About this tool
Tone Generator is a free online tool. Generate sine, square, triangle, sawtooth tones and white noise with adjustable frequency.
Select the wave type (long wave, square wave, triangular wave, sawtooth wave), set the frequency (20 Hz-20 GHz), amplitude, duration, and click Play to generate an audio signal. It can produce single tones, double tones, swept frequency signals, white noise, pink noise, etc.
Audio generation uses Oscilatorode of the Web Audio API to calculate the value of each sample point through mathematical formulas. The peak is the purest tone, and the square and sawtooth waves contain rich harmony. The scanning signal gradually increases from low frequency to high frequency and is used to test the frequency response of the speaker.
Suitable for audio equipment testing, speaker firing, hearing testing, and acoustic experiments. You can generate tones at specific frequencies to check the frequency response curve of your headphones. White and pink noise is used to mask environmental noise, aid sleep, or make acoustic measurements.
The audio signal generator generates audio signals at various frequencies and forms, including long waves, square waves, triangular waves, and sawtooth waves, for testing and calibration.
