Automatic phase alignment for fuller, more coherent multi-mic audio.

PhaseLock analyzes related microphones and improves how they combine with frequency-dependent phase correction, automatic polarity control, and optional time alignment. Keep the natural timing of rooms and distant mics, or align arrivals when the job calls for it.

It added extra weight to both kick and snare while sounding more natural than Auto-Align® and definitely smoother transients and bigger low end than the raw recordings.
Jack P. Mix engineer

Phase coherence and time alignment are two separate things.
PhaseLock does both.

PhaseLock’s Phase Coherence control automatically sets all-pass filters so the tracks sum more coherently without moving them in time. Time Alignment lines up transients automatically when you want it. Use either one on its own, or combine both.

  1. 01 Choose a reference track
  2. 02 Turn Time Alignment on or off as needed
  3. 03 Phase Coherence is corrected automatically across all tracks
“I LOVE that this is tackling the phase coherence issue with the option to not nudge the audio around. Brilliant. Nudging the audio around has always felt like 1 step forward and two steps back. Always very heavy handed. But this feels like only a step forward! Big win here!!”
Zach F. Mix engineer

Tighter drums, stronger low end

Correct the comb filtering between close mics and overheads that thins out the kit, so it keeps its low end and holds together in mono.

Match lav and boom tracks

Fix the hollow sound of a lav summed with a boom. Add PhaseLock to the related tracks, choose a reference, and analyze a representative section.

Under the hood

PhaseLock rotates the phase of each track so the mics add instead of cancel. It does this with first- and second-order all-pass filters, which change phase without applying EQ or changing level.

Can PhaseLock preserve each mic's natural timing?

Yes. Time alignment is optional, and you choose the reference track.

How is this different from Auto Align?

Imagine if Auto Align cared more about natural sounding phase relationships, and not just time alignment. More here.

Can I use PhaseLock for live audio?

Yes. Phase Coherence adds no latency, so you can correct phase coherence in a live setup through a compatible plugin host. Time Alignment also works live, but it introduces the delay required to align the signals.

Which formats and systems are supported?

PhaseLock is available in VST3 and AAX formats for Windows, and VST3, AU, and AAX formats for macOS.

What happens if I cancel the monthly plan?

PhaseLock keeps working through the end of your current billing period.
