Ok this is a bit over my head, even if it should be the base...Oh I HaTE it when that happens ugh!!
Or I save something as horn and over rite it as mid .
So I'm positive Dirac filters clip the signal now if the magnitude isn't within about 6db. A pretty good pre tune is a absolute necessity. I think I've solved my clipping issues now for good. I was thinking as long as I'm setting a target under its 0db line it won't use boost well that's 0dbfs not 0db. It's normalized and even says it on the screen so if I draw my target anywhere above any of the "all before" it in fact does add boost. It brings everything up to 0dbfs which is the absolute max in the digital world. Can't boost past 0dbfs or massive clipping starts. So the only way to get a really really good tune would be to have as flat as possible magnitude responce so that no part of the "all before" is too low.
So that's a test signal and I don't know it's crest I'm assuming it's about 3 to 6db as is most signal generators. But I don't know so I'm going to have to hook up a scope and test. If music has a transient louder than the test signal guess what, yep the closer you get to 0dbfs the more shit will clip. So any erratic changes in magnitude could cause a boost if set wrong and if set right won't leave enough gain to get enough useable output meaning system will loose a lot of signal to cutting. Inverse filters are a bitch. So tomorrow I'm going to spend some quality time with good old fashioned RTA and get shit flat than tune. I've just haven't (still) because Dirac does such a good job at it. But it really is important now. Use eq cuts on output and save precious digital headroom
I got a much better tune but tomorrow I'm going to make the end all (for this week ) tune.
I sometime had some clippings depending of the tune, but I only noticed it on highs. But it can also be my tracks, in fact more often.
Or when I noticed some heavy boosts in Dirac (on mids) I usually lowered the ddrc knob (or default preset) to -3 or 6db. Seemed to do the trick.
Is this a good fix?
But I try to stay safe, either in the Cdsp (input -Xdb, X being the max PEQ I used), and then low target in Dirac.
Of course the final output is much lower, but I never missed juice for now.
But I could imagine that it’s not optimum.
I should try to keep the laptop synced during a drive, to see what output level I usually listen to.
Btw I have a dbC meter that I check sometime when loud, to not go to crazy
But I use it more as relative levels as I’m not sure it’s accurate.
Then I managed to get back my good tune, or at least find out which one it was.
By disconnecting each speaker and playing sweeps, got the XO and levels of the tune.
But the strange thing is, it should not be the one that correspond to the Dirac preset (preset 1 on C-dsp for preset 1 in Dirac, 2 to 2 etc).
I mean, it should not be the best combo but still it’s the one I like
I’ll make another Dirac pass once it’s quiet outside...
