About Tone generator
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

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.
