What is HeSuVi?
HeSuVi (Headphone Surround Virtualization) is a powerful Windows application that transforms multi-channel audio (like 7.1 surround sound) into an immersive binaural stereo signal for standard headphones. Working in conjunction with Equalizer APO, HeSuVi creates a spatial audio environment that tricks your brain into perceiving sounds from various directions—all without requiring a physical multi-speaker setup.
Perfect for gaming, movies, and music, HeSuVi brings professional-grade surround sound virtualization to your everyday headphones, making it an essential tool for audiophiles and gamers alike.

How HeSuVi Works
HRIR Technology
HeSuVi uses Head-Related Impulse Responses (HRIRs) - sound profiles recorded from various commercial virtual surround algorithms. These profiles contain spatial information about how sound reaches your ears from different directions.
Convolution Processing
Through Equalizer APO's convolution filter, HeSuVi applies these HRIRs to your audio, transforming a 7.1 input into binaural stereo output that creates the illusion of speakers placed around you.
Binaural Audio
The result is binaural audio that tricks your auditory system into perceiving directional sound, creating an immersive 3D audio experience through just two speakers (your headphones).
Installation Guide
Prerequisites
Equalizer APO must be installed first. HeSuVi works as an extension to Equalizer APO and cannot function without it.
Download Equalizer APODownload HeSuVi
Download the latest version of HeSuVi from SourceForge or the official repository.
Install HeSuVi
Run the HeSuVi installer. The software will automatically detect your Equalizer APO installation and configure itself accordingly.
Select Your Headphones
Launch HeSuVi and select an EQ preset specific to your headphone model from the extensive library. This is crucial for optimal binaural effect.
Choose HRIR Profile
Select your preferred virtualization algorithm (Dolby Atmos, DTS Headphone:X, etc.) and adjust settings to your preference.
Configure Audio Input
For systems without native 7.1 support, install a virtual audio cable (like VB-Cable) to create a virtual 7.1 input that HeSuVi can process.
