AudioGenerator has a very simple interface composed of 5 thumbwheels and an ON/OFF switch. Simply dial in the frequency in Hertz (cycles per second) and press the ON/OFF switch to start or stop the tone.
Many people cannot hear tones over 10,000 Hz. Such high frequency soundsfrom AudioGenerator, and any other sounds, can be visualized with the AndWaves Spectrogram app. This is shown in the Feature Graphic (along with sounds from our dishwasher).
When the tone is ON, the user may change the frequency.
Any frequency up to 22,050 Hertz is permissible. Volume is adjusted with the volume controls on the Android device.
The program is useful to musicians, engineers, dog trainers and people who just want to informally test their hearing.
We found that our dog was very responsive to some very high frequencies. While testing the phone at night, even though the high frequency sound was completely inaudible to us, the sound woke our dog from a deep sleep and she started barking. So perhaps program may be used as a dog whistle or a dog alert.
I appreciate receiving feedback or any recommendations for improvements to this application. Please contact me at firstname.lastname@example.org with any questions or recommendations that you may have.
