Our tone generator creates audio waveforms at specific frequencies using the Web Audio API's OscillatorNode. You can choose from sine (pure tone), square (rich harmonics), sawtooth (bright), and triangle (soft) waveforms.
Tone generators are essential tools for audio engineers testing speakers, musicians tuning instruments, sound designers creating effects, and researchers conducting hearing tests. The frequency range covers 20Hz to 20kHz (the full human hearing range).
It produces audio signals at specific frequencies and waveforms for testing and tuning.
