note

The Hass effect is a psychoacoustic effect in digital audio where duplicating an audio signal, panning each to opposite directions, and then overlapping them with one signal having a delay <40 ms produces the perception of a single “wide” audio

It is a common illusion used in music production for “stereo widening”

• Seems to be referring to the precedence effect?

I wonder if there is any perceptual learning stuff involved? #question
