Audio Spatializer by 8Dfy — harsh

Audio Spatializer by 8Dfy transforms flat YouTube audio into an immersive 8D spatial experience using real-time Web Audio processing.

Unlike pre-made "8D audio" videos, it works on ANY YouTube video and uses real psychoacoustic techniques: interaural time delay, head shadow filtering, convolution reverb, and non-linear panning curves.

Features:

4 spatial modes: Standard 8D, Multi-band Surround, HRTF 3D Positioning, Binaural Beats
18 curated presets with sub-variants (Warm, Deep, Punchy, Intimate, Grand, Cathedral)
Bass enhancement (sub-bass 45Hz + low-shelf 80Hz, up to +14dB)
Clarity EQ (presence 3.5kHz + air 10kHz)
Convolution reverb with synthetic impulse response
Binaural beats for Focus (20Hz), Relax (10Hz), Sleep (2Hz), Meditate (6Hz)
Audio export as WAV (lossless) or WebM (PRO)
Draggable floating control panel with real-time pan visualizer
Strength slider to blend preset variants from subtle to extreme
100% client-side — no audio leaves your browser, no data collected
Free: Full 8D audio on YouTube with 8 presets, bass/clarity/reverb controls, and visualizer.
Pro ($4.99 one-time): Surround, HRTF 3D, binaural beats, audio export.
