Audible Frequency Tester
Frequency: 440 Hz

Frequency Tester Introduction
This tester allows you to listen to various frequencies. The volume is set to -16 LUFS, but because these are test frequencies, the sound may be unpleasant to hear. Please be cautious when using earphones.
How to use
On mobile phones and tablets, it should work with touch controls, but on a computer, you can adjust the frequency and play/pause using the arrow keys and the spacebar.
Caution!
Fade-in and fade-out settings have been added to prevent sudden surprises. However, as mentioned earlier, since this involves frequencies, the sound may be unpleasant to hear. Please be mindful of the volume and use of earphones!
