音ごこち - 睡眠・集中・リラックスのための環境音ミキサー

The sound of rain, the murmur of a cafe, the gentle sound of waves—"Otogokochi" is an ambient sound mixing app that creates your own soothing sound space to support your daily sleep, concentration, and relaxation.

White noise and natural ambient sounds are said to have the effect of relaxing the brain and masking (canceling out) unwanted noise. This app guides you to the ultimate "Otogokochi" by allowing you to freely combine high-quality, soothing sounds.

Completely free, and supports background and offline playback. Ideal for daily sleep induction, or as background music for studying or working.

✨ Main Features and Characteristics of "Otogokochi"

1. Carefully Selected High-Quality Ambient Sounds and Infinite Mixes: Includes a collection of natural and everyday sounds such as "rain," "waves," "campfire," "cafe," "birdsong," "wind," "thunder," "insect sounds," and "brook." You can play a single sound, or select multiple sounds you find pleasant and finely adjust their volume using sliders (mixing). The combinations and volume balances are endless, such as "rain x cafe" or "waves x campfire."

2. Ready-to-Use Default Presets: For those who don't know what to choose, we've prepared presets with optimal balances (rainy cafe, beach, forest bathing, concentration mode, etc.). You can instantly play the best environment with a single tap from the home screen.

3. Favorite Mix Saving Function: Your best mix settings, created by finely adjusting the volume yourself, can be saved as original presets. You can recall your own unique "Otogokochi" anytime.


4. Fade-out Sleep Timer that Won't Disturb Your Sleep: Features a timer function ideal for before bedtime (minimum 1 minute, freely adjustable). At the set time, the sound slowly and naturally fades out to stop, preventing you from waking up. There's no need to worry about battery drain, allowing you to fall asleep peacefully.
