Tone Generator

How to Use the Tone Generator

1. Adjust the frequency slider or type a precise value in the number field.
2. Choose a waveform: Sine (pure tone), Square (buzzy), Sawtooth (bright), or Triangle (mellow).
3. Click Play to start the tone and Stop to silence it.
4. Use preset notes to jump to standard musical pitches (A4 = 440 Hz).
5. Click A440 Reference for the standard tuning reference tone.
6. The waveform display shows the shape of the audio signal in real time.

Waveform Types

Sine — the purest tone with no harmonics. Smooth, clean, and used as a tuning reference. This is the fundamental building block of all sound.

Square — contains only odd harmonics, creating a hollow, buzzy sound. Similar to a clarinet or vintage synthesizer. Rich and penetrating.

Sawtooth — contains all harmonics (both odd and even), making it the brightest waveform. Similar to a bowed string. Great for rich, full sounds.

Triangle — similar to a sine wave but with some odd harmonics. Softer than square, mellower than sawtooth. A gentle, flute-like quality.
