Frequently Asked Questions
Everything you need to know about processing files securely in your browser
What waveforms can this tone generator produce?
This tool can generate Sine (pure tones), Square (buzzing/retro chiptune), Sawtooth (harsh/brass-like), and Triangle (soft/mellow) waves, as well as White Noise (constant spectral density) and Pink Noise (deeper acoustic static).
How do I play a specific sound frequency?
Select the waveform type, enter the frequency in Hertz (Hz) in the input field or use the frequency slider, set the volume, and click Play Tone.
What is a frequency sweep (chirp)?
A frequency sweep transitions a tone from a starting frequency to an ending frequency over a set duration (e.g., sweeping from 200Hz to 1000Hz in 3 seconds). It is commonly used to test speaker responses.
Can I download the generated audio?
Yes, you can configure the duration of your tone, sweep, or noise, and click Download WAV to export a high-fidelity 16-bit PCM WAV file directly to your device.
Is this tone generator safe for my hearing and speakers?
Yes, but you should always start with a low volume (below 20%) and gradually increase it. Extreme high-frequency or low-frequency tones at high volumes can damage hearing or blow speaker drivers.
