A dog whistle is a type of whistle used in the training of dogs and cats.
We have a dog here, his name is 'Happy'. We tried some "Dog Whistle" applications and we didn't notice any change of behavior. We decided to play with some low-high frequency sounds and we ended up realizing that other apps were not playing the sounds right. We decided to make this application for our dog, it worked so well that we decided to make a nice interface and upload it into the store.
You will love our app, you will even see a very cool animation inside!
Normally, a dog whistle is within the range of 16000 Hz to 40000 Hz with only the frequencies below 20000 Hz audible to the human ear. Our whistle has adjustable sliders for active control of the frequency produced.
These kind of whistles are also used to determine the hearing range of people or for physics demonstrations.
