Download Frequency Sound Generator and create precise tones, sound frequencies and audio sweeps whenever you need them.

Note: Phone speakers and audio hardware have different frequency limits. At extremely low or high settings, you may hear distortion, static or other audio artifacts instead of the selected frequency. These sounds are produced by the device’s audio system and do not necessarily represent the generated tone. For more accurate playback, use good-quality headphones or external speakers at a safe volume.
