Your measurements suggest that the slatted panel is too loose on the wall, causing it to vibrate and resulting in a decay time increase and frequency boost at 100-130 hz, which is also visible in the detailed room reverberation.see here . and here are also see the settings so you can see a more...

this are the impulse of room above in my posts.I use right speaker because this is the speaker with the longer rt60 decay. left speaker look better the desktop have many influence so the higher end solution on desktop is only this :jump: maybe thinner foam work too, because it now damp a...

can you please show RT60 decay from REW ?. the other is much too unprecise, maybe show too much or too few. normaly the more less the frequency go the longer reverb time you get. keep in mind from floor to ceiling in your room is 2,7 meter. soundspeed is ~343 meter per sec. this mean with a...

Problem for me was in my room because on frequency between 60-250 hz i get strange feeling in ear as speaker is out of phase. only with my current foam i can say it is 100% gone and i can very long hear music and much more songs sound great now, also youtube songs which only have 128 kbits ...

It is very good that the generator frequency can now increase in notesteps. when i do this the lower volume of the 600 hz dip see in measure, can only very slightly hear. because lower frequency is 587 then next is 622. Because music use mostly step frequencies so it is maybe usefull to have a...

so it is correct that the menu "RMS+ phase average" is diffrent to "(A+B) /2" ?. so for what i want i then should only RMS + phase average see the diffrence between them

RMS average is not in the new arithmetric button. I find it on old place "all SPL" and RMS + phase average. What is diffrence between RMS + phase average and (A+B) / 2 in aerithmetic menu ? the RMS + phase average work as i expect at 600 hz. it is in middle of left and right speaker. Result is...

I see at 605 hz is phase really more diffrent as on other frequency L have 216 R 110 and the AB average 136 . the average seem have more priority for phase can see. estimate IR delay shift 1,8 samples both and have no changes only on much higher freq Wy this happen at the 200 hz and then work, i...

i do a test project, save only 2 measures, restart REW and the results are diffrent. at 200 hz ok now, but at 600 hz now not ok

The arithmetic not work when use ERB smoothing or need i change a setting ?. not 100% sure in older REW i use it and i see not such problem 1/3 smooth results or 1/12 smooth results look good, but ERB not also later change the smooth of the result does not help . i also try out other calc but...

currently it is a version of ISO 3382-3 from 2022 . original ISO 3382 is very old, i dont know what they change in newer version, maybe the calculation ? https://www.din.de/de/mitwirken/normenausschuesse/nals/veroeffentlichungen/wdc-beuth:din21:345469066/toc-3338603/download and here is the...

Hi I have measure so SNR is mostly over 60 db. Can see in screenshot the calculated T60 values are more or less diffrent to real T60 values measured. maybe when SNR is over 60 db can use the real value that is in measurement at -60 db ? you can see here how diffrent the real to calculate RT60...

see in the screenshot. in the frst screenshot the 0 is draw more left as in the second screenshot. also see the cursor i set to 69.8 hz. it have in compare to text above "rew is free software" can see difftrent position. wy is the start diffrent ?. to compare it is usefull when in all measures...

Hi I do sequential mode measures of left and right speaker. in the rt60 display the 0 start i guess is 10 ms diffrent in the graph. Estimate IR delay detect, 0,3 samples when i do that on all, and when i let correct it do not help. 3 ms is 1 meter diffrent. so this large diffrence in 0 can not...

ok, i thought was forget to sync.I see the popup menu have in measure selections "clear selections", and "toggle selections" entry. so i use this now
