YouTube is full of videos on setting up Windows audio, Voicemeeter and VSTHost. All you need to remember is: do not select ASIO, WDM/KS or WASAPI Exclusive mode drivers as output device in VSTHost because of these devices bypasses APO layer.

You need a VAC (VB-Audio Voicemeeter as for an example (I've used BANANA version). Set the VAC as default playback device through system audio options. Take the VAC as input in VSTHost and select device which supports APO layer in VSTHost outout settings. As APO's are in playback you can't use ASIO/WASAPI Excluaive nor WDM/KS as output device in VAC). I have left Windows behind so can't give closer instructions.

At least you now know how to properly select a device for the other commands. It's a very important piece of knowledge when working with Equalizer APO. Not using a device selection means that commands are performed on all devices including the microphones. Unfortunately getting VST plugins to work is a matter of trial and error. As the Instalooper UI isn't crashing that's nice but it doesn't mean that it's compatible with Equalizer APO as you have noticed. But be sure that Equalizer APO is working...

Yes, usually it is. But there have been some posts here on this forum saying that on Windows 11 restarting the audio service doesn't always seem to work. To avoid this issue, in the Peace equalizer I not only stop "audiosrv" but also "audioEndpointBuilder". After starting "audiosrv" "audioEndpointBuilder" is automatically started also. So I guess this should be included in the implementation you're requesting. However, the developer isn't very active so your request won't be implemented any time...

I did as you've stated with selecting the device and now the Instalooper UI opens but no sound when I press any of it's buttons. Other plugins are working but they are not working right. So i guess last option will be to use the vst host but I can't find instructions on how to use it with APO.

Yes, it's confusing when talking about audio devices and their selection in Equalizer APO. So I've attached 2 images that shows how to do it properly. Of course in principle a DAW is also a VST host. But I meant a VST plugin which in itself is a VST host. This VST host plugin is then be loaded into Equalizer APO in the Configuration Editor.

I guess you have selected the device from the top downdrop list. That doesn't work. First forget this top dropdown list altogether. For manipulating the sound of a device you have to add a device selection command. Then below this command you do your audio manipulating stuff like filtering and VST plugins. In case of your example this device selection command must be before the pre amp command. If you open a VST plugin panel and it crashes, this suggests that the VST plugin isn't compatible with...

Hi Mike, I'm doing okay. Everything fine at your side? After Equalizer APO is installed on the Windows internal sound card (motherboard audio chip?) you can add some VST plugins to add some reverbs and delays. Btw. a simple time delay can also be done with the Equalizer APO delay command. For instance, VSTPlugin: Library GGate.dll Thresh 0.289969 Fade 0.393939 Attack 0.0666667 which is a gate effect plugin, usually used to filter the noise of a mic. I've added this plugin with aid of the Configuration...

It's a known issue. Or better said it's a limit caused how VST plugins are implemented. The interface you're seeing and using isn't the actual VST plugin that processes the audio. The Configuration Editor shows only the interface part of the plugin whilst the Equalizer APO audio engine (equalizerapo.dll) has the audio processing part of the plugin loaded for changing the audio. In principle this part could be shown for the live signal level. But having 2 interfaces on screen can be more confusing....

Hi, I'm on Windows 11. Equalizer APO is able to process the audio normally, and adding some VST plugins allows the audio to be processed through them. However, I've noticed that the level meters that are supposed to show the live signal level are not working. I have tried this with two ReaPlugs and TDR Nova. Is there a known issue regarding this? Thanks!

I don't quite understand what you're asking. The Configuration Editor just gets from the audio device driver the number of available channels (speakers). This may change if atmos is switched on. Anyway, each speaker or a set of speakers can be equalized separately by using the Channel command of Equalizer APO.

I found an awesome speaker calibration program that I got to work great with a 5.1 setup. The dolby access app just updated and now converts stereo and 5.1 to atmos. Does equalizer support height speakers or would i have to apply the heigh calibrations to the surround speakers and change it to 7.1? In configuration editor when atmos is enabled it says the current speaker setup is 7.1.

That's just great. Perhaps finetune it a bit by looking at the graph in the analysis panel. The Q(uality) value determines the bandwidth of the peak filter. The higher the Q, the narrower the peak.

These biquad filters are under the Parametric filters menu (green plus button). Unfortunately the peak filters aren't represented as the Graphic EQ is (in Peace they are of course as it uses sliders). So having a lot of adjustment points doesn't make it easy to replicate the EQ using peak filters. But biquad filters are without any issues (and much faster although this isn't important). I don't have any good solutions to offer as we don't know the cause. Perhaps less adjustment points will do the...

Hi Peter, Thanks for the reply! I don't use and haven't used Peace, and I can't see any biquad filters in vanilla EAPO. My Graphic EQ is quite convoluted, with a lot of adjustments.

There are some issues with Graphic EQ of which the developer hasn't commented. They are there since the beginning and will not by resolved any time soon. I usually advise to not use Graphic EQ and use the parametric (biquad) filters instead. Simply due to the buzzing/popping/crackling issue of Graphic EQ the Peace equalizer uses peak filters as default. Btw. Having EFX/SFX is a good thing to try on Windows 10 and 11 as this is their way of doing Audio Processing Objects (APO's). But some older device...

I can imagine it's annoying that you can't find an easy fix. I also saw some post here on this forum saying that an empty having or adding HKEY_LOCAL_MACHINE\SOFTWARE\EqualizerAPO\Child APOs key did the trick. I don't know why but it is suggested by the developer at least once. I only know that this key is used to back up the audio device routings before the Configurator reroutes the audio streams.

Here on SourceForge you can get my bug removal tool which solves the issue of the crashing of the Configuration Editor at its startup. This crashing is caused after detaching the analysis panel (the lower graph window) from the editor. The crash of the Configuration Editor is solved by deleting the 'windowState' value from the 'HKEY_CURRENT_USER\SOFTWARE\EqualizerAPO\Configuration Editor' registry key. You could do this yourself but my bug removal tool will do this for you.

As an addition, if your sub has no separate signal feed then it's hard to implement well because of no control over HW crossover. Those eighth LP and HP filters can be done using EqualizerAPO Filter: commands but you better use cascading technique which means you change Q value for every stage. You can calculate those Q values here: https://www.earlevel.com/main/2016/09/29/cascading-filters/ An example of calculating 96dB/oct 2-way crossover (crossover frequency at 1kHz): Filter: ON LPQ Fc 1000 Hz...

That was just an example of how you have control over each channel with EqualizerAPO. If you don't do crossover through EqualizerAPO then probably you could do this through virtual crossover system where frequency range is split to as many sections as needed (two-way, three-way, ...), but , would it be good system because of 'bleeding' between sections, which means that you get same audio normally and delayed ... which does not sound good. You would need very steep filters for splitting the range...

You can delay channel ... . If you wan to delay sub channel only, it's easy: #Channel: All # filtering if needed #Channel: L R # filtering if needed Channel: <sub channel number> # cut frequencies outside Sub's frequency limits (example) Filter: ON HP Fc 20 Hz Filter: ON LP Fc 300.0 Hz # delay channel (example) https://tinyurl.com/2p9f7prm Delay: 10 ms Channel: All # filtering if needed

Can EAPO set a delay over a frequency range? I'm trying to integrate my sub, and my AVR isn't up to snuff: I have no control over each channel. Furthermore, the sub is insufficiently exact. I'm thinking, that I can set a delay to all frequencies less than the crossover, which should result in better integration. I was hoping a convolution filter might be able to do this, but it seems not. Is such a delay feasible? Is it already implemented, and I simply can't find it? Thanks for the excellent work...

Yes, it must be VoiceMeeter or the "connection" between Equalizer APO and VoiceMeeter. I did have much distortion when using the virtual devices A1 to A5. Fortunately I'm not depending on VoiceMeeter like a YouTuber may be so I simply stop using VoiceMeeter. I tried using the same sample frequency for the speaker audio device. So that the sample frequency on the audio panel of the speaker device the same as the one in VoiceMeeter. But it didn't seem to do the job. Next I increased the sample buffer...

So after some more listening, it seems like the pops are still there, although the amount of them seems to have decreased. To be honest i'm not sure how to fix it. I tried using parametric only (disabling all graphic eq and convolution), and i still seem to get them. So this leads me to think maybe it is not eqAPO and something else in my sound chain. Maybe it is a voicemeeter fault?

Perhaps it is. I don't really know how things are programmed or compiled. Changing the usage of cores would indeed be an interesting test. As the biquad filters (peak, etc.) are ultra fast, it's a rather simple calculation, convolution is more CPU consuming. But still it's quite fast so there shouldn't really be pops and cracks on our fast computers of today. So the only thing I can come up with is that a task gets somehow divided on multiple threads, not on purpose but by "accident". If these are...

That's very interesting... Maybe it has something to do with the audio engine using the threaded virtual cores instead of the logical cores? Maybe the virtual threads do not perform as well as the logical cores, so when it is enabled eqAPO uses essentially less powerful cores? If there was a way to force it to use a specific core(s) that could be an interesting test.

Thanks for this info. I can now offer more solutions to this issue. About the CPU, someone here on the forum reported that his multithreaded CPU was the problem or the problem on his computer. After switching off multihreading in the BIOS the cracks disappeared. This seems to suggest that somehow the processing of convolution is done on multiple threads. But this isn't what the programming code is saying, I believe (I'm not a C++ expert). To summarize there are now 3 solutions for GraphicEQ related...

Yeah, I didn't realise the EQs had different performance until now. So as i have two audio chains (speakers A1 and headphones A2), i decided to make both as optimised/performant as possible. Switching the A1 speakers to parametric was easy as its a very simple (two frequencies) EQ. Maybe that offloaded some of the work of the CPU. Looks like if you want graphic EQ to work without too many issues with voicemeeter, try and keep CPU usage of eqAPO as low as possible. It seems that eqAPO was trying to...

graphic EQ to parametric EQ Parametric EQ is based on peak filters. In all the 8 years I'm supporting Equalizer APO and developing/supporting the popular Peace interface, these kind of filters don't have any issues. Using the channel command is alright but this only has an impact when using Graphic EQ. The biquad filters like peak filters are just too fast to have issues. But when using the virtual devices A1 to A5 of VoiceMeeter and applying some equalization on either of them may come with their...

Based on my limited testing for about an hour, I haven't been able to come across any pops using both the graphic EQ or convolution wav file. This could be due to multiple tweaks I did, however time will tell. The first thing i did is moved my much simpler eq (only eq'ing 2-3 frequencies) for my main speakers from graphic EQ to parametric EQ, maybe this puts less stress on the system? The second thing i did, which i suspect has the most impact, is apply the eq(s) to only two channels using the channel...

I've used VIBE to generate a wav file at 96khz (my sample rate) so i'll give it a shot and post back with my results in a few days!

Good thinking :) It might work so it's worthwhile trying it. Internally the same processing is used but the creation of the convolution file of a GraphicEQ command differs. In that sense using the Convolution command is an easier internal process for Equalizer APO so perhaps it comes without the pops.

Say if i exported the graphic EQ into a wav file using VIBE, and then imported into eqAPO as convolution, would i still have the same issues as it is using convolution?

Unfortunately the last couple of years the developer isn't very active so don't expect a fix. For years in a row I'm doing the most support on Equalizer APO. Even I don't know what's wrong with GraphicEQ (convolution). I have some vague ideas but nothing concrete.

Alright I'll give parametric a shot. Is there any reason why graphic EQ is buggy? Are there any planned fixes?

I guess by taking the parametric EQ (peak filters). Btw. peak filters is what the Peace equalizer uses for its EQ sliders, just to avoid the GraphicEQ issues (although it's possible to switch between by 1 single click).

yes it is only graphic eq. is there any way to fix it rather than switch filter? i use AutoEQ for headphones, and they generate a graphic eq file that i load in.

Reading up on the paper I understand what you want to achieve. As the paper said there are several approaches where any approach must fall in the capabilities of Equalizer APO. Anyway, I don't know how to achieve decorrelation but it seems to me that any approach may be worth while. One could say it's a matter of taste also. So how is your approach? Any auditory satisfying results? I know that using tiny delays can have quite large impacts on the perceiving of audio. Such "tricks" I'm using on the...

I suspect Genelec uses a decorrelation filter in their W371A (https://www.genelec.com/w371a) to accomplish what Earl Geddes and Todd Welti accomplish in their multi-sub strategies. Unfortunately, I don't know the details of how Genelec does it. Wish I knew a teacher in the audio lab at Aalto University in Finland. I'm sure they have a good idea how Genelec does it. The closest I got was browsing this paper by Elliot Kermit-Canfield and Jonathan Abel from Stanford University. That's the reason I kept...

I don't know either. I've no knowledge on this subject. But you're right by just trying it. It just might be a decorrelation filter or an approximate one. If it works I might put it in Peace :)

Thank you, I tried EAPO's convolver. Later, I also tried modifying a reverb effect generated by Peace Equalizer. The PE reverb effect had constant time delay changes: 50 ms, 100 ms, 150 ms, 200 ms, etc. I adjusted the delays from the Peace Equalizer reverb in an ignorant attempt to "decorrleate" them (adjusted the delays to change by unequal amounts). I did not adjust the level summation changes between subwoofer variables. Those are the same as the original PE reverb commands. I don't know if this...

Yes, that did work. I just didn't understand how to properly assign it. Thank you.

There isn't such a filter in Equalizer APO. It has biquad filters and convolution. But the latter may be used for this decorrelation. Convolution is often used for reverb effects. In case of Equalizer APO it's used by its GraphicEQ command to equalize but also it's available as a command for which you can select an impulse response file, for instance a reverb of a concert hall.

It's quite simple. LFX/GFX is the Windows 7 way of doing Audio Processing Objects (APO's as in Equalizer APO). SFX/EFX and SFX/MFX is the Windows 10 (and 11) way. And usually SFX/EFX is the one that gets Equalizer APO going. But sometimes LFX/GFX could still work when it's included in an audio device driver. As a matter affect in some Windows 11 updates Microsoft reverted temporarly back to the old LFX/GFX. A sign that Windows 11 is still in development. As for explaining this you could read up on...

I want to apply a reverb effect to a subwoofer channel using the convolver command. The wiki documentation gives an example: Convolve with a recorded impulse response for a reverberation effect Convolution: church.wav I don't understand how to apply that to a single channel. Thanks.

Background on setup: Output 1: Nvidia GPU to HDMI to AVR (5.1 speakers) Output 2: Motherboard's onboard (backpanel) 3.5mm TRS to amplifier (buttkicker tactile effects) I recently upgraded my PC including motherboard/CPU/GPU and went from Win7 to Win10 but the output setup above remained the same. On my old PC EqAPO worked on both outputs with zero fuss. After the upgrade output 1 worked just fine but EqAPO was having no effect on the sound from output 2 (setting 'preamp: -90.0dB' is my quick way...

How do I apply a decorellation filter in Equalizer APO? Once I have it I will only apply it to the subwoofer channel. The goal is to use decorellation to flatten low frequency room response similar to a multiple subwoofer configuration described by Earl Geddes and Todd Welti. Early Geddes described the application this way, "Then I discovered that this type of filter has a very precise definition and usage - it is called a DECORRELATION FILTER.

What Equalizer APO commands are you using? If GraphicEQ then try to use peak filters instead. GraphicEQ may have some issues sometimes.

Anyone know of a fix for the random pops when audio is playing or being adjusted rapidly? It happens occasionally depending on what song is playing, but is very random and unpredictable, not sure what is causing the random pops. They are quiet pops that aren't really that noticeable but still fairly annoying (much more noticeable on headphones). I'm using eqAPO with Voicemeeter Potato (apo installed on A1,A2). Voicemeeter is going to my UMC204HD @ 96khz @ 256sample (ASIO). Ive tried changing the...
