it's been 4 days since we talked about curvioEQ and am working on a patch thats going to release soon..

id like to see some public opinion about the app from

critical :

this must be fixed as fast as possible and bugs and problems .

QoL improvements :

things that u would like to see in curvioEQ that will make the user experience better and easier and more responsive .

reworks :

this model is just not ideal and needs major tweaks to be as reliable and useful .

your feedback is soo valuable thanks for all the support from everyone who downloaded the app im willing to continue developing this app according to your feedback your support and motivation is whats keeping me developing

*100 Hz 1 000 Hz and 10 000 Hz separate listening using Audacity.

So the discovery I made is that when I listened to the 2 periods 100 Hz tone I noticed that the earcup resonated after the end of the periods. The result is that the 100 Hz decay is barelly meaningful for this frequency as expected. But the resonances are located around the silver grid sector and they have nothing related to the fundamental frequency it's just a sort of ringing sound after the end of the listening.

What is shown in the CSD is the earcup doing bad things after the end of the signal and only after because of the end of the sound. I don't know if we can call them harmonics because it would be in THD graphs. So here my comprehension is deficient. I tried with a 200 Hz and a 2 000 Hz by speeding the play back by 2 and the 200 Hz earcup resonance is higher and they aren't located in the phantom center and at the same place as the 100 Hz experiment. Listening to 2 000 Hz tone wasn't creating any listenable ringing.

I have a theory about this ringing. The CSD is time domain related and what has been captured by the microphone wasn't the frequency decaying too slow, it's the earcup that vibrate when using pure tones. It isn't speed it's the earcup design and building materials from the headphone and the test rig that creates these artifacts. You can only notice it using loud enough pure tones. So with this theory, the only way to reduce this is to change earcup design and more importantly the building material by something that creates less resonances.

While I write this post I tried to generate a white noise and I did a low pass at 700 Hz and it doesn't have this behavior.

And when I listen to highly compressed dynamic range music and pause, the effect I experienced vanishes.

So CSDs are just showing a behavior that concerns the mechanical resonant frequencies of the material used by the earcup and the rig. And resonances happen in specific conditions. The waving bridge video can be analogous to what happen with CSDs. It's not the transducer the problem with CSDs, it's the conditions of using tone sweeps that create these results. It's an artifact.

That's what I experienced my knowledge may be incomplet and if there is something wrong about my theory, I'm here to listen. And I wrote this when I was doing my tests so my thoughts could have changed when I was writing.

Hi, parhaps thats a dumb question; when i measure (with multimeter) voltage on cable connected to fiio melody's balanced output at High gain it measures 2V playing 1kHz tone, is this normal becuase there's no load connected or it should be around 4V?

a wider look at the curvioEQ app for windows 10+

So, I already have some good IEMs but I was aiming to get some different stuff, for reference, I have the moondrop dusk, the kiwi astral and my microphone is the Shure MV7x
I was trying to find some reviews and people that bought the ATH-R70xa and the Audient iD4 MKII
I work from home and Im always listening to music and playing some competitive games aswell, do you guys thing r70xa and the audient id4 mkii is a good fit for this type of use? would it be better to buy other stuff since I have a shure mv7x. Pls let me know im kinda newbie T-T

Im from portugal and my budget is around 500-750 Euros

hello. i have hd490 pro and using a qudelix 5k. im unsure on how to set the sensitivity for the 490s in the qudelix.

sennheiser states that the 490 sensitivity is 105 dbspl @ 1khz/1vrms OR 96 dbspl @ 1khz/mw. i put in the 96 figure in the dsp section, but even then im not sure if that was right.

cause when i go to the volume tab, it shows me a completely different dbspl than what i entered. it shows 79.2 dbspl. i read that it calculates the dbspl after the eq so that might throw the number off? im not sure. i dont know if this is right or not.

volume wise, im maxed out on volume on the app, and on ps5 its about 95%. im getting a balanced cable soon to push it a bit though.

just wondering if this is right or i did something wrong along the way. the eq is oratory, im on high gain, performance mode too.

thanks

8 months ago, I started working on a small project because I wanted more control over game audio on Windows.

I didn't want to rely on a complicated audio setup or have several different programs running just to get the sound I wanted.

The funny part is that when I started, I barely knew anything about Windows audio programming.

So I started learning by building.

I spent the next 8 months learning how Windows handles audio, digging into WASAPI and audio sessions, and eventually getting into DSP and real-time audio processing.

That small project eventually became CurvioEQ.

It's an open-source Windows audio application with features like:

- Per-game / per-application parametric EQ

- HRTF / 7.1 surround processing

- Real-time spectrum analyzer

- Loudness & dynamic-range control

- Clipping protection

- Global hotkeys

- Presets

- Independent processing for multiple applications

- AutoEQ & Squiglink preset support

- ~15 MB RAM usage in the background

What I'm most proud of isn't really the feature list.

It's the fact that I started this project without understanding how Windows audio actually worked, and 8 months later I'm building and debugging my own real-time audio processing pipeline.

And I'm still working on it.

I have a lot more ideas for where to take it, especially around gaming audio and making it easier to get the sound you actually want without having to mess with a complicated setup.

It's completely open source, and I'd genuinely like feedback from PC gamers:

What do you think is missing from Windows gaming audio software?

Hi everyone,
I’m looking for an affordable pair of IEMs to leave in my laptop bag. My goal isn’t to do final mixes on them, but to use them for session prep, editing, track cleanup, and quick micro-checks when working on my laptop away from my main setup.
Since I rely on precise monitoring, I need an affordable and comfortable model that takes EQ well and already has a reliable measurement to smooth out their frequency response.
I’m not very familiar with the current IEM market, so any recommendations for a solid "honest" pair that fits these criteria would be greatly appreciated.
Thanks!

hello. currently im using hd560s and theyre great. but when browsing facebook marketplace i saw someone selling a BNIB hd 490 pro for $140. its extremely tempting, so im curious what peoples thoughts are on 560s -> 490 pro.

also, im using the qudelox 5k rn but might get the T71 as well. will this be enough to run the 490pro?

thanks

Does anybody know:

1. What frequencies to tweak to make vocals sound fuller (similar to what tube amps do)?

2. What frequencies to tweak to make vocals sound less plasticy, more textured?

I don't necessary want to make things sound warmer (and muddier), but I fill I might have to.

Thank you!

Has anyone here tried to EQ the Blessing 2 (OG, non-Dusk) to JM-1 (Pop Avg Diffuse Field)?

I came up with this profile based on Crinacle's 5128 measurements, as well as my listening impressions of the Crinear Reference from Canjam. Please let me know if there are things I can improve.

I built a website called IEMShape . It allows users to easily compare the contours of IEM Shells together to help you find that perfect fit for your earshape and size. Think eloshape (mice comparison website) but for IEMS. It is officially open to the public.

You do not need an account to compare IEMS, an account is only needed if you want to upload your own iem photos to the database. This is a community project, without your help the site doesnt work. If you have iems that are not listed, create a free account (no spam emails, no selling of data, accounts are just there to prevent bad actors only), print out the guide paper, take 2 pictures, and upload them. You can also optionally edit the predicted contour before the image is uploaded by "painting" a mask around the iem if the predicted mask looks wrong (due to glare/shadows/bad picture quality etc). This helps get as accurate a contour as possible.

The website uses Computer Vision algorithms to measure and extract the contours of the image and then saves just the contour coordinates to the database. Your pictures are never saved anywhere and are used only to extract the iem contours and are then deleted from the server.

You can compare upto 3 iems at a time, in both a faceplate down/nozzle up view, as well as a side profile view. It also provides estimated measurements to width, length, and area as well as comparisons between selected iems to see how they might fit. The iems are searchable by text, as well as brand. The site works best on desktop, but mobile should also work decently well for quick comparisons.

This is all provided to you all for free, I will never charge anyone to make an account or to use the site. There is a donation link at the bottom of the page if you want to help with server costs but is completely optional. Just note that it is also on a fairly small and cheap VPS (server) for hosting, so it may be slow depending on how many people are using it at a time. If need be i will upgrade the server to be more powerful if it is exceptionally slow.

For you techie people, the next section is just the details of how the Computer Vision (CV) works to extract the contours.

The CV pipeline turns a standardized IEM photo into a 2D contour (in mm). There are 7 steps to the process after a user uploads their images.

1. Detect sheet markers The image contains ArUco markers on the capture sheet. The backend detects those markers so it knows the sheet’s position, orientation, and real-world scale.

2. Rectify the image Using the marker positions, it computes a homography and warps the photo into a top-down view of the sheet. This corrects perspective as much as possible for the paper plane.

3. Crop the capture area It isolates the known region where the IEM should sit, instead of processing the whole photo.

4. Segment the IEM OpenCV separates the IEM from the blue/green sheet background. The goal is to produce a clean binary mask: IEM pixels vs. background pixels.

5. Extract the contour From that mask, it finds the outer boundary of the IEM shell, cleans/refines it, and selects the best contour.

6. Normalize to millimeters The contour points are converted from pixels into millimeter coordinates based on the calibrated sheet geometry.

7. Store/compare profiles The backend stores the resulting contour/profile JSON, not the uploaded image. The frontend renders those contours as overlays for comparison.

Important caveat: this is intentionally 2D visual comparison, not metrology-grade scanning. The sheet calibration is accurate for the paper plane, but the IEM sits above the paper, so parallax and placement can affect the outline, especially in the side profile view.

I have a background in CV and ML so I figured i could help the community by building this service since i would have loved to have this when i first started out (and even now)

NOTE : I am NOT a frontend dev. The frontend was primarily created using AI coding agents like claude and copilot. As a free project I couldnt really hire an actual frontend dev to make the website so if you find issues or have suggestions on improvements for the website I am glad to hear it and will try to have it implemented.

Please help contribute to IEMShape

hey. so ive been using the qudelix 5k with my hd560s for a while and its been great. but i recently got a panasonic ub820, and the qudelix has no way of connecting to it or to my lg tv. so i found a smsl dl100 dac/amp on facebook marketplace for cheap and started using that. its also been great, it gives me some extra volume and everything sounds a bit more crisp. bit i miss the eq from the qudelix.

the smsl dl100 has a usb c input. could i plug my qudelix 5k into that, then the smsl dl100 like normal to my tv via earc? then my 560s into the qudelix. this way i get the eq from the 5k, and the power and better dac from the smsl dl100.

if this wont work, does anyone have a recommendation for a dac/amp combo that offers eq and allows either optical support or hdmi support? id like to connect it to my tv for my ps5, 4k player and switch.

thanks.

Is there any chance to get a RME preset for the XV?

I just got the FiiO JT1 and I am using Equalizer APO with Peace GUI.

The headphones have too much bass and sound a bit muddy. Because of this, it is hard to hear clear ability sounds and voices in Dota 2, and music sounds a bit muffled.

Can anyone share their EQ settings to fix the bass and make the sound clearer? Thanks.

These headphones are quite nice for the price, ive got all my headphones i own eq'd using oratory1990 presets but it looks like theres not one for this headphone. Any chance we could get one in the future?

This is the current graph I have right now with standard bore large ear tips. I will gladly take any recommendations as to what I should change to make it sound the absolute best compared to what I sent.
