RTA Settings

[Alpi]

Sorry for all the questions, and I am reading the user manual, but for some things, there are so many settings that it's hard to know whether the default settings specified by REW are suitable for the measurement.

I want to measure my speakers with a waved measurement in the seating area MLP and then correct the frequency response with a DSP. However, there are several options in the RTA window settings, and I don't know which one is the right one.
I have a photo of the various setting options here. Can you tell me if they are the right ones for my measurement?
I am using a “pink periodic full range” source signal.

My second question: Which measurement do you prefer for equalizing the speakers in the room?
One measurement at the MLP.
Eight measurements around the MLP.
Waved measurement with RTA.

Thank you.

There's a thread on MMM here, and quite a few YouTube videos, such as these:

Charles wrote an AES paper on MMM.

I think your config is a-ok, if you want you can use the pink random noise generator, it really doesn't make much of a difference from periodic noise and is a bit more pleasant to listen to.

For room EQ, moving mic RTA method is quick, easy, and can get you 98% of the way there. It doesn't provide any detailed information on resonant modes for RT60 or waterfall analysis, but some info can certainly be inferred by the shape of the measured response. So for that last 2%, you should also complete some individual sweep measurements.

Thanks John for the Videos!

I do the same with multi-point measurement. The average frequency response of eight measurements around the MLP is very similar to the waved measurements.
In the bass range from 10 to 100 Hz, I look at the frequency response, waterfall, etc. with a single-point measurement.
Of course, I also use a single measurement to time-align the LS with the impulse response.
