―― About the App ――
ARSound3D is an innovative spatial media player that lets you freely place
your own music, videos, and photos into AR space or virtual space,
and play them back with a strong sense of presence and immersion,
as if they truly exist there.
With a uniquely tuned audio playback engine, ARSound3D supports
spatial audio and immersive sound.
Audio and visuals placed in space feel naturally blended with reality,
offering an experience beyond simple playback
— a world of “touchable” sound and visuals.
Use photos from your library and your favorite music or video files
to design your own personal sound-and-visual space within everyday scenes.
It also works perfectly as background music for work or daily activities,
creating the feeling that performers are right there with you.
―― Main Features ――
• High-quality audio playback with a uniquely tuned engine
(supports up to 48kHz / 32-bit)
• Dynamic spatial playback for mono audio (1Ch_Act mode)
Sound moves dynamically through space in response to camera motion,
creating a deeply immersive experience as if you are inside the music.
*Audio is played back in mono.
• Immersive spatial sound with stereo separation and fixed placement
(2Ch_Fix mode)
Experience a live-stage-like presence, as if music is unfolding
right in front of you.
Stereo sound is fixed in space, surrounding you with depth and width.
*Sound positions are fixed and do not move dynamically.
• Background playback support
(with improved controls and full Apple Watch support)
Music continues playing even when the app is closed.
Enjoy immersive sound while commuting, jogging, cooking, working,
or studying.
Playback can be intuitively controlled from iPhone,
the lock screen, and Apple Watch.
*Controls remain simple while ensuring smooth operation.
• Wired headphones recommended & Bluetooth supported
For the best spatial depth and realism, wired headphones are recommended.
Bluetooth headphones are also supported, with optimized audio routing
for high-quality playback.
