    mini dsp hears show always too much in spl meter and can not calibrate

    As far i understand the sens factor is only in the cal file so i need edit it. but they write in manual in https://www.minidsp.com/images/documents/EARS%20User%20Manual.pdf page 17 stand that the preamp level can change and after a reload of the same cal file the calibration should be...

    mini dsp hears show always too much in spl meter and can not calibrate

    thats really strange how this hears can change the gain setting with dip switches (between 0 db and 36 db. it work really because it can see that dbfs value when have ambient noise change. after such a change and restart of REW spl show near same too high SPL value between 0 and 18 db. the write...

    mini dsp hears show always too much in spl meter and can not calibrate

    I am not the only with the problem. I have put the rta with the hears and with my soundlevel meter calibratet microphone in a post to thos thread. at 1 khz the hears show 20 db too much spl. so seem i need change sens factor to 21 db...

    mini dsp hears show always too much in spl meter and can not calibrate

    thanks, I find other thing that cause the problem. it is control input volume setting In java audio. when i choose the hears rew select automatic 0,53 . when i switch to my analog microphone input the values stay on 0.53 . but my analog microphone have 0.71. So this value is not store for every...

    mini dsp hears show always too much in spl meter and can not calibrate

    does rew support the phase value of correction file ? . is this important phase shift ? the correction file l(can download for my serial number) contain this. I delete sens factor in my test file. the text sens factor i remove in my testfile but REW allow me not to calibrate

    mini dsp hears show always too much in spl meter and can not calibrate

    Hello I have done a testfile which contain no sensivity data and i want calibrate but REW do not allow calibrate. I have a ambient noise db(A) in my room of around 35 db. the hears have dip switches. in the default (18 db set in hears) rew spl meter show around 57 db(A). when i switch to 0 db...

    is this possible that GD of a 88 hz Q10 -8 db Filter is -16 ms ?

    I have with GD measure of EQ find EQ settings that have much less and smoother group delay changes. It sound really much better. in the critical ITD range from 100 hz GD is nearly linear. the bass boost of the 60 hz have only 6 ms. can hear the diffrence very much on songs with much level...

    is this possible that GD of a 88 hz Q10 -8 db Filter is -16 ms ?

    I have no spreadsheet. rew have for Y . osciloscope also have a channel X offset. have such a setting in rew help alot or the osciloscope support the loopback delay parameter . because speakers look better with continues measure signals than uncontinous music signals it usefull to have a more...

    is this possible that GD of a 88 hz Q10 -8 db Filter is -16 ms ?

    Is there a way that it is possible to shift channel 1 or channel 2 in X without steps so it is possible to use mathfunction channel 1-channel 2 to show the diffrence better ?

    is this possible that GD of a 88 hz Q10 -8 db Filter is -16 ms ?

    I do this test to see whats the most important problem. So i think because the correction eq sound not so bad on headphones as on speakers it is mostly speaker problem because the speakers are very worse at 100 hz in precission. i test also with a CEA 2010 burst 160 hz and 300 hz and 800 hz ...

    is this possible that GD of a 88 hz Q10 -8 db Filter is -16 ms ?

    the cancelation seem help only a little. dirac look and sound even more worse. When i use this correctiion on headphones after several minutes hear my brain can correct this to a good sound and not muddy. but because the error of speakers(see burst results) and eq together is too much errors...

    is this possible that GD of a 88 hz Q10 -8 db Filter is -16 ms ?

    Hello please see screesnhot. this large group delays happen with high Q. anyway i compare my EQ settings and other speaker correction from sonarworks , arc 2.5, mathroom and notice all i find sound worsest(but look better in FR) have large group delay from EQ. I use for test the speaker output...

    which is the more precise speaker

    then maybe the main problem is that the peak is so much delayed. more than 10 ms. see screesnhot. I hear on speaker mudd sound when i boost 150 hz around. on headphone sound not muddy also when i boost 150 hz alot (both are calibrate). the signal look same from distance 1 cm upto 10 cm. so i...

    which is the more precise speaker

    ok, then it seem phase that need correct can not see on excess phase. without EQ the phase look more worse as excess phase. but it explain more wy the osciloscope display look so much diffrent without EQ the phase at 100 hz is 255 deg and 500 hz it is 388 deg. its diffrence of 133 degree. thats...

    which is the more precise speaker

    I notice that the excess phase did not show phase shifts from EQ because min phase contain too the phase shifts of the EQ. I mean this strong phase jump at 500 hz is only very few see in excess phase curve. wy this is not show ?. i use no smooth and no window and measure 1 cm away from...
