Otoyoi — Spatial Sound Layers

Music, voice and ASMR — all playing at once. Otoyoi plays as many audio files as you like, together. A whisper at your ear, rain in the distance — you decide where every sound sits, and move it with a fingertip. ■ Ways to listen - Layer rain or a campfire under your favorite ASMR and voice works, at just the balance you like - Turn on "Play alongside other apps" and keep listening while you watch videos or play games - Build your own sleep soundscape from streams, birds and wind - Blend a personal ambient mix for work and focus - Practice an instrument or a language: change the speed and compare a reference with your own recording ■ Move sounds with your finger Drag a sound on the pad to move it left, right, up or down; pinch to bring it closer or push it away. Put on headphones, and each sound plays from right where you placed it. ■ Fine-tune every track - Volume (up to 200%) and speed (0.25–2x, pitch-preserving) - 5-band equalizer - Repeat, and Swap L/R (play a stereo track with its left and right channels exchanged) - Queue: combine multiple audio and video files into one track and play them in order (great for split audio works) - Seek anywhere, and play or pause each track on its own ■ True-to-source stereo Binaural ASMR and voice works lose their magic when they are processed. Otoyoi's default mode preserves the original stereo image and only adjusts balance and distance. Want full 3D placement instead? Switch any track to spatial mode. ■ Videos, audio only Audio from video files works just like any other track. Hide the picture with a single tap and keep just the sound playing. ■ Built for bedtime - Sleep timer that ends in a slow fade-out - Auto-pause when your headphones disconnect - Lock Screen controls, plus 10-second back and 30-second forward skips - Resumes where you left off ■ And more - Head tracking with supported earphones - Export your mix as an m4a file and play it in any player - Save and switch pads (scenes); back up and restore everything - Four dark themes that belong to the night - iPhone & iPad (two-column layout on iPad) ■ First launch Otoyoi ships with "Camp Morning" — a demo of self-made ambient sounds (Babbling Brook, Songbirds, Campfire) already placed in space. Put on your headphones, press play, and try moving the sounds with your finger. ■ Good to know - Play only files you own or are licensed to use privately - No data collection. Your audio never leaves your device - Headphones recommended Music, voice, ASMR — a small, quiet tool for people who love sound.
