टोन जनरेटर

उपयोग कैसे करें

1. Make sure the volume is low, then press Play (the default volume is deliberately low).
2. Change the frequency (20–20,000 Hz) with the slider or the numeric field; it updates live while playing.
3. Switch waveforms (sine, square, triangle, sawtooth) to compare timbres.

टिप्पणियाँ

Tones are synthesized on your device with a Web Audio oscillator. What you can actually hear depends on your speakers or headphones — laptop speakers often reproduce almost nothing below 100 Hz or above 16 kHz. Loud sounds, especially high frequencies and square/sawtooth waves, can damage hearing, so always start quietly.

अक्सर पूछे जाने वाले प्रश्न

I cannot hear 20,000 Hz — is something broken?

Usually nothing is broken. The upper limit of hearing decreases with age, and playback hardware has its own limits. Avoid leaving an inaudible high tone playing at high volume.

What are the 440 Hz and 1000 Hz buttons for?

440 Hz is the standard tuning reference (A4) and 1000 Hz is a common reference frequency in audio testing. The buttons jump straight to them.
