Tone Generator5.2.1
Publisher Description
Generate pure sine wave tones at frequencies from 20hz to 22,000hz.

Tone Generator has many uses:
- Hearing Test: What is the lowest/highest frequency you can hear in each ear?
- Tuning Instruments: Does your top guitar string match Low E at 440 Hz?
- Science Experiments: What is the resonant frequency of your wine glass?
- Audio System Test: What frequencies does your subwoofer support?
Directions:
Adjust audio frequency by dragging the slider or tapping the plus/minus buttons. Adjust device volume using the on-screen volume slider. Toggle audio playback using the Play/Pause button.
