Linear Phase EQ - Room Correction: Part 1 - REW 

Thank you, I'm glad to hear you liked it! After I'm done with this room EQ stuff, I'll be moving over to Active Speaker guides (the way I do it at least), so hopefully that'll be to your taste even more so!

@Regular Guy Audio Me too! 😅

No problem!

Hoping to release it soon! Wanted to get that linear phase explanation video out first though!

Thanks Justin!

Sorry it took me so long to get back to you. First of all, just so you know, parametric EQ will likely only be minimum phase (but in your options, if you see somewhere that says minimum phase, click it anyways since it may be a drop-down to select linear or mixed phase - if that's what you want that is). Other than that, unfortunately I am not experienced with Hypex amps, but what should always work is entering the values manually. If you go into REW EQ and choose generic instead of RePhase, you can then go into the EQ filter banks at the top and depending on how many bands of EQ you have (8, 10, 12, 16 are common values but you may have a different amount available) you can set more by selecting them from None to Peaking, or set less by selecting Peaking to None. Then carry on generating the EQ filters as per usual, go back into the filter banks and then you can use those values to fill out the parametric EQ banks in your Hypex amp manually. If using minimum phase EQ, I recommend taking an RMS average of all your speakers and applying the same EQ to all of them so that when they play at the same time you don't have phasing problems.

Hello, improve phase in terms of what exactly sorry? In terms of correcting a passive speaker's phase from its crossover components, or are you referring to something else?

Be careful with too many taps at low frequencies as that actually could introduce some noticeable time domain artifacts if corrections are too sharp, especially boosts. I would recommend going with something like Multi Sub Optimiser instead of you have more than one, as that actually uses the phase change of minimum phase filters to control how to subs interact to give a smoother distribution of bass over the space, should be a lot easier to implement too!

Thanks

Do you mean you want to apply it to an individual audio file (one with music on for example)?

If so, you can use a VST plug-in like the one on convolver.sourceforge.net/vst.html, and use it in a DAW, or since it's a VST2 type plugin, you can also use it in Davinci Resolve which is a free video editor, that can also just be used for audio editing. Hope this helps 👍

I know, it was an output error from my video editor output, I wasn't aware it fed mono audio into stereo single channel. So sorry about that, glad you liked it otherwise. In all videos since this one I have fixed the issue
