About This Tool
What is Tone Generator?
A tool for generating sound at a specified frequency and waveform. Useful for speaker testing, instrument tuning, hearing checks, and sound experiments. Supports four waveforms: sine, square, sawtooth, and triangle.
How to Use
- Enter the desired frequency (Hz) or select from presets.
- Choose a waveform (sine, square, etc.).
- Adjust the volume.
- Click 'Play' to generate the sound.
Key Features
- Free frequency setting
- Sine, square, sawtooth, and triangle waveforms
- Volume control
- Preset frequency options
Tips
- A4 (the note A) at 440Hz is the standard tuning reference.
- Sine waves produce the purest tone; square waves sound more electronic.
- Prolonged listening at high volume can damage hearing — use caution.

Frequently Asked Questions
What is the difference between sine, square, sawtooth, and triangle waves?▼
Sine waves produce a pure, smooth tone with no harmonics — ideal for tuning and hearing tests. Square waves have a buzzy, electronic sound with odd harmonics. Sawtooth waves contain all harmonics and sound bright and harsh. Triangle waves are softer than square waves, with a hollow, mellow tone.
Can I use this to tune a musical instrument?▼
Yes. Set the frequency to your target note (e.g., 440Hz for A4) and play a sine wave. Compare the generated tone with your instrument's note by ear. For more precise tuning, use a dedicated tuner tool that detects pitch from your microphone.
What frequency range can humans hear?▼
Most humans can hear frequencies between 20Hz and 20,000Hz (20kHz). Sensitivity is highest around 2,000-5,000Hz. Hearing range naturally decreases with age, especially at higher frequencies above 8,000Hz.
