Sound Terrain app analytics for October 6

Sound Terrain turns a field of colored cells into a small instrument. Tap to switch notes on and off, brush across the surface to strum, or hold to capture up to eight seconds of sound and release it across the terrain. Explore dust, wind, clicks, drones, bells and plucks. Spread two fingers to reshape a short tape loop. Draw an L for an echo, or trace a circle to leave a repeating phrase. Double-tap to mute a sound type. Your samples return as scattered grains, reverse playback and vocoder-like textures. Use rec to record a performance, then save or share the audio. Tilt your iPhone to send particles through the field, or enable camera brightness control to change speed and pitch by covering and uncovering the lens. Choose a palette or let colors follow the time of day. English and Chinese interfaces are included. Sound synthesis and recording work offline. No account, advertising or subscription. Microphone, camera and motion controls are optional. Samples are temporary and cleared by reset or closing the app process; exported performances remain wherever you save them. Playback pauses in the background.
