Show HN: Tone Generator
A web-based tone generator tool allows users to play specific frequencies between 1 Hz and 20,000 Hz directly in their browser. The tool supports various sound shapes and is designed for testing audio equipment and speaker performance.
Why it matters
This tool provides a free, accessible utility for audio engineers, hobbyists, and consumers to troubleshoot sound systems without needing specialized hardware.
A tone generator plays one clean sound at the pitch you choose. You type a number in hertz (Hz) and the tool plays that exact tone. It all happens inside your browser, so the sound starts the moment you press play. Nothing to download, nothing to set up.
You can play a low 40 Hz tone that you feel more than hear, a middle tone like 440 Hz, or a 15,000 Hz tone near the top of human hearing. Some people call this an hz generator ; others call it a frequency generator . Same thing.
Any pitch Play anything from 1 Hz to 20,000 Hz. Type a number, or step it one hertz at a time.
Four sound shapes Sine is the cleanest tone. Square, sawtooth and triangle sound fuller and sharper.
