Is there in the API beta release a script possible or avaiable which set output to left speaker, do a measure, set speaker to right do a measure ?. so it can work automatic and get 2 measures 1 left, 1 right
also usefull a script that do ever 7-10 sec a measure, so can put speaker in hand and...
maybe that it get higher on higher level happen becaue of treatment ? .because of more air pressure the foam did not absorb so much as with lower volume ?
at 84 db it is -26 db on 40 ms is 100 hz . and -52 db is 80 ms is 200 hz. is this not normal in higher levels on untreat rooms ?.o...
I have done tests and upload the mdat files. below you can see also on T30. below 100 hz the loudest measure have the shortest decay time. so my conclusion is, the lower volume measures have too few SNR. also the old T30 measure bring no better results. above 160 hz the loudest measure have the...
the results i get with T60m look as the noise floor is too high in the bass, because lots diffrent in compare to T30(from RT 60 page) in bass. I read about T60 T30 T20 here

The T60M in RT60 overlay choose did not show anything first, but i notice there need first press Generate in the RT60 decay page to see drawing in overlay. but it is great have high resolution. is it possible that this algo can also do a high resolution T30M ?. I think T60 is not so usefull in...
Do you mean in the rt 60 curve is no higher resolution as 1/3 possible ?.
I think the RT60 much better to see where to place foam and basstraps as the rt60 decay because it work with overlays. rt 60 deay not. the resolution i think should be at least 1/6 to see more easy when diffrent foam...
thanks, i test now and notice when i choose in rt60 decay 1/1 or 1/3 it switches to same value in RT 60. but RT 60 is not able to do more than 1/3 . is this limit enhance in future ?
wy does it show Classic: No Data on EDT T20 T30 ? .I have done estimate IR but it was 0,1 sample diffrence and generate minimum phase. happen on all measures i do. low or high level
Hello
when i have a value in SPL offset in a measure and choose add to data only then i can save the SPL offset. it is usefull when have diffrent speakers at same level to compare. when I want have original SPL how can i undo this ?. right click and choose in popup menu "undo SPL alligment" do...
I did not know how it change to 8 ms, but i test a older REW version, it do no such array out of bound error. I notice in new REW version from 20ms work ok.
I compare sine measure and FSAF measure with pink noise. in the default setting is a HP and LP filter add. I get with that filter bass and height loss for measure. I test without filter and it give very simular results to sine in FR. in RT60 i get not so high time at 50 hz . so seem can trust...
I do measure now from 2 hz instead 20 hz of soundbox loopback. its low level on a 16 bit UMC22 bwehringer USB from 2 hz let the excess group delay at 40 hz much more valid. for rt60 or rt60 decay this not help.
from 20 hz
this explain alot. I do soundcard cal then the phase get better, but excess phase go more minus. And when i measure a speaker i compare and i see now that in bass the excess phase go in that value lower as the excess phase from soundcard go lower. so better dont use excess phase for speaker...
then the question is how can get correct results in phase and RT 60 ?. if there is no exact way then i think it is more near the truth how much phase correction need when subtract in my case 67 degree when i want see real phase at 50 hz
I do always estimate IR delay and it shift 0,1 sample. do you think this is correct ? . the step response look strange is this because the sounddevice is very bad or is that normal look ? . it is a focusrite scarlett which is test good
the impulse response
