About Tone Generator
A client-side audio oscillator tool utilizing the Web Audio API to construct mathematically pure waveforms instantly. Whether you want to test the low-end capabilities of a subwoofer or find out what "mosquito sound" frequencies you can still hear, this tool covers it natively.
How to
Set Frequency
Dial in exactly the frequency in Hertz using the slider or direct numerical input.
Configure Audio
Select your preferred oscillator waveform. Keep the volume relatively low to avoid hardware damage.
Execute
Press PLAY. You can dynamically adjust the frequency slider while the note is playing seamlessly without clicks.
Glossary
- Frequency (Hertz)
- The number of complete audio waves hitting your ear per second. Higher values mean higher pitch.
- Hearing Limits
- Average human hearing spans from 20Hz (ultra low bass) to 20,000Hz (piercing high pitch).
- Mosquito Tone
- A sound played at ultra-high frequencies (above 15kHz) which older individuals frequently lose the ability to detect.
FAQ
- Q.I cannot hear anything.
- Ensure your hardware isn't muted. Also note that standard laptop speakers often fail to emit frequencies below 80Hz solidly.
- Q.Is it dangerous?
- Potentially. Synthesized sine waves contain massive energy. Start at 10% volume, especially when using headphones.
