Sorry I wasn't here on the forum for a while. I'm glad that it helped some people. Writing this down was a hastle ^^' As mentioned this is not that easy, you have to take time and dig into it. This is not a trivial 5 min solution. Thanks to everyone who added info to tackle this. @Tony Manfredonia Yes these entries will be always there after restart, this doesn't matter. You have 30 days to delete them again. I have a batch file that removes them always on system start, so I don't have to deal with...

Thanks for reporting back 😃 Nice to hear that the issue got solved somehow. Indeed, probably by a Windows update although that doesn't give us a clue how's solved.

An Update: looks like it has been fixed after weeks of using the program and changing settings without crashing, probably after a Windows update, but I am not sure exactly why. But yeah, there is that.

No problem, George. Indeed, perhaps the next version.

George posted a comment on ticket #338
already tried with FiiO K9 disconnected. mic drivers from old cameras were cleaned along with the other ghost devices. did not uninstall all audio drivers. Some I can't, like hdmi audio from monitors. For the other drivers, it is too much work, and if that indeed is the culprit then the software won't work for me... Still I do not believe it is the drivers, FiiO is a widespread vendor, which many audiophiles use.. oh well, I gave it a try, lol. maybe I'll try next version, or if the developer wants...

Using Eset as AV. Even though no logs of blocking anything on Eset, I tried disabling it together with Windows defender, but to the same results. Good to try but that was to be expected. What happens when you start up the computer with the FiiO K9 disconnected? Same issue? Perhaps even uninstalling device drivers, just to see which one is the culprit when you install them one after the other. Anyway, when saying "mic drivers from old cameras" this could present a problem. I wish there was an easier...

Mostly audio devices from my 2 monitors connected through hdmi/displayport. Every time Nvidia GPU drivers update, those devices refresh...a couple old mic drivers from old cameras, and 1 old FiiO K9 device from when I changed the USB port. They all add up in the end.. lol No insider program. Latest "non preview" updates in Windows 11 Pro. Feb 26 as of now. Using Eset as AV. Even though no logs of blocking anything on Eset, I tried disabling it together with Windows defender, but to the same resu...

Wow, 22 ghost devices. That seems a lot. So there is yet another issue which my solver hasn't covered. I wish the developer would react on this matter. Unfortunately I don't know what it is about. There is the rare occasion of an overactive anti-malware app but I don't that's it. VirusTotal doesn't show anything on the editor nor on the device selector. Another equally rare is the crashing due to an issue of certain Windows updates. Are you on the Windows Insider Program for receiving the newest...

Thank you for the suggestion. Unfortunately it did not work. Even though "Equalizer APO issue solver" showed no error (attached) I went through the painful task of cleaning my registry, advanced run regedit (run as trustedinstaller) under: HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\MMDevices\Audio\Render deleted 22 ghost devices and left only the active ones. still it crashes with the same error..
-
Then it's about one or more removed audio devices of which the registry still has an entry. This can also be checked with the Equalizer APO issue solver (issue 7). It tries to detect this. Unfortunately this app can't correct this, especially knowing it's a tricky one to correct. One needs to use a good Windows registry cleaner or the Windows utility bdism.exe or even both.
-
tried that, no fix. Although it is understandable since there are no registry values to be corrupted. The editor and device selector, never did run, they crashed immediately.

Hello, I have tried to get this project to compile for 5 hours and failed. How exactly should the dependencies be isntalled? And how do I add the include paths in VS 2019? (I also tried with 2022) The documentation needs to be updated with a precise step-by-step explanation. I only want to adjust the wrong filter parameters in the loudness compensation plugin.
-
If this is a problem of corrupted registry key values in which the editor settings are stored you could use my Equalizer APO issue solver. This is issue in this app which is solved by deleting these key values so the editor creates them again at its startup.

I think It's actually okay for them to show back up after restart. in my case It still solves the problem for another 30 days
-
I don't know how to easy solve this (see comments below) but at least I can tell you that 'Instant Mode' has nothing to do with it. This checkbox unchecked causes that changes aren't picked up by the audio engine of Equalizer APO. This is quite pointless so this checkbox is pointless imo and should remain to be checked all times. It must be a license issue thing, meaning FabFilter doesn't have access to its license therefor keeps running in demo mode. Equalizer APO like any Audio Processing Object...

I've deleted all the regkeys and every restart they show back up. Right now I'm in Instant Mode on Equalizer APO (not sure if that makes a difference). But very eager to use my custom EQ headphone curve with FabFilter, and after the 30 day window despite being licensed, it no longer allows audio to go through :( Any further advice?

It seems sense that you would choose to use Edge for Netflix in order to take advantage of 1080p streaming, as other browsers, such as Firefox, only offer 720p. Unfortunately, Netflix on Edge in Windows 10 doesn't seem to perform well with Equaliser APO (1.1.1). This could be due to the browser's audio processing limits or the way it handles DRM content. It's unfortunate to be confined in this way, but you can get around it by researching other platforms that give you more control over audio settings...

Equalizer APO (1.1.1) running on Windows 10 has recently hit a frustrating snag with Netflix in Edge. The issue seems tied to a Windows or Edge update that conflicts with the audio driver, forcing users to delete the DisableProtectedAudioDG registry key and restart the audio service to get Netflix playing—but doing so breaks Equalizer APO. Even though the Configurator can restore Equalizer APO after a reboot, Netflix refuses to cooperate again, leaving you stuck choosing between sound customization...

VST3 support would definitely be a huge step forward, especially since many newer plugins are moving away from VST2, so having native compatibility or even a smoother workaround than savihost3x64 would make life much easier. If routing and device switching are the main pain points, deeper integration with tools like Equalizer APO could be a smart direction, as seamless audio handling really improves workflow. It kind of reminds me of how apps evolve over time to support modern formats—similar to...
-
That's because it crashes. If you were using Equalizer APO version 1.3 or lower then this is caused by a bug. After detaching the analysis panel (the graph window) this bug crashes the Configuration Editor at startup. Anyway, you could resolve this using my Equalizer APO issue resolver or by deleting the windowState key value from HKEY_CURRENT_USER\SOFTWARE\EqualizerAPO\Configuration Editor by using the Windows registry editor.

ive tried uninstalling reinstalling trying different versions of apo aswell as changed compatibility and running as admin, but my config editor will open for a second and then it just closes just doesnt work

It depends on the buzz. For instance, before Equalizer APO version 1.4.2 using graphic eq could result into buzzing or worse distortion. Amongst others that why my Peace equalizer app is using filters by default. But this buzzing/distortion was mainly on Bluetooth audio devices. Another cause can be the background noise. When amplifying the sound of your mic by a pre amp command (or in Peace by the pre amp slider) this noise gets amplified too. So either you put the mic closer to your mouth or try...

Gabriel Rodrigez posted a comment on ticket #344
You were completely right, I downloaded a Driver 11 years old and it magically fixed everything. However now when I use apo theres this insane Buzz do you know if that is on APO or just on my Mic and if APO is at fault, is there a VST I can use to fix the buzz?
-
Is it your mic? If so try the following. First, uncheck the checkboxes as shown in the attached screenshot. This ensures that Equalizer APO (being an Audio Processing Object) doesn't get bypassed when Discord tries to use your mic in exclusive mode. Second, that is for your mic and headphones, try all Audio subsystem settings found in Discord. Some have it 'automatic', others on 'legacy'. But you need to try them all.
-
luxbris created ticket #345
it doesnt work on discord
-
where is it
-
Btw. The volume will remain on 1-2%. The gain is increased which makes the sound louder so no worries there.
-
Good to hear. Automatically changing to SFX/MFX is okay. I don't know why the popup still appears but it's nice to know that your volume is a bit better.
-
okay so i set it to device default effects and changed it to sfx/efx & restarted. however, the popup in the second screenshot still shows up and it did automatically change to sfx/mfx. but, it seems to be a bit louder now! the volume still says it's 1-2%, but it sounds better, and games are picking it up more! thank you so much for your help, hopefully there aren't any issues in the future :D
-
In principle an Audio Processing Object (APO = sound enhancement software) isn't a part of an audio device driver so it shouldn't matter what driver to use. But it does happen that a 'bad' driver has trouble with the audio stream provided, in this case, by Equalizer APO's engine (the APO). For example this could be a sample rate conversion issue or simply an audio buffer issue, both causing distortions. Another issue with driver update software that it includes 'settings' for APO's or actual APO's....
-
I’m sure that isn’t the issue. EQ APO worked perfectly before. The problem started after I updated my audio drivers using a third-party app. Since then, EQ APO sounds noticeably worse, even though I’m using the exact same sound configuration as before. I think the driver update may have caused compatibility issues with the audio engine. How can I fix this and restore proper compatibility between the drivers and EQ APO, and If it is an issue with the engine how can I fix it?

-
By turning off enhancements the audio stream isn't going through the sound manipulation engine of Equalizer APO. If the sound from your mic sounds bad then it has to do with this engine and perhaps other enhancements (APO's) working on your mic. In other words, it's either some compatibility issue between APO's or it's this engine itself what causes the issue. Have you add anything in the Configuration Editor on your mic? Could you show your configuration files starting with config.txt?
-
It's all pretty confusing. At least when the pre amp can't be used we know that Equalizer APO isn't working on your mic. And when it went back to LFX/GFX then it can be about something restoring things for this mic device. That could be Windows itself, a piece of software installed with the mic or some overactive anti-malware/firewall app although that isn't very likely. I'm not sure what you can do. 2 things to check and try. First, on the mic properties page check if the 'Audio enhancements' is...

Great! Install 1.2.1 and try it. But it could be that the message keeps on popping up. In that case you need to confirm if Equalizer APO is indeed uninstalled from the "michael yo" device. If not, just use Peace by increasing the pre amp slider. If the mic gain (say volume) is increased then you're done. If it isn't and you're sure that Equalizer APO remains installed on the mic you need to go through all APO techniques available in the "Install as" dropdown box. First pick SFX/EFX and restart your...

Thank you a lot kind man!!!

It is confusing. The 2 error messages are actually about 2 separate things. The first one is with the update checker app of Equalizer APO 1.4.2. The second is an issue of the automatically uninstallation of Equalizer APO on your "michael yo" device. So both need to be addressed differently. So firstly the "This application failed ...." error popup should be dealt with by removing the automatic startup of the update checker. This is a "task" Windows performs at startup. The task need to be removed...
-
i'm really sorry but i'm kind of confused, i've never really done anything like this before. what should i try next? and how exactly should i do it?
-
Looking at the error message I see that the update checker is still in the Windows Task Scheduler. It should have been removed at the uninstallation of version 1.4.2. In your case you need to remove it manually in the Windows Task Scheduler. If you don't know how to, you could download my Equalizer APO issue solver. When run with administrative rights (right click menu -> Run as administrator) it can remove this for you. There's remove button under issue 6. The other popup could be a matter that...
-
Sometimes that isn't enough. In Peace I do: net stop audiosrv net stop audioEndpointBuilder net start audiosrv And when using Peace it's under the button "Restart Windows audio service" on the "Debug and Testing" tab in the settings. But one has to start Peace with administrative rights.

Sometimes Equalizer APO 1.2.1 works or even 1.1.2. I don't know why and the developer probably doesn't know either. But it's worth to try. Note that both versions don't have the Device Selector. In their case its the Configurator in which you manually pick the APO technique. But you're now familiar how to do this. Unfortunately, it also needs a computer restart to invoke any troubleshooting option change. This can be quite annoying when trying many options. I recommend trying SFX/EFX first.
-
the setting already enabled when i tried it, plus i tried disabling it and reenabling it, but it still came up with the same message. i did also individually try all the troubleshooting options, plus disabling the use original apo. do you know where i could find an older/newer one? or anything else that would solve this/let me enhance my mic?
-
And in trying the troubleshooting options you did click the 'Ok' button to invoke a changed option? I guess when it went more quite a new driver has been installed, probably with a Windows update. Perhaps you can find an older or newer one for this Realtek mic device. Unfortunately it can be tricky to find anything good for Realtek devices. Looking at the testing by the Device Selector none of the APO techniques work but that isn't always the case. I guess you have tried them all. It needs what's...

a little while ago, my microphone became really quite out of nowhere (still works, though testing in sound settings the volume appears only ever at around 0-10% when i'm speaking) and after trying everything basic i could find, i decided i just had to download something to boost it. however, when i go to install it on here, it says there is a problem (image attached). anything i could do to fix this? i've tried all the troubleshooting options and none of them seem to work. i'm not sure if this is...
-
Do you mean the Configurator or Device Selector? The Configuration Editor doesn't show the devices status. Anyway, it's a neat trick. Also, when Equalizer APO on devices gets uninstalled by a Windows update usually starting the Device Selector / Configurator fixes that.

Sorry for bumping an old thread. I was looking for an actual fix as I have this issue myself, and I've only "sort-of-solved" this issue by having the Configuration Editor autostart with Windows (by adding the shortcut into shell:startup), and it lets me see the driver status upon startup, for the cost of closing one window if they're working properly; instead of noticing the audio is somewhat off later on.

I don't get it either. It seems to happen in rare occasions but in what occasions I don't know. It seems that dll's of Qt which are just for creating interfaces so the interface of Device Selector and Configuration Editor. Sometimes these dll's flagged as malware and therefore blocked. Perhaps Windows Defender is a bit overactive. At a next update it could be suddenly solved.

They look the same on my computer.

This seems to happen sometimes. It may be that the developer doesn't know why this happens. Maybe during the installation something is going wrong all the time. The folders of Equalizer APO should look like the screenshots. You could verify if this is the case on your computer.

I'm not fond of using AI (llm's). In this case ChatGPT is plain wrong. Equalizer APO like any audio processing object works on USB audio devices. However, some devices like your Fifine AM8 aren't playing nice. This could be due to several issues but not what ChatGPT said in this case.
-
thats already on, i mic wont work because it uses usb, chatgpt said apo doesnt support usb and i should use vb cable, which did not help me

-
Just to be sure that Equalizer APO can't work, uncheck the exclusive mode checkboxes as shown in the attached image. Some recording/streaming apps want to have exclusive access to a mic so no other app is able to record/stream. But that bypasses any Audio Processing Object (read sound enhancement) like Equalizer APO.
-
If you can't get Equalizer APO to work on your mic then VB-Cable by VB-Audio might offer a solution by installing Equalizer APO on this VB-Cable and redirect your mic input through this cable. But I'm not an expert on this. Usually one installs Voicemeeter (also by VB-Audio) and installs and uses Equalizer APO on one of its virtual devices A1 to A5. These devices are fully supported by Equalizer APO, that is when the VoicemeeterClient.exe of Equalizer APO is running. Unfortunely I'm also not an expert...

Smart thinking. I don't know what's going on. Perhaps I can take a look at your configuration files. Could you attach them to your next post? I doubt that I can figure it out but I can give it a try.
-
Are you familiar with the troubleshooting options for an audio device in the Device Selector? These options are accessed by selecting your Fifine AM8 and checking the 'Troubleshooting options' checkboxes. Usually the 2 'Use original APO' checkboxes are greyed out, meaning there aren't any. But if they are available uncheck both and click the 'Ok' button to apply this change. If there still isn't any sound then try the remaining 2 APO techniques available in the 'Install as' dropdown box. Note that...
-
Using the pre amp to make the sound louder is okay only in moderation as it will introduce high 'clipping' at higher values. To prevent this, as it may cause audible distortions, Windows intervenes by reducing the overall sound, in principle by applying a dynamic negative pre amp. So the higher the pre amp you set the more fluctuations you get. But this is better than high distortions through clipping. Generally speaking it's about using the pre amp carefully so the fluctuations aren't audible whilst...

-
The only thing I know is that the sampleRate variable is the value of the current audio process, meaning the process of the current selected device, not the one selected by the device selection command. I guess it depends how the APO (audio engine) of Equalizer APO is handling things. It should be as I explained but it may be more complicated of which I'm not aware of.
-
it works if the txt is directly included inside config.txt. is this expected behaviour? if so, some documentation can help. or it's a bug?
-
I'm not sure what you're saying. Equalizer APO has channels up to 8 which of course for a stereo system only the first 2 can be used. And Equalizer APO supports the creation of virtual channels on which any command can be performed.
