An online tone generator lets you create precise audio tones directly in your browser. Whether you are testing speakers, learning audio basics, practicing music, or debugging sound systems, this tool helps you generate controlled frequencies without installing any software.
An Online tone generator is a browser-based audio tool that produces sound waves at specific frequencies. You choose a frequency value, select a waveform, and the tool generates a continuous tone in real time.
Traditional sound generators are physical devices or desktop software. Our frequency generator performs the same core function but runs entirely inside your web browser, without cables, drivers, or installations.
Our HZ generator online creates sound in real time using your browser’s audio engine. When you click the Generate Tone button, the selected frequency and waveform play immediately.
Everything runs directly on the page. You do not need to install plugins, apps, or extensions. This makes the tool fast, lightweight, and accessible from anywhere.
The tool works on most modern browsers across desktops, laptops, tablets, and smartphones that support basic web audio functionality.
frequency describes how fast a sound wave vibrates and is measured in Hertz (Hz), meaning cycles per second. A 440 Hz tone vibrates 440 times every second.
Lower frequencies produce lower-pitched sounds, while higher frequencies produce higher-pitched sounds. Adjusting frequency lets you hear this difference instantly.
A sine wave generator produces the smoothest and purest sound. It contains a single frequency with no added harmonics.
Square waves change sharply, triangle waves rise and fall evenly, and sawtooth waves ramp upward with a sudden reset. Each sounds different, even at the same frequency.
Enter a precise frequency in Hz or adjust a slider to fine-tune pitch.
Choose between sine, square, triangle, and sawtooth waveforms depending on your testing needs.
Start playback instantly and stop or reset the tone at any time for safe audio control.
Identify distortion, rattling, or frequency response issues in speakers and headphones.
Practice pitch matching, tuning, and interval recognition using consistent tones.
Verify audio output, volume behavior, and frequency handling in applications.
