Otoyoi is an iOS player that plays multiple audio files at once and lets you place each one anywhere in space around you.
Any audio format iOS supports natively (m4a, mp3, wav, aac, etc.), plus audio extracted from video files. You can add files from anywhere accessible in the Files app (iCloud Drive, On My iPhone, etc.).
Songs from subscription services such as Apple Music are DRM-protected and cannot be played in this app. Please use only files you own or are licensed to use privately.
Spatial placement is best experienced with headphones or earphones — we strongly recommend them. Stereo sources have two modes: "true-to-source stereo" (preserves the original stereo image) and "spatial" (full 3D placement). You can switch per track in the track detail panel.
Yes. From Settings you can export all scenes and audio into a single backup file (.aar) and restore from it — useful when moving to a new device.
