3D Audio
Add headphone space with short inter-channel delays and adjustable stereo width. A stereo spatial effect uses mid/side width and a short cross-channel delay. It is not an object-based surround or head-tracking renderer.

Build headphone depth
The 3D treatment combines a mid/side width matrix with a quiet delayed crossfeed. It changes spatial cues in a two-channel recording rather than generating discrete ceiling or rear speakers.
Compare a centered voice
Listen to a familiar vocal passage while changing width. The singer should remain intelligible as the surrounding instruments spread; reduce the setting if the center becomes hollow.
Keep spatial delay short
A few milliseconds can suggest distance. Longer values approach an audible duplicate and can blur percussion, so audition both headphones and ordinary speakers.
Verify mono compatibility
Delayed components may interfere when speakers or a phone sum both channels. Export the spatial version, check it with Stereo to Mono and keep a less-wide version if important instruments disappear.
