reading up on your EQ I was wondering would it be possible to include a suggested quality setting figure somewhere in the gui.
I see that you say it relates to the Q of the filter - it'd be cool to have a small numeric reading somewhere to show what setting would be required for best results at the current Q.
Kind regards

Hi david.
I've been busy with another project so I haven't been able to test until today.
These new versions worked flawlessly this far.
Excellent!

David, is it possible to make a true bypass mode for each band in the PLParEQ4 plugin? As it is now I get 4 allpass filters in a row when using the default phase-warped mode. I don't know if this is a good thing.. I'd prefere the first 'band' to be a bypass mode.
Cheers!

Hi David,
this is great. Peak mode 3 seems to have a problem with the Q. I didn't read up on the Cambridge eq so I dunno if this is inteded but I don't think so. The Q is way to narrow compared to the other peak modes.
All the best, FRitz
P.S. Please check your KvR PMs.

I think it's intended that way. Btw, David, which mode is the original mode? I've added old versions of PLParEQ1 to several projects and was hoping that this new version was backwards compatible. If it isn't then it's not really a big deal.. would just be a nice bonus.

To be perfectly honest, I didn't even open the old projects yet and check. David seems to be replying so quickly that it would be quicker trough here (not at my main system.. the wife's got me sitting in the kitchen on this laptop again coz she wants to sleep 
).

Hehe,
OK, before I tell you that I made the phase cancellation test I tell you that I really heard the difference. The old mode isn't in there anymore.
Best wishes, FRitz

Yes,
I checked the new peak modes more in depth and I like them. Mostly one and two, #3 is very special but really cool also. The original peak algo sounds more neutral in several situations so that I would love to get it also. I mean I already have it, but ...
Sorry if this sounds spoiled.
Thanx a lot again, David!

Hmm?? Cambridge Type 1 is the original peaking EQ mode. No changes at all from before.
In PLParEQ4, I see that it likes to default to APF mode... that has to do with arcania in the program, and I can fix it. But bypass is the next tick up on the slider -- called Inactive. GUI issues...sheesh!
Version 1.45 fixes that default behavior, and one, more serious flaw... During bypass filtering the system should behave as a wire with delay. Instead, prior to 1.45 it was still upsampling/downsampling even though no filtering was being applied. That has now been fixed.
Cambridge type 3 attempts (only loosely) to keep the approximate area under the curve constant with gain. So you just set a Q to whatever, and then as you raise the gain, it will gradually increase -- so that the -3 dB points do indeed narrow in on the peak. That's exactly what happens in dipping mode on Type 2 as well. Type 1 is the old standard peaking/dipping that you always had.
I found that adhering too closely to the proviso that area is conserved under the peak with changing gain made the filters appear to narrow too quickly. We use a looser interpretation now, but along the same lines of intent...
The intention here is that by changing the Q of the filter with increasing peak gain, it becomes more what the "ear" would expect. Whereas, constant Q filters encompass ever wider portions of the spectrum as the gain increases.
There really is no "correct" way to do this kind of thing... as It all depends on the sound field properties, and how many critical bands are included under the peak. As you narrow below one critical bandwidth, the loudness summation becomes completely different than when you encompass many critical bandwidths.. so all of this is very crude by any perceptual standards. We can only hope to get approximately right...
See version 1.45 on the web.
