Granula vs Sound Terrain

Granula is a granular synthesizer for the phone. It takes a sound from demo samples (like guitar, calimba, tongue drum, etc.) or thirty seconds you record on the spot and scatters it into hundreds of tiny overlapping grains. A slow, shifting texture comes back to your space: ambient pads, drones, atmospheres that keep evolving as long as you keep listening. Everything is played with your hands. The whole screen is a morph pad: move a finger across it and the sound moves with you, while a field of glyphs lights up under your touch and churns in time with what you hear. FOUR CHARACTERS • Reverse: short grains, played mostly backwards, with octave and fifth sparkles on top • Gater: a denser cloud chopped on a grid, from halves down to sixteenths • Chorus: long, slow, detuned grains with the read position drifting like a tide • Scatter: harmonic intervals thrown at random and sprayed wide FOUR KNOBS • Grain size, from 15 ms clicks to 1 second • Position: where in the sample the grains are lifted from • Density: from sparse drips to a solid wash • Dry/Wet: a six-second convolution reverb, plus the amount of reversed grains RECORD THE WORLD AROUND Hold the record button and capture up to thirty seconds of anything: your voice, a room, rain on a window, a string you plucked once. The take is granulated immediately and kept in your library under a name of its own. You can also import your own MP3 or WAV files. MADE FOR A PHONE • Keeps playing with the screen locked and in the background • Survives calls, headphone unplugs and output switches without losing your session • Any class-compliant USB or Bluetooth MIDI keyboard plays it - plug in and go, nothing to pair inside the app GRANULA PRO Every built-in sound is free and stays free. A free account also brings in one sound of your own - recorded or imported. Granula Pro lifts that limit: record and import as much as you like, and everything syncs to your account so a new phone picks up where the last one left off. No ads.

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.
