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. The tone is a pure
sinusoid. Don't be surprised if you can't hear tones over 10,000 Hz. (You can
see the high frequencies if you use the Spectrogram or SpectrumAnalyzer apps.)

When the tone is ON, the thumbwheels are grayed out and the user cannot change
the frequency. The thumbwheels can be freely changed when the tone is OFF.

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.

This program was developed on an Evo 4G. The Evo 4G was able to play the high
pitched sounds. While testing the phone at night, the sound woke our dog from
a deep sleep and she suddenly stood at attention, even though the sound was
completely inaudible to me. So this program can be used as a dog whistle.

The program uses the new Google licensing standard. In theory this means the
program can be copied to an SD card, freeing up internal memory in the
Android, although I haven’t tried it.

I am very interested in receiving feedback or any recommendations for
improvements to this application. I’m a new business and will be grateful for
the feedback. Please contact me at
[support@andwaves.com](mailto:support@andwaves.com) with any questions or
recommendations that you may have.
