actually the left and right tracks just say "pink noise 20hz to 20khz left channel only"
hey bro no need to appoligize for that, i understand completely, priorities,in fact i was just about to go to home depot to pick up some concrete for 15 sections of fence im putting up and noticed how quiet it is in my house, hey the baby is sleeping and the older one is in school, hmmm, i can still make it into work by 4, hopefully the wife is not napping, ....ummm, bye
yeah oh well, at least i made it to home depot and work on time
ok so Chad likes correlated, anyone else?
i am measuring left and right seperatly but wondered when i play both sides with correlated vs uncorrelated which is more accurate to whats really going on, or should i just stfu and split the difference,thanks
It does make a difference whether it's in stereo or mono. A large difference actually. Stereo pink noise is 'uncorrelated'. Therefore it is not associated with the pink noise on the other channel. This minimizes problems with standing waves, etc. Mono pink noise does not share this attribute. This is easy to test. Play stereo pink noise and try to set your time alignment. You can't.
The reason is that the left and right speakers must have a similar signal for us to compare the distance between them based on time differences. We will place the soundstage using SPL with stereo pink noise. Mono pink noise has the same signal through both speakers at the same time so we can compare the time differences between the two sources. Therefore, we can hear the soundstage moving across the vehicle with mono pink noise while changing the TA settings on our processors.
Basically we set frequency response using uncorrelated (stereo) pink noise. We set time alignment by ear using correlated (mono) pink noise. (bold emphasis mine)
