This app is a simple sound generator designed to produce high-frequency tones at your desired frequency range.
Unlike regular music, high-frequency sound (above 17kHz) approaches the upper limits of human hearing and can be used in a variety of contexts such as testing, experiments, or attention signals.

Key Features:

Frequency selection (e.g., 17kHz~20kHz)

Adjustable via an intuitive slider

Easy start/stop sound control

Usage Examples:

Sound sensitivity testing

Experimental sound generation

Alert-style tones in quiet environments

⚠️ Please use high-frequency sound responsibly. Prolonged or high-volume exposure may be uncomfortable for some users.

This app is a basic tool and does not claim any medical or scientifically proven benefits. The audible experience may vary depending on your environment and device.

With a clean and minimal interface, this app is easy to use and suitable for experimental or personal purposes requiring high-frequency sound output.
