With its custom-tuned audio engine, ARSound3D supports spatial audio and 3D sound. Music and videos placed in space feel more immersive than ordinary playback. ARSound3D also supports text input and speech. You can enter text manually or scan text with the camera, then have it read aloud using Apple’s built-in TTS. Speech audio can be played from the front, right, left, or back, creating a spatial speech experience. Use your photos, music, videos, text, and code information to design your own space of sound, visuals, and words. Create your own immersive media space by placing sound, video, images, and speech around you. ARSound3D is useful not only for music playback, but also for background listening, study, creative recording, and social media content creation. You can capture your AR scenes with video recording or screenshots, making it easy to save and share your spatial media experience. ―― Main Features ―― • Custom-tuned high-quality audio playback • Dynamic spatial playback for mono audio sources Sound moves through space in response to camera movement. ※ Audio is played in mono. • Spatial stereo playback Left and right audio can be separated and placed in space.
