    256 k 4 times choose. noise floor in distortion measure is much higher as 5. and 7. harmonic but when do sine and RTA noise floor is much lower

    so when i do 4 measure sweeps i get 6 db less noise floor which mean half. when noise floor is at a freuency 0.1% then i get on this frequency only 0.05% noise floor level ?. high harmonic 7. th and 9. th sound really bad even if it is only 0.1% 0.05% is then good for my ears.

    256 k 4 times choose. noise floor in distortion measure is much higher as 5. and 7. harmonic but when do sine and RTA noise floor is much lower

    I understand that in RTA with constant frequency noise floor is lower as a single sweep.. but i use 4 sweeps(set in measure dialog). it reduce noise floor not much. see screenshots for compare here can see clear 5 and 7 harmonic here noise floor is much too heigh. how can get this less noise...

    Is it possible that the scope trigger start is when press play button in generator and stop when play in generator is stop ?

    when wave start begin at level 0(as the sine in the preview of rew do) then click i guess is create from brain. only what cause physically clicks is when a 80 hz sine begin for example at phase 179 position. then a high freq jump is create from 0 to 32767 FS (for 16 bit) which cause high freq click

    Is it possible that the scope trigger start is when press play button in generator and stop when play in generator is stop ?

    Hope this is not much work, the easiest way with less work is allow to switch off the fade in. I dont think a fade in is need

    1024 is largest i can use in ASIO, problem is same curve look a little diffrent. java sound i test too, too not correct but look diffrent too. should i upload screenshots ?. with which frequency you test the sine and you see it work ?

    it seem this problem happen on all generator waves that are fade in. because i see that in sine too

    Is it possible that the scope trigger start is when press play button in generator and stop when play in generator is stop ?

    I ask the question because i notice strange fade in when use multitone and loopback. on tone burst loopback all look good, so i assume not that it is a problem with my sound card. maybe the fade in can switch off ? ok burst loopback signal in scope strange fade in when use multitone or also sine

    Is it possible that the scope trigger start is when press play button in generator and stop when play in generator is stop ?

    Hello Also it is usefull when in the generator can load a wav and play it. this help driver developers and also speaker developers to see if the speaker/driver is better in transients as other speakers because can compare in the scope with the loopback signal. to test there can load short...

    can the room calculator in REW create a FR depend on room and spinorame FR data or own free field or near field measure easy ?

    and additional is it possible that the room calculator show frequency higher as 300 hz. i can easy create large dips at 300 hz with placement in the room calculator. so it is usefull to see at least upto 600 hz what happen

    can the room calculator in REW create a FR depend on room and spinorame FR data or own free field or near field measure easy ?

    Hi I think it is a great ide when the room calculator can easy create a FR of a measured speaker depend on the room sim settings. so can try out fast best positions for speakers. Is this possible as a enhancement ?. currently i see only the way create the FR of the room in rew with the buttons...

    does REW for frequency repsonse calculation also use phase values ?. I see at 500 hz gate with 9 ms and more do lots of phase change at 500 hz very fast in compare to gate with 8 ms . my impulse have very few reflections because of treated room. and there is nothing larger see between 8 and 9...

    I mean 185 degree is 1 cycle + 5 degree in unwrap mode and in wrap mode it get to 0 cycle 5 degree for 1 measure and the other measure have 0 cycle 179 degreee which cause huge phase diffrence between those to measure in wrap mode. and in unwrap mode it is small . diffrence 0 cycle 179 degree to...

    i notice clarity display look also not ok see screenshot. happen also with older measures other speakers in same way

    Alignment tool questions

    that the large dip happen i think is because REW calc 1 measure for example at phase 179 degree second is unwrapped 185 degree . so unwrappet very few phase diffrence but wrappet it is -175. so lots phase diffrence that which can explain the large dip . the trace arithmetric a+b tool do the...
