Equalizer APO enjoyer posted a comment on discussion General Discussion
Thank you for sharing! Had trouble finding these entries as well. In my case, I had to fully reopen (remove and add again) the "problematic" fabfilter plugin in APO Config Editor while Process Monitor was running. That way, it detected more of the plugin's reg keys and the "Load Image" operation, which I wasn't able to find before. Then, as Peter said, the needed entries can be found sandwiched between "Load Image" operation and "HKLM\Software\FabFilter\PluginName" regkey, as on his screenshot. Make...

Peter Verbeek posted a comment on ticket #331
Thanks for this post. I've seen this a few times before. A device can be manipulated (for instance by Peace) and still the Configuration Editor (and probably Device Selector) detects that Equalizer APO isn't installed. This is already a clue in itself. Unfortunately, I'm not the programmer so I don't know what this clue is really saying.

TITTLE UPDATE: This problem is not related to ASIO, as I discovered and reported in a future comment here. Seems like I never opened a ticket for this issue before, so despite of me creating a Discussion Topic in the past, there has never been a solution for it, and now that the issue has become even more problematic then I think its now worth creating a ticket for it.

By the way, I forgot to add this: Every time I open the Editor, an alert window appears that says "APO not installed to device: Equalizer APO has not been installed to the selected device,. Do you want to run the Device Selector application to fix the problem?" But this is wrong since I already installed the device. And yes, the original problem still persist to this day.....

Hi. I would like to report a problem/bug I have encountered. I have Windows 10, I am using EqualizerAPO with some filters in it (Eq and Volume/Amplitude filters) and I am also using Voicemeeter, everything is updated. When I am changing between configurations or just turning on/off any of the filters, EqualizerAPO suddenly stops working because I can't hear any change to the sound, but the software itself doesn't crash because I can still move sliders, parameters, etc. This also happens randomly,...

I think WhatsApp Desktop is using Windows’ communications audio path, which bypasses EQ APO, so the effects don’t apply there even though they work everywhere else. A practical workaround is to disable Handsfree Telephony and other communication-related settings in your audio device properties, or try using WhatsApp Web instead, which doesn’t bypass EQ APO. If you want a smoother experience with enhanced features, some users also switch to WhatsApp mods like whatsapp plus dorado, which sometimes...

That's right. There's only a task in the Scheduler. When TinyWall isn't preventing internet access for UpdateChecker.exe then that's okay. However, I still got this error popup. This got annoying. Besides, as developer of Peace I don't need a message when Equalizer APO is updated.
-
faaard7 posted a comment on discussion General Discussion
Thank you very much Peter Verbeek! I disabled the task from Task Scheduler and I'll see if that helps in the next startup & logon. Strangely, there's no shortcut to UpdateChecker.exe in my startup folder but I found the file in C:\Program Files\EqualizerAPO. I'll create an exception in TinyWall for that.
-
Just found out that the Equalizer APO Update Checker is in the Windows Task Scheduler. You might delete this task as it's activated at user logon: - Start the Task Scheduler. - Scroll down in the Active Tasks list to "EqualizerAPOUpdateChecker" task. - Double click on it. - Either remove the task by clicking on the delete icon in the right pane - or disable it by the disable icon.
-
This message isn't from Peace so unchecking "Check for a newer Peace version" doesn't do anything. It's a message by Equalizer APO or to be more specific, by an executable file called "UpdateChecker.exe" which is located in your Windows startup menu folder: c:\Users\pever\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup Unfortunately, Microsoft hides this folder from us by default so you need to make it appear by changing the "show hidden and system files" setting which should be available...
-
I updated Equalizer APO and Peace, after that every time I restart my computer I get a "error while checkin for update" "permission denied" banner, after logging in to Windows. I have unchecked "Check for a newer Peace version" but it doesn't help. I do have a third party firewall, TinyWall, where I've set C:\Program Files\EqualizerAPO\config\Peace.exe to have unrestricted access to internet. Any tips what to do next? Is there some other component that needs an internet access?

Phil Davis posted a comment on discussion General Discussion
I had to reinstall Windows 11 from scratch, it's been a long time actually for me anyway. I installed everything that popped into my head, system platform drivers, CPU drivers, video card drivers, all that stuff Then I installed Equalizer APO and things started to get wonky. Are you familiar with the copilot AI? It could hear me perfectly fine, but anything it tried to say to me was completely lost. Stranger yet, I set up some settings in Equalizer APO to redirect the low base to my subwoofer, and...

Commonly it's about 2 things. Either some former audio device or devices got left after a Windows update installed a new one or new ones. A former device can be "empty" causing a crash of both apps. Or an audio device most likely a Bluetooth or USB one isn't complete causing the crash. In both cases both apps can't fully retrieve the specifications of audio devices from the Windows registry and crash. Unfortunately, the developer hasn't address these issues yet. On the other hand, empty or not fully...

When using graphic EQ you can either change the frequencies at the right (by double clicking on them) or go to the actual command and enter it there. This is done by clicking on the (small) left edit text icon.
-
Juha posted a comment on discussion General Discussion
Hmm... you can EQ any frequency you want with EqualizerAPO. If you use Configuration Editor just pick filter type and then set the (cut-off/center) frequency and other settings (Q/BW, Gain). If you use GraphicEQ, be aware that it maybe is different type EQ compared to Audeze EQ yoiu mentioned. You can also write those filters manually int config.txt (or other name file if you include it to config.txt). Assuming Audeze EQ uses Peaking IIR filters, just add peaking filter with suitable settings. Filter:...

Hello im new to eq stuff. i have downloaded the equalizer apo since it was reccomended to me and im trying to get these same eq settings from the audeze eq that i have but theres no band for the 32Hz and 64Hz in the equalizer app like there is in the audeze app theyre the only bands that's missing so i am confused on what to do now. does anyone know how to get these same settings

https://github.com/TheFireKahuna/equalizerAPO64/releases/tag/1.4.2_4 Full release out, includes an AVX512 build again, with AVX512 now used in all dependencies including FFTW3. Hopefully fixes any lingering convolution/mono issues too. Also includes an ARM64 build all via the automated CI pipeline, with all dependencies and the Qt apps compiled for ARM, essentially a start-to-end fully native ARM build. Definitely needs testing, but with this addition all modern build targets should be covered. No...

It'e really looking like the critical system error. If you have solved this can you guide how you have solved this error

Just posting here to let people know that this effort has been revived, a version of EAPO with Double Precision processing (64-bit audio pipeline) & support for AVX2/AVX512 is released here. Should work fine for most uses cases, and work on any Intel CPU post 2013, and any AMD CPU post 2015. Many users may not notice an audible difference, if you're using a more complex audio setup however there should be a quality improvement. Namely overlapping effects, multiple convolution filters, complex effect...

https://github.com/TheFireKahuna/equalizerAPO64/releases/tag/1.4.2_ci_test I've managed to get a fully automated CI pipeline working for 64 bit EqualizerAPO 1.4.2 builds, with everything rebuilt (including the Editor) and the installer packaged on completion. Uses VC 2022 and AVX2 only for now (need to add multiple targets to the CI build to restore AVX-512) Also support for muparserx 4.0.12, and built with AOCL-FFTW3 for better perf with AMD processors (plus a more modern Windows build and newer...

So Equalizer APO is only installed on the mic and not on any other (output) device?

Yossi posted a comment on discussion General Discussion
Using Razer Freyja Haptic chair with APO no matter which Heusvi I choose just letting it work in the mix causing the chair to stop vibrating properly, like it loses all the bass. I tried many sound cards and it happened on all of them no matter if it's LGX/MFX/SFX on any of them. I have no idea why it is happening. does anyone have any idea what and how can I fix this?
-
That's unfortunate. I'm not sure what you can do. Looking at your screenshot I don't see any loudspeakers/headphones device (line out/headphones connector). Commonly a computer has at least such a device. We need to establish if Equalizer APO can be installed generally speaking so it would be nice to see if Equalizer APO can be installed on that common device.

After searching the web it seems that 0x88890004 has to do with audio devices or perhaps in your case only 1 problem audio device. While 24H2 is trash, I have all kinds of issues but luckily no Equalizer APO ones, it could be that the audio devices were renewed causing their former devices still installed but disabled. If so, this causes the Device Selector and Configuration Editor of Equalizer APO to malfunction. Either these apps can't get the specs of one audio device causing a crash or error...

Hi guys, Yesterday I updated to Windows 24H2 and noticed my EQ stopped working. When I tried to reinstall Equalizer APO it keeps throwing up error code 0x88890004, even when trying to install in different modes through the troubleshoot installer. Any idea what I can try to resolve this? Thanks.

If your Equalizer is not opening at all, it might be due to app compatibility issues—this happens in many older apps and games too. For example, in car parking multiplayer old versions, some features stop working because they aren’t fully supported on newer devices.
-
It seems that for the 3 devices you have installed Equalizer APO on, all 3 has trouble with any of the 3 APO techniques (APO = audio processing object as in sound effect/enhancement). Did you run the Device Selector with administrative rights (right mouse click menu -> Run as administrator)? This is needed for good access to the Windows registry. And talking about this registry, it could be that an overactive anti-malware app or firewall is blocking the Device Selector from accessing the registry....

It sounds like you have run into the long-standing conflict between Equalizer APO and Microsoft’s Protected Audio Path, which Edge and the Netflix app rely on for 1080p playback, so unfortunately there is no reliable fix unless Microsoft changes how protected output is handled; most users end up choosing between keeping APO enabled for system-wide EQ or using a browser that supports Netflix’s higher-resolution DRM without modification, and if you prefer not to downgrade to 720p, your best workaround...

Mary Kline posted a comment on discussion General Discussion
It seems sense that you would choose to use Edge for Netflix in order to take advantage of 1080p streaming, as other browsers like Firefox only offer 720p. Regretfully, Equaliser APO (1.1.1) doesn't appear to function well with Netflix on Edge in Windows 10. This could be due to the browser's audio processing limits or the way it handles DRM content. It's unpleasant to be limited in this way, but you can get around it by investigating other platforms that give you more control over audio settings...

Version 1.4.2
-
Fixed: Commands GraphicEQ and Convolution were often not working correctly for Bluetooth devices on Windows 11.
-
Fixed: FFTW could not be loaded on CPUs without AVX support since version 1.4.1, leading to crashes e.g. when opening Configuration Editor.
-
Added: Translation to French (user-contributed).
-
Added: Translation to Simplified Chinese by Chenx221 and 大眼仔~旭 (Wang Chenxu)
-
Fixed: Voicemeeter Banana was not correctly detected with current Voicemeeter installer. Only one Voicemeeter output was showing in Device Selector.
-
Version 1.4.1
-
Added: Update Checker that can be enabled in the installer. If enabled, will check for a new version daily and show a popup window when an update is available.
-
Added: Support for ARM64 architecture (Windows on ARM). Same functionality as on 32 bit (now x86) and 64 bit (now x64) versions but limited VST support as native ARM64 VST plugins are rare.
-
Version 1.4
-
Improved: Configuration Editor and Device Selector now support dark mode, controlled by the Windows Settings app.
-
Added: Device Selector as a Qt-based replacement for the Configurator that has support for (DPI) scaling and includes a dialog for testing that the APO installation works correctly, with automatic adjustment of the installation mode if necessary.
-
Version 1.3.2
-
Improved: Configurator can now restart the Windows audio service to avoid the need for a reboot. This also allows to update Equalizer APO via setup without reboot.
-
Fixed: Configuration Editor crashed on startup when analysis panel had been detached.
-
Fixed: Notch filter in Configuration Editor was incorrectly set to "Fixed Q" instead of "Q factor" after load when the Q factor had been adjusted before.
-
Version 1.3
-
Fixed: Bluetooth devices on Windows 11 often did not work when multiple devices were combined (headphones and hands-free). In this case, installation as SFX/MFX is now used by default as EFX does not work.
-
Fixed: Reimplemented Voicemeeter integration (based on official examples) to fix stuttering issues.
-
Improved: On Windows 8.1 and newer, installation as SFX/EFX is now the default. This should remove the need to use the troubleshooting options for most users.
-
Improved: Updated to Visual Studio 2019 and Qt 5.15.2. Running Equalizer APO requires Universal CRT now, which means that Windows versions before 10 may need additional Windows updates or the Visual C++ Redistributable for Visual Studio 2015 - 2019 needs to be installed (installer provides assistance).
-
Version 1.2.1
-
Added: Logical operator "not" to expression language (see e.g. If and Eval commands).
-
Fixed: Channel "SUB" is now correctly called "LFE". The name "SUB" is still supported for compatibility with existing configurations.
-
Improved: Shelving filters (LS(C), HS(C)) can now also use Q instead of slope.
-
Added: Voicemeeter Potato support
-
Improved: Tabs can be closed by middle click in the Configuration Editor. Ctrl+A can be used to select all rows.
-
Version 1.2
-
Fixed: When removing a row with embedded VST plugin, the Configuration Editor crashed.
-
Fixed: When removing a row with embedded VST plugin, the Configuration Editor crashed.
-
Fixed: Crash during initialization of GraphicEQ/Convolution filters when loading the configuration in multiple threads concurrently. This occurred most often when using GraphicEQ both for playback and capture devices.
