Description

From the listing uploaded by “apps”.

Frequency Generator Sound player lets you generate a sine, square, sawtooth or triangle sound wave with a frequency between 1Hz and 22000Hz. It produces accurate tone while being simple and easy to use. This sound generating app can be used in multiple use cases: ● You can test your hearing. Human being is capable of hearing frequencies in average range of 20Hz-20000Hz. This range is getting smaller by the age. ● Testing your speakers for the high end (treble) and low end (bass) tones. ● Cleaning water from your smartphone speaker. Since sound is making small vibrations it can help shaking of unwanted water from your speakers. ● Having fun and making experiments with sounds. There is also an animated wave function which visually represents the sound for a given frequency. You can change waveform by clicking on a round button at the left side and get different sound. Adjust tone frequency using a slider, number pad or + and - buttons and press the play button. In the App Settings you can choose if you want frequency sound to continue playing in the background when you minimize the App and also if you want to show an animation of the sound wave.
