"Open panel" causes Equalizer APO Configuration Editor to crash.

[YellowOnion]

Is there some way to control the amount of noise suppression?

[werman]

The only configuration know is VAD threshold (#20), it is zero for VST plugin by default and could be tuned, however I don't think anyone tested if this parameter works with Equalizer APO.

Does it at least work if you don't try to change parameters?

[YellowOnion]

Yeah it works, My sound card just has heaps of noise, was hoping to boost it a little. definitely better than ReaFIR VST

[werman]

Does it have any logs, is there anything?

[YellowOnion]

No sorry, just looks like it crashes to desktop. Maybe just a bug in the UI expecting the plugin to have a UI component?

[werman]

I think logs could be found at C:\Windows\ServiceProfiles\LocalService\AppData\Local\Temp\EqualizerAPO

Maybe just a bug in the UI expecting the plugin to have a UI component?

It may be, but I'd have to spin a windows vm to have a better understanding...

2020-07-17 05:45:09.154 4952 C98F3980 (EqualizerAPO.cpp:245): Failure in IsInputFormatSupported of child apo

I get this message repeatedly but it predates me using this plugin.

[PhantomGamers]

I know this isn't helpful at all but I just wanted to say I'm having the same issue and I couldn't find any useful logs from Equalizer, closest thing I've found is %localappdata%\CrashDumps but the dump only says "The thread tried to read from or write to a virtual address for which it does not have the appropriate access."

Also oddly I don't have this C:\Windows\ServiceProfiles\LocalService\AppData\Local\Temp\EqualizerAPO folder you mentioned.

[githubplanetarparrot]

I am encountering the same issue.

It would be great, that it could be edited in equalizer apo.

[theglobe]

There is only one parameter to be edited in this plugin, for most users the default value is the best choice. So there is no need to edit this parameter. Just load the plugin and resist the temptation to click the button. :)

If you need to edit it, here is perhaps a workaround:
After loading the plugin in the Editor, choose Options -> Embed and then disable it again (it is a check box). Now choose Edit (in the drop down menu to the left) and you will see a configuration line with the name of the parameter and floating point value. Here you can set the value of the parameter, 0 to 1 (with decimals, outside this range crashes Eq APO).

This configuration line is also written to the config file, and you can also edit it there.

Eq APO differs from other hosts in that it does not provide GUI controls to the plugin. Interestingly, Embed is also supposed to open the plugins controls but does not crash Eq APO.

[werman]

Yes, I actually installed Windows in a VM and can confirm that the crash is due to Eq APO not handling correctly the lack of GUI in the plugin.

"Options -> Embed" is indeed a solution.

[theglobe]

I found this source code of Equalizer APO: https://github.com/mirror/equalizerapo/blob/master/helpers/VSTPluginInstance.cpp
(Is this the official source?)

In particular this piece

void VSTPluginInstance::startEditing(HWND hWnd, short* width, short* height)
{
	if (effect == NULL)
		return;

	VstRect* rect;
	effect->dispatcher(effect, effEditGetRect, 0, 0, &rect, 0.0f);
	effect->dispatcher(effect, effEditOpen, 0, 0, hWnd, 0.0f);
	effect->dispatcher(effect, effEditGetRect, 0, 0, &rect, 0.0f);

	*width = rect->right - rect->left;
	*height = rect->bottom - rect->top;
}

So in our case we have an effect, but no implementation of getRect(), thus rect will be unassigned.

It is possible to fix, by implementing getRect() that returns a rect set to some values, which would lead to hosts opening an empty window, just for the sake of fixing a bug in Equalizer APO.

Hello, can you give me an example of how to change the parameters?

VSTPlugin: Library "C:\Program Files\VSTPlugins\rrnNoise\librnnoise_vst.dll"

https://sourceforge.net/p/equalizerapo/tickets/138/

[werman]

@theglobe Thank you for analysis!

For Equalizer APO it would be correct to initialize rect to nullptr and check it after effEditGetRect.

I'm not sure about having a workaround since what if some other host checks if a plugin has GUI by checking the returned rect.

Can you confirm that the VAD threshold works with EqualizerAPO? Also, the README states that its default is 50% - how does that translate to the float value of the parameter?

Stopped working after EQ APO 1.3.

Released v1.01, there is GUI now.
