast phase tweaking painless whether you’re on a laptop or a 4K monitor.
