Explore 6 mind-bending auditory illusions powered by the Web Audio API. From phantom imaging to infinite tones—discover how your brain processes sound.
Create phantom sound sources by delaying one channel 0–30ms. Your brain localizes the sound to the earlier arrival, creating the illusion of stereo imaging.
Manipulate the perceived width of the stereo field. From collapsed mono to expansive wide stereo—control the spatial dimension of sound.
Simulate depth using volume, frequency absorption, and room reflections. Far sounds are quieter, muffled, and reverberant.
Add analog character through harmonic saturation and frequency tilt. Recreate the "warmth" of vintage gear digitally.
An auditory illusion of a tone that seems to continuously ascend or descend in pitch, yet never gets higher or lower. Like an audio barber pole.
When two slightly different frequencies play in each ear, your brain perceives a third "phantom" beat. Used for relaxation and focus. 🎧 Headphones required!
