Free Tone Generator — Generate Sine, Square & Sawtooth Waves

Generate pure tones in sine, square, sawtooth, or triangle waveforms from 1 Hz to 20,000 Hz. Ideal for audio testing and instrument tuning.

How It Works

Select a waveform, set the frequency, adjust the volume, and click Play. Each waveform has a distinct harmonic profile: sine is pure, square is rich in odd harmonics.

Tips for Best Results

  1. 1. Sine waves produce the purest tone — only one frequency component.
  2. 2. Square waves sound bright and buzzy — great for chiptune music.
  3. 3. Use the volume control to avoid hearing damage at high frequencies.
  4. 4. Preset musical notes (A440, C523) are available for instrument tuning.

Completely client-side: all processing runs in your browser without any data uploads.
