Room correction

[canard]

It would be great if they they give us a choice like the one from mini dsp. Butterworth, linkwitz Riley and few others with a graph that shows the slope.

It was suggested from the first days of the arrival of the ultra and the sub function
classically... orders and types

Triple pass has improvement over single pass before. Rc is becoming mature to a point it may even compare to gold standard Dirac. Wiim is not done tweaking rc they have more feature to add soon.

Is triple pass really better if the microphone isn't moved between passes . Seems pointless to me. The benefit from multiple measurements is from moving the mic into different positions to avoid a result that only sounds correct in one listening position. WiiM clearly didn't understand this. As is often the case they listen but don't hear. People asking for multiple measurements definitely did not intend those measurements to be from the same place

I'm starting to lose patience.
Wiim adds sweeps, L/R mode and various other things to RC. But all measurements are based on inaccurate phone microphones, and you can't install calibration files to external ones. All measurements are inaccurate anyway. There's no information from Wiim whether they'll do it or not. I've been using HouseCurve and Dayton mics for this reason for some time with very good results and I've stopped using RC Wiim completely.
I'll probably say goodbye to Wiim and buy Eversolo DMP-A6, because it also has PEQ.

You're complaining of a free feature that wasn't included with the original product. They've improved things, and still whining?

If you want dedicated well polished room EQ, buy something with Dirac, Anthem ARC, room perfect, or a trinnov.

It's using a calibrated mic, and from my file it's not that bad, it's pretty flat (I can see the mic correction curve in REW)

Calibration files will be coming. All measurements are not based on inaccurate phone microphones if you choose to use an external mic. The UMIK-1 is very flat anyway so it won't make a massive difference. What does make a massive difference is the way phones perform with mics like the iMM6 TRRS version. USB mics should be OK but from cal files posted on here the Dayton Audio USB mics definitely need cal files at low frequencies.

It compensates for noisy environments. Not everybody lives in a home where all noise is within one’s control,

Thank you for the positive signal. I didn't see this post. So there is hope

Well, I mean, you can move the mic around between the sweeps. You are not obliged to use the same spot…

At the end, it is all about compromise anyway - as everything in life!
If you measure on several spots, it will be better on every spot you measured, but probably less good, than in that one place you measured first!

I suppose it would do that. That isn't what was wanted by the people asking for multiple measurements though.

 

[rccarguy]

yes it should wait, prompt you to move mic to another position, ie I'd move it in a 30cmx30 area where my head would be

Lots of thoughts about methods here

Moving mic vs. averaged vs. single point measurements - which is better?

AFAIK there are three ways we can measure room response for loudspeakers: - Maximum Length Sequence (MLS), Exponential Sine Sweep (ESS) or single point sweep: The mic is set up at the listening position, and a single sweep is taken. - Averaged: The mic is set up at various points around the...

The triple pass may average the 3 sweeps on single location where single listener sit but as far other rc brand where they do multiple sweep on various location because it was home theater for multiple viewers.

Listen to the music, not the measurements!

The point of rc was there an improvement over when rc is off? I agree many users spent great deal of time running rc instead of listening. As result their wiim became just a toy playing rc and not actually listening to enjoy their music. What are they want to get the same ruler flat you get on audio precision? The 1/3 smoothing can make those response relatively flat over zig zag 1/12.

It's not difficult changing from on to off. I've also created a "cut only no boost" profile for the both sets of speakers.

Tried RC once. Sounded worse than no EQ at all. Maybe my system is "too good" to need any corrections or maybe it's just my hearing?

When it's done calculations, modify it, remove any positive values. Then save that preset.

But yeah my systems sound good without RC (for the speakers) RC just sounds different. For subwoofers room correction is a must if it's all over the place. I think with sealed subs response is generally flatter so you might get away without subwoofer EQ.

Results of RC depends entirely on the settings you choose and the accuracy of the mic you use. It's easy to get it wrong.

Also depends on the auto EQ system. The auto EQ in my processor (Tonewinner at300) sounds utter garbage, it applies multiple +12dB boosts, and makes my speakers sound AWFUL. It has a calibrated mic with file also.

You can enter in values manually like the Wiim's, but the Wiim has a few extra options
