i notice when use othe color sheme. only the dottet line is steped. On other settings wavelet th dottet line is not stepped, but i think it is not correct what can see

did you hear no diffrence in the 4 ms test i upload ?. this huge phase problems bigger speakers have, shift the harmonics and so the waveform inside a bass instrument. bass sound driffent and lush when phase between harmonics differ resonances is a big problem when speaker get larger...

maybe the steps are create from FFT size or window size 16384 say the AI because this fit to 15 ms steps. here a zoom . energy peak time is much more stable as group delay. i only ask if it can maybe easy reduce with diffrent window size or reduce fft size ? this are 2 mm measures, and on both...

The peak energy time work mostly in steps of 0, 15 ms , 31 ms, 46 ms. is it possible that this steps can reduce easy to 4 or 8 ms ? EDIT: The group delay have better precision but this is on hearing place so much fluctuating. so energy peak time look more realistic here is a audio test that can...

I try the decay graph with newest beta, only when i reduce rise time to 10 ms it show usefull decay. . here can download the headphone measures. https://www.audiosciencereview.com/forum/index.php?threads/floyd-tooles-toronto-aes-presentation-from-october-28-2025.67011/page-2#post-2650886 I use...

which is the setting for highest resolution in spectrogram slices. ? https://www.audiosciencereview.com/forum/index.php?threads/floyd-tooles-toronto-aes-presentation-from-october-28-2025.67011/#post-2647340 Here tell Dr. Toole that there need measure with laser vibrometer at same time at...

Of course, the waveform changes. An ideal speaker adds no phase shift between the fundamental and the harmonic (0° phase). A poor-quality speaker, on the other hand, has uneven group delay: it emits the fundamental tone with a delay, while the harmonic is already present. My test is designed to...

there can create such test tones without phase shift and put it thru a allpass filter later. but when i create such tones with phase shift direct in generator give more control over the phase shift. with a allpass filter it is hard to get a value. that is small. or what allpass filter i need, to...

Hi I notice with the generator can hear phase shifts very good and this give some strange feeling in ears at 27 and - 27 degree more as at 0. for example in ABX a blind test i detect that in 7 out of 8 try Can you confirm that the 2. wave add a clean sine tone without distortion at the double...

Perhaps it would be a better idea—and easier to program—if the time for the SPL reading could also be adjusted within the SPL display? After all, displaying the spectrogram isn't the priority; the goal is simply to view the SPL at a specific point in time in order to observe room and loudspeaker...

did you not hear that the low bass come from left down side when you use REW generator and play sine from 30 upto 120 hz ?. I always like to know if there are more people that can hear the position of low bass too. for me when i place a subwoofer that have crossover also 50 hz it sound strange...

I let analyze the AI to show how many decay speed it have on problematic room modes. there is lots diffrence between speaker visible. diffrent placement can not explain that. of course on room modes when the case also resonate in this range, then levels get higher. I use old measure with 76 db...

On every new measure i do, room dimensions are set to 3 3 3 also on start rew new. I see in preferences no gui entries to save that. my very old measure when load have 0 0 0 . I change some measures to 3, 4, 2 but i see no solution that the settings are store and use for new measures . How...

Here can see the JBL 104 results at ~0 0 ms and 140 ms time. the bass port is on back, I measure in middle below bassport but the back show also port output. it decay much better as the focal. so speaker testers or developers need no laser to measure case resonances. the above graphic is not...

Hello I think now the Feature in spectrogram show slice at cursor is best to show the truth and detect bad speaker resonances or do room treatment. with this settings. I think when the overlay also allow the show slice at cursor feature, to compare diffrent measure easy help alot. the...
