Tone Generator Pro

This app generates a constant tone (sine, square, triangle, or sawtooth wave) in the audible frequency range (20 Hz to 22 kHz), which may be adjusted in 1 Hz or 10 Hz increments. In addition, special sounds can be played to remove water from your speakers and to help you relax, meditate, and sleep better. Each of these main sections of our app is on a separate page, and more information about them will be displayed when you tap the About button. What else can this tone generator be used for?

- Tuning musical instruments and testing audio equipment
- To find out what is the highest frequency you can hear
- To interact with your dog and stop him from barking (note: longer exposure to the high-frequency range can damage the dog's hearing).

- To induce calm and relaxing thoughts during meditation and to meditate effectively and successfully.
