- A tone generator produces a single clean sound at a user-selected frequency, from 1 to 20,000 Hz, and operates entirely within a browser without downloads.
- Common uses include testing speakers and headphones, checking hearing, tuning instruments, easing tinnitus, teaching sound concepts, and setting up audio gear.
- The tool offers four sound shapes (sine, square, sawtooth, triangle), left/right channel control, real-time adjustment, and shareable links that preserve settings across devices.
- Choosing the right frequency depends on the target: 20-60 Hz for subwoofers (testing rattles), 200-2 kHz for voice/matching speakers, and above 10 kHz for tweeters and hearing checks; 440 Hz is standard for tuning instruments.
