Tool usage guide
The Audio Binauralizer converts stereo audio into immersive binaural sound. It supports pseudo-3D stereo widening for a broader soundstage or HRTF-based processing using SOFA files for realistic spatial audio, with adjustable parameters and multiple output formats.
Background
A podcast producer has stereo recordings that sound flat when listened to with headphones.
Problem
The audio lacks spatial immersion, making it less engaging for headphone users.
How to use
Upload the podcast MP3 file, select pseudo-3D mode, set stereo width to 1.5, and output as AAC format.
Outcome
The podcast audio gains a wider soundstage, providing a more immersive experience for listeners.
Background
A game developer needs spatial audio for a virtual reality environment.
Problem
Standard stereo sound effects do not provide accurate 3D positioning in VR.
How to use
Upload WAV sound effects, use HRTF mode with a provided SOFA file, adjust output gain to 3 dB, and export as OGG.
Outcome
The sound effects are binauralized, delivering realistic spatial audio cues in the VR application.
Binaural audio simulates 3D sound perception for headphone listening, creating an immersive spatial experience.
Pseudo-3D uses stereo widening for a wider soundstage, while HRTF uses SOFA files for accurate head-related spatial positioning.
You can upload common audio formats like MP3, WAV, AAC, and others supported by your browser.
Yes, HRTF mode requires a SOFA file containing head-related transfer functions for processing.
Yes, you can set the stereo width from 0.5 to 2 to control the spatial expansion effect.
