REW: eq match with two measurements instead of target

[llj098]

Hi,

I used REW to measure two different sm57' with REW.

Now I want to use the first one as my 'target', match another one's eq to the first one, I want the rew generate the eq match information for me.

Can I do this in REW?

Thanks

Yes you can export your preferred speaker response as txt and then load that text file as target curve in EQ window. But the right way is generating minimum phase versions of both speaker responses, vector average the minimum phase copies and "calculate target level" on that vector average in EQ window using a suitable target curve and use REW's auto EQ on that target with each speaker's min phase response to generate filters. Harmon curve is a good starting point.

Thanks a ton! I'll try it out!

using a suitable target curve and use REW's auto EQ on that target with **each** speaker's min phase response to generate filters.

Just to clarify, please:

Does that method presuppose being able to PEQ both L/R independently?

ie generating two sets, not one?

Thanks

Always two different sets of filters for L and R (but same target curve at the exact same level)

Harmon curve is a good starting point.

The SM57 is a microphone.

...I'm surprised there's a noticeable difference between two.

Don't try to make all of the "little wiggles" in the high frequencies match. Slightly different positioning, or things or people in different positions in the room can will affect how the direct & reflected soundwaves combine to create differences in the higher frequencies.
