About this tool
Tone Generator is a free online tool. Generate sine, square, triangle, sawtooth tones and white noise with adjustable frequency.
Select the waveform type (sine wave, square wave, triangular wave, sawtooth wave), set the frequency (20Hz-20kHz), amplitude, duration, and click Play to generate an audio signal. It can generate single tone, double tone, sweep signal, white noise, pink noise, etc.
Audio generation uses OscillatorNode of the Web Audio API to calculate the value of each sampling point through mathematical formulas. Sine waves are the purest tones, and square waves and sawtooth waves contain rich harmonics. The sweep 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 burning, 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 are used to mask environmental noise, aid sleeping, or for acoustic measurements.
Audio signal generator generates audio signals of various frequencies and waveforms, including sine wave, square wave, triangular wave, and sawtooth wave, for testing and calibration.
