Default Phase Presets Tip

Please disregard if this has been discussed before.

I stumbled on a convenient way to adjust phase.

Reserve 4 banks for phase.
  • Preset the 1st bank for "flat 2/3 oct".
  • Preset the 2nd bank for "flat 1/3 oct low freq"
  • Preset the 3rd bank for "flat 1/3 oct mid freq"
  • Preset the 4th bank for "flat 1/3 oct high freq"

Use the 1st bank to enter course adjustments.

Use banks [2-4] to layer fine adjustments on top of the course adjustments.

Default Phase Offset

Hello,

If I were to equalize all drivers seperately, on seperate channels with seperate impulse response convolutions, how would I add a phase offset of +360 to the tweeters to compensate for the lagging behind of the woofers due to the LR4 crossover?
From what I understand the "Filters Linearization" tab is of no use here, because im using seperate channels.


Thank in advance you for your help.

Are you trying to build a minimum-phase crossover, or a linear-phase one?

Luckily phase tracking is much easier to get right when building an acoustical linear-phase crossover compared to a minimal-phase one.
Try following these steps: rePhase, a loudspeaker phase linearization, EQ and FIR filtering tool

Not sure if it didn't work for anyone else, but here's another link to try if it didn't:

It didn't on mine. I think it's because your link has a reference to the page number, and the page number doesn't match up with my account settings (it's like... page 68? that thread only goes up to page 61 for me) whereas my link seems to be page-agnostic.

I think I know what happened... you probably grabbed the URL after you clicked through your target link. This is the URL I get after I click my link:

rePhase, a loudspeaker phase linearization, EQ and FIR filtering tool

Same format as your link, which is different from the page-agnostic link that I directly captured from the #xxx link in the top-right of the post:

rePhase, a loudspeaker phase linearization, EQ and FIR filtering tool

It makes a difference, apparently.
