Commonly used for: • Make you own experiments with sound generation. • Testing own hearing. Human ear is capable of hearing frequencies between 20Hz to 20000Hz. • Use this app as an instrument for playing or producing music. • Tune your musical instruments with musical notes presets. • Test speakers for high end (treble) and low end (bass) tones. • Discover how your audio handles sweeps of frequencies which range from ultrasound to infrasound. • Relax with binaural beats which play different frequencies in each ear. • Find a way to mask your tinnitus frequency. • Or have fun generating random sound effects, different frequencies and exploring all tone generation tools in this app. • Relax with white noise, brown noise, blue noise, violet noise, grey noise or pink noise playing in the background. Notes: • This app supports decimal values as input for frequencies when generating a tone. • This app makes an animated sound wave which tries to visualize a current frequency. • There are several waveforms available: sine, square, triangle and sawtooth. • Clean UI makes navigation simple through the navigation bar or pages where there are more frequency sound generating tools available. • Customize how the app behaves through settings menu where you can change themes, enable octave buttons, decimal points and more. • Phone speakers are not high-quality audio sources and may vary in quality. Sometimes a "parasite" noise can be generated by those speakers in very low or high frequencies which don't define the frequency. • Turn the volume down when creating high frequencies to not cause any discomfort when experimenting with the app. Privacy policy: https://www.frequencysoundgenerator.com/privacy Terms of use: https://www.frequencysoundgenerator.com/terms
