The all-pass panel

Click ADVANCED in the Channel Controls to open a read-only panel describing exactly what PhaseLock is doing to the focused lane. It reads top-down: the time-domain correction first, then the phase-domain correction.

Applied time shift

The first row reports the lane’s total applied time shift in samples and milliseconds. Instead of a number you may see one of these states:

• Reference: this lane is the timing source and does not move.
• Original Timing: Time Alignment is off for this lane, so its natural timing is kept.
• Over Budget: the measured shift exceeds the 50 ms correction range, so the lane runs unprocessed.
• Not Measured: there is no analysis result for this lane yet.

All-pass filters

Below the time shift, the panel lists the all-pass filter sections the coherence fit placed on this lane, with a count such as 3 PLACED. Each row shows the section’s center frequency and Q.

Each section is one all-pass filter: it rotates phase around its center frequency and leaves the frequency magnitude unchanged. PhaseLock places a section only where its measurement predicts an improvement, so a lane that needs little correction gets few sections, and a lane that already combines well can get none.

The MAX cap

MAX sets the number of all-pass filters PhaseLock can use.

Choose 0 to use delay and polarity without all-pass filters. This is useful when your console does not have a compatible 360° all-pass filter.

If ADVANCED says RE-ANALYZE TO APPLY MAX 0, run Analyze again.

Tips

• The panel follows the focused lane. Click through the lanes with the panel open to compare what the fit did across the session.
• An empty panel on a lane with Improve Coherence enabled means the fit found nothing worth correcting beyond polarity. That is a valid result, not an error.
