Sound Application 'Triangles' Now Available on Steam and App Store

DETUNE Ltd. (President and CEO: Nobuyoshi Sano) announced the release of its new sound application, "Triangles," now available on Steam and the App Store.

Unlike conventional Digital Audio Workstations (DAWs) that strictly bind sound to a single timeline, "Triangles" offers a spatial approach to audio placement. The app generates sound whenever a bouncing ball strikes a user-placed triangle, allowing for the creation of continuous, generative geometric soundscapes.

## Product Overview

"Triangles" is a creative sound application where users generate music by freely arranging triangles on a field for balls to bounce against. By adjusting the placement of triangles, notes, and octaves, users can design their own unique soundscapes.

The application requires no prior knowledge of music production or instrument playing skills, offering an intuitive creative experience suitable for all ages where shapes and movements translate directly into music.

Notably, this is the first application developed entirely by a single individual—Nobuyoshi Sano (sanodg), leveraging his career as a game music composer and software development know-how from products like KORG DS-10 and KORG Gadget, by collaborating with the AI assistant "Claude" (Anthropic) from development through release.

## Features

- Free placement of triangles on a broad virtual field.
- Intuitive mechanism where sounds are triggered when balls hit triangles.
- Realistic stereo panning (sounds positioned on the right side of the screen are heard from the right).
- Acoustic design that allows perception of off-screen sounds, with reverb deepening based on distance.
- Spatial effects where zooming out deepens the reverb and applies audio filters.
- Different sound profiles generated by multiple ball types.
- Import capability for up to eight original WAV files.
- Scale and key selection functions that ensure musical harmony even with intuitive operations.
- One-click randomization for notes, triangles, and balls.
- Copy-and-paste functionality to construct music as if drawing a picture.
- Customizable colors for triangles, balls, and the background.
- Support for saving and loading projects.
