Generate various periodic signals with different waveforms with adjustable frequency and amplitude. These are used to test electronic circuits such as amplifiers and filters. Also suitable for musicians to tune their instruments. As soon as a note sounds, the integrated tuner recognizes the pitch and displays the note name and deviation. For any instrument that produces an even tone. A metronome also helps you to practise. Drive insects away or compare your hearing ability with your friends and relatives and share your results! Or watch others straining their ears to find the sounds that cannot locate you. Party fun is guaranteed! optional features (Purchase): - free of Ads - manual frequency input - support app functionality for connected Bluetooth devices, e.g. speaker - different signals - white/pink noise - tuner for tuning instruments (real-time tone recognition C1-C8) with tuning whistle - metronome for a steady tempo - note/tone for frequency - Left/right channel, stereo - create a tone sequence for playing several different frequencies in particular time slot - loop for tone sequence - save and delete tone sequences - load saved tone sequences - send your tone sequence as an audio file (.caf format) - option to compress audio files Attention: If you want to share your results with others, first test your audible frequencies, then mark under the speakers your lowest audible tone and your highest audible tone (stored only temporarily). A small hint: the chart will show you what other frequencies of your age are still possible to reach.

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
