True 7.1 Surround on Any Headphones
HeSuVi turns standard stereo headphones into a full 7.1 surround system. It uses real HRIR profiles from Dolby Atmos, DTS Headphone:X, Windows Sonic, and a dozen other surround engines.
What Is HeSuVi?
A free Windows tool that brings real 7.1 surround sound to any pair of headphones, powered by the same HRIR profiles used in commercial spatial audio engines.
Surround sound without the speakers
HeSuVi (Headphone Surround Virtualization) takes 7.1-channel audio and converts it into binaural stereo that your brain interprets as spatial sound. The result: positional audio through regular headphones, whether you are gaming, watching movies, or mixing music. It works by loading Head-Related Impulse Response (HRIR) profiles and applying them through Equalizer APO‘s convolution engine.
What makes HeSuVi different from basic virtual surround is its library of HRIR profiles. You get access to profiles from Dolby Atmos for Headphones, DTS Headphone:X, Creative SBX Pro Studio, Sennheiser GSX, Windows Sonic, and over a dozen other systems. These are the same spatial audio algorithms sold commercially for $15-$20, available here at no cost. You can switch between them instantly and compare which profile sounds best with your particular headphones.
Built-in headphone EQ
HeSuVi includes a graphic equalizer with over 1,000 headphone-specific correction presets sourced from AutoEq, oratory1990, and Innerfidelity measurements. Pick your headphone model from the list, and HeSuVi flattens the frequency response before applying spatialization. This matters because HRIR accuracy depends on a neutral frequency curve. Without correction, bass-heavy headphones tend to sound muddy with surround virtualization, while bright headphones can get fatiguing.
Who built it and who is it for
Developed by jak33 and hosted on SourceForge since 2018, HeSuVi is a Free Pascal application that runs on Windows 7 through Windows 11. It pulls roughly 8,000 downloads per week and carries a 5-out-of-5 rating on SourceForge. The tool is popular with competitive FPS gamers who need accurate positional audio, home theater enthusiasts watching 7.1 content through headphones, and audiophiles curious about different spatial rendering approaches. It requires Equalizer APO as a prerequisite, which handles the low-level audio processing.

What Makes HeSuVi Different
HeSuVi packs the surround engines of commercial products into one free tool. Pick your HRIR, correct your headphone response, and fine-tune speaker placement — all without spending a cent.
Multi-HRIR Virtualization
Switch between Dolby Atmos, DTS Headphone:X, SBX Pro Studio, Sennheiser GSX, Windows Sonic, and more. Each profile was captured from real hardware, so you get genuine spatial cues instead of generic DSP effects.
1000+ Headphone EQ Presets
Built-in correction curves from oratory1990, Innerfidelity, and Headphone.com databases. Select your exact headphone model and HeSuVi flattens its frequency response before applying surround, so the spatial image stays accurate.
Speaker Position Adjustment
Drag individual virtual speakers around a 7.1 layout. Move the front-left closer, widen the rears, pull the center channel forward. Your spatial stage, your rules.
Stereo and 5.1 Upmix
Not everything ships as 7.1. HeSuVi upmixes stereo or 5.1 content to fill all eight channels before virtualizing, so older music and movies still get full spatial treatment.
Profile Management
Save separate configs for gaming, movies, and music. Each profile stores the HRIR, EQ curve, speaker positions, and crossfeed settings. Hotkey switching lets you jump between them mid-session.
Crossfeed Blending
Strict left/right separation causes listener fatigue on headphones. Crossfeed bleeds a small amount of each channel into the opposite ear, mimicking how real speakers behave in a room.
Multi-Device Support
Run HeSuVi on more than one audio device at the same time. Assign different EQ toggles per device, so your USB headset and your DAC each get their own correction profile.
Volume Optimization
Convolution filters can push peaks above 0 dBFS. HeSuVi analyzes the output in real time and applies clipping protection, keeping loudness consistent without the distortion you would hear from a simple limiter.
Channel Swap (L/R)
Wear your headphones backwards by accident? Or dealing with a cable that reverses channels? One toggle swaps left and right without re-plugging anything.
Portable with One-Click Updates
No installer, no registry entries. Drop the folder anywhere and run it. When a new version appears, HeSuVi downloads and applies the update from inside the app itself.
HeSuVi runs on top of Equalizer APO and supports sample rates of 44.1 kHz and 48 kHz.

Getting Started with HeSuVi
Everything you need to turn your regular headphones into a full 7.1 surround system. This guide covers the complete setup from first download to your first listening session.
Downloading HeSuVi
HeSuVi requires two pieces of software: Equalizer APO (the audio engine) and HeSuVi itself (the surround virtualization GUI). Both are free. You also need VB-Cable if your sound card does not natively support 7.1 output – most built-in sound cards fall into this category, so grab VB-Cable to be safe.
Head to our download section above to get all three files. The HeSuVi installer is about 27.3 MB and comes as a single .exe file (HeSuVi_2.0.0.1.exe). Equalizer APO is around 8 MB, and VB-Cable is roughly 1 MB. On a standard broadband connection, all three downloads finish in under a minute.
Only a Windows version exists. HeSuVi supports Windows 7 through Windows 11, both 32-bit and 64-bit. If you are on 64-bit Windows (most systems sold after 2010), download EqualizerAPO64-1.2.exe. For 32-bit, use the regular EqualizerAPO-1.2.exe. HeSuVi itself is a single universal build that works on both architectures.
There is no beta or nightly channel for HeSuVi. Version 2.0.0.1 from January 2019 is the current stable release and the only one available. It works well on Windows 11 despite the age of the release.
Installation Walkthrough
Install the three components in this exact order: VB-Cable first, then Equalizer APO, then HeSuVi. Skipping this order causes problems because Equalizer APO needs to detect VB-Cable during its setup, and HeSuVi needs to install into Equalizer APO’s directory.
Step 2a: Install VB-Cable. Extract the VB-Cable zip file and right-click VBCABLE_Setup_x64.exe (or VBCABLE_Setup.exe for 32-bit). Select Run as administrator. Click Install Driver in the window that appears. You will see “Installation Complete and Successful!” – click OK. Reboot your PC before continuing.
Step 2b: Install Equalizer APO. Run the Equalizer APO installer. The setup wizard walks you through a standard Next > Next > Install sequence. The key moment comes at the Configurator window after installation finishes. This screen lists every audio device on your system.
In the Configurator, find CABLE Input (listed under VB-Audio Virtual Cable) and tick the checkbox next to it. The Status column should show “Default device, APO can be installed.” You can also check your actual headphone device if you want EQ on it later. Click OK when done. Do not reboot yet.
Step 2c: Install HeSuVi. Run HeSuVi_2.0.0.1.exe. The installer asks where to unpack – point it to the Equalizer APO installation directory, typically C:\Program Files\EqualizerAPO. HeSuVi extracts itself and launches the GUI automatically.
After HeSuVi launches, go to Actions > Restart Audio Service in the menu bar. This activates Equalizer APO without requiring a full system reboot. If audio stops working or sounds distorted at any point, use this same menu option to reset things.
Initial Setup & Configuration
With all three programs installed, you need to configure Windows audio routing so surround sound flows through VB-Cable into HeSuVi and out to your headphones.
Set CABLE Input as your default playback device. Open Windows Sound settings (right-click the speaker icon in the taskbar > Sounds, or use HeSuVi’s Actions > Open Windows Sound Panel). In the Playback tab, right-click CABLE Input and select Set as Default Device. Then right-click it again, select Properties > Advanced, and set the Default Format to 24 bit, 48000 Hz (Studio Quality).
Configure CABLE Input for 7.1 surround. Still on CABLE Input, click Configure at the bottom-left of the Sound panel. Select 7.1 Surround and click through the wizard. This tells Windows to send 8-channel audio to VB-Cable, which Equalizer APO then processes.
Route audio to your headphones via CABLE Output. Switch to the Recording tab, right-click CABLE Output, and choose Properties. Go to the Listen tab, check Listen to this device, and select your actual headphones or sound card from the dropdown. Click Apply. Audio now flows: Windows apps > CABLE Input (7.1) > Equalizer APO + HeSuVi (processing) > CABLE Output > your headphones (stereo).
Your First Surround Session
Open HeSuVi and look at the Virtualization tab. On the left, you see the Common HRIRs list with files like dolby_atmos.wav, dts_hpx.wav, sbx33.wav, and sonic.wav. Each file is a different surround sound algorithm. Click one to select it – HeSuVi applies the change instantly with no restart needed.
Here is a quick rundown of the most popular profiles and what they sound like:
- sbx33.wav or sbx100-.wav – Creative SBX Pro Studio. Wide soundstage, good for gaming. One of the community favorites.
- dolby_atmos.wav – Dolby Atmos for Headphones profile. Natural-sounding with accurate positioning. Good all-rounder.
- dts_hpx.wav – DTS Headphone:X. Punchy bass, immersive for movies.
- sonic.wav – Windows Sonic. Subtle and clean. Works well for music.
- gsx+.wav – Sennheiser GSX. Tight imaging, preferred by competitive FPS players.
To test if surround is working, click the 7.1 Test button in the Speaker Position Adjustment area. You should hear a tone rotating around your head through all eight channels. If the tone only plays in left and right, your Windows audio is not set to 7.1 – go back to the Sound panel and re-run the Configure wizard on CABLE Input.
The Speaker Position Adjustment panel shows FL, FC, FR, SL, SR, RL, RR nodes around a headphone icon. You can drag the sliders to move virtual speaker positions closer or further from your head. Most people leave these at default, but if surround feels too wide or narrow, try pulling the side speakers (SL/SR) inward.
The Volume Adjustment sliders on the right let you control Master, Center, Front, Side, Rear, and LFE (subwoofer) levels independently. If dialogue sounds quiet in movies, bump up the Center channel by 10-20%. If explosions are too bass-heavy, lower the LFE channel.
Once you find a combination you like, go to the Additional tab and use the Profile Manager to save your setup. Click Save, give it a name like “Gaming” or “Movies,” and you can switch between profiles later with a single click.
Tips, Tricks & Best Practices
Use the Equalizer tab for headphone correction. HeSuVi includes over 1,000 headphone EQ presets from oratory1990 and AutoEQ. Go to the Equalizer tab, click the dropdown, and search for your headphone model. This flattens your headphone’s frequency response before the surround processing kicks in, which makes the spatial effect more accurate. If your specific model is not listed, try one from the same manufacturer.
Avoid stacking EQ tools. If you also use Peace Equalizer or another Equalizer APO frontend, be careful about running both simultaneously. HeSuVi writes its own configuration to Equalizer APO’s config file. Reddit users on r/headphones generally recommend using Peace for pure EQ tasks and HeSuVi only for surround virtualization – not both EQ panels at once.
Common mistake: forgetting to switch back. CABLE Input stays as your default device even after you close HeSuVi. If you stop hearing audio after a reboot, check that CABLE Input is still the default and that the “Listen to this device” option on CABLE Output is still enabled. Some Windows updates reset these.
Crossfeed for stereo music. The Additional tab has crossfeed settings that blend a small amount of the left channel into the right and vice versa. This makes stereo music (which was mixed for speakers) sound more natural on headphones. Set the crossfeed value between 5 and 15 for a subtle effect.
Where to get help. The HeSuVi Wiki on SourceForge has the official setup guide. Reddit’s r/headphones community is active and has a pinned FAQ that covers HeSuVi. For troubleshooting, the SourceForge discussion forum is where the developer (jak33) sometimes responds directly.
