Pro-Q 4 - Spectral Dynamics Threshold Tilt (Feature Request)
Hi there,
I've been using Pro-Q 4 for the past day, but have noticed that when using a broad EQ band, the spectral intensity isn't reduced in the upper part of the band.
I tested with flat white noise (for "equal intensity") and I get equal reduction across a broad EQ band. However, white noise isn't very musical sounding. When testing with pink noise for a more "musical" sound, the spectral reduction works much harder on the lower part of the EQ band, and the higher part of the band is hardly reduced in intensity.
Would it be possible implement a feature of "Spectrum Tilt" for the spectral dynamics threshold? Or even changing the tilt so it conform to -3dB/oct. This would make broad EQ bands more usable with spectral dynamics. Narrow EQ bands seem to work fine since they're not spread across a wide range of frequencies.
Regards, Jim.
Hi Jim,
This is a very good point, and we'll think about it for a future update. I don't think we can change the default tilt at this point since it would break existing sessions...
Cheers,
Thanks Frederik.
Totally understandable that changing the default threshold tilt would break existing sessions. Hope it's possible to implement it as an additional feature in a future update. Would be quite useful!
Thanks again.
Just tried some sidechaining with ProQ4 and no matter how i set it, it nearly always triggers only the lower part of the band - to make it effective i need to make at least two bands, which makes the workflow annoying enough that i'd rather just open soothe2 to make it work.
TLDR: yes please add spectrum tilt.
Cosigned - please add this feature.
For clarity sake this should simply be tied to the tilt setting... because then it becomes "what you see is what you get"
Sorry I meant slope setting of the analyzer...
in reply to pd80:
clever idea to link those slopes, not sure i agree with it though. Many users have one analyzer slope setting they're used to, but different audio sources can call for different tilt controls. I think I'd prefer a separate knob or slider.
I also want something like this. A simple switch enabling a 3db/octave slope would be great! Variable slope like DSEQ would be even better.
I've also done a test with white and pink noise testing the behavior of the spectral dynamics and the result makes me quite skeptical of using it. It might end up making the mix brighter then preferred. The same test with Soothe 2 shows that it reacts more in line with an equal loudness contour. This should definitely be added as an option to Pro Q4.
Another vote for this! As a long-time Soothe user, I had literally never thought about the shape of the threshold or whatever because it just did what I expected it to do. Not the case in Pro-Q. Especially since, to me, one of the cool things about spectral dynamics being in Pro-Q is the ability to make a little boost around the area you're spectrally cutting, but as is, I'd really need to use two bands, one for the spectral cut, and another one centered a little lower for boost.
DO NOT CHANGE THIS !!!!!!
The way it is now, it grabs the fundamentals more than its harmonics which makes sense!!!
→ very music sounding !!!!
This is the difference between ProQ4 and Soothe and THIS MUST NOT BE CHANGED!
I’m so annoyed by all those people who try to turn ProQ4 into Soothe!!!
Just. Use. Soothe!!!
I’m so tired of this!
Paul, FabFilter clearly said in the second comment in this thread that they will not change default behavior due to backward compatibility, so your exclamation tantrum is really unnecessary.
And spectral dynamics as a concept isn't meant solely to "apply to a single tone and notch the fundamentals"
Granted that you actually have Soothe, Soothe2:
- can't boost
- is another plugin altogether meaning you need to add another plugin in the chain for a simple fix
- costs 200€
- has a bunch of additional features someone might not need at all, because all they need is ProQ4 with a slight detection adjustment.
And most spectral dynamic plugins weight against pink-noise (or similar) curves because it's generally more useful.
Because, as you might not know, Fundamental is louder than harmonics in the first place, so even if weighted against pink noise as opposed to white noise, without adjusting, spectral dynamics will likely bias towards the low end anyway.
Ploki, this is what Fabfilter said:
"I don't think we can change the default tilt at this point since it would break existing sessions..."
So, they are not 100% saying they won't change the default behaviour.
Not against a tilt at all.
I just can't hear the "Soothe equality idea" any more...
To be fair, Paul, I don't think it's that we all want this to be Soothe (I know I certainly don't), but comparing it to Soothe is just an easy way to describe the issue I'm having with ProQ4 (especially since I have NO clue about how any of the backend for spectral dynamics works). I THINK I'm personally preferring the sound of ProQ4 and definitely like the way it's incorporated into the EQ, but it just feels like it's kinda fighting me and I have to work around it to get it to do what I want. I don't have that issue with Soothe and am hoping in a future update, I won't with this either!
What do you want Pro-Q4 to do that you can't achieve when Soothe does the job?
These are 2 different plugins with Soothe obviously having much more control. Soothe can be extreme with narrow Q, having dips running all over the spectrum. Pro-Q is more natural since it grabs the fundamental more than its harmonics. I like that. This is an inherent property that Soothe can't achieve very easily. Although possible, you need to work with the EQ bands and pronounce the fundamentals.
As I'm writing I'm thinking of a future feature where it's possible to duplicate EQ bands in Pro-Q4 so that you can duplicate one spectral mode setting and have quicker separation control.
All that said, a tilt function would not hurt anyone.
Paul, you seem to be arguing against every one else simply asking for this as an additional option. You will lose nothing!
In addition not all of us own or are planning on buying Soothe, so adding additional more soothe-like behavioural option to Q4 only strengthens it even further as a plugin, its all good :)
Not arguing. I have a strong opinion about Soothe being abused by many. I wonder if people know how to use Soothe at all. It can mess up things quickly. And I also believe that FF was very aware of what they were doing. I don't have something against new features.
Whatever :)
That's all well and good, but I echo Laurence's opinion: if you go wider with ProQ4 spectral dynamics, you fight against it.
Frankly going wider is pointless as it currently behaves because it's biased towards low end so much, you're better off just creating another band. Which adds unnecessary complexity and slows down workflow.
This isn't an unreasonable request, and considering they added a bunch of new features, it's not unexpected that things pop up when a bigger user-base gets their hands on it. Beta tester can do much but there's bound to be things that escapes through to the release, that's why updates happen
1+ for tilt option.
