EQ analyser does not reset completely

[Oli Ullmann]

EQ Analyser does not reset completely. Even if there is no longer an audio signal, the analyser displays something. This also happens in the EQ itself. (See screenshot)

Here is a demo snippet:

@Oli-Ullmann I can help you with this one — I'm just in the middle of debugging something else, but then I've got ya.

[Oli Ullmann]

@clevername27
Oh, that's great! Thank you very much! :-)

[clevername27]

@Oli-Ullmann I can't load the snippet right now. Are you iterating through every parameter of every band?

[clevername27]

@Oli-Ullmann In your snippet, where your code to reset the EQ?

[Oli Ullmann]

@clevername27
Nothing in my code resets the EQ. Is that necessary?

[Matt_SF]

@Oli-Ullmann It's not a bug. This is happenning because the EQ is set to be 'suspendedOnSilence'.
See the little "S" over the module's level meter ?

When there's no signal, the module is bypassed and the analyzer retains the last known values. that's why it seems to be 'frozen' .
(The feature/issues are discussed here : https://forum.hise.audio/topic/7400/new-feature-suspendonsilence/43)

You can change this by editing this line:

	bool isSuspendedOnSilence() const final override
	{
		return true; // change to false
	}

in

"...HISE/hi_core/hi_modules/effects/fx/CurveEq.h"
// line 193

You'll have to recompile HISE afterwards.

@Matt_SF
Thank you very much for your answer!

I can understand why the default value is “true”. On the other hand, a value of “false” would make more sense for day-to-day work. Don't you think so?

Anyway - I'll try it out. Thank you very much! :-)

[Matt_SF]

@Oli-Ullmann It's set to 'true' by default in order to save CPU but in the case of the built-in EQ, unless you have dozen of them, I think you can indeed deactivate it :)
