MultiTone Generator

I use it to silence the neighbor’s dogs when they decide to bark too much. The program runs on my old iPod Touch that sits on our kitchen counter. The iPod is connected via bluetooth to an inexpensive stereo amplifier in our back yard, with each of the amplifier’s channels connected to a tweeter — and each tweeter is pointed at the dogs. When the dogs bark, I activate a high frequency audio sweep (just above the neighbor’s audible range) and the dogs quickly shut up and go inside! Thanks for this very useful application!!!

Totally satisfied again with the app, and the customer service. The developer speedily responded within 48 hours, and remedied the issue within a few days of the email. I no longer would like a refund, and the app is once again useful to me. Its back to working when my screen is locked or unlocked. Please disregard my previous review. This is a 5 star app. Thanks!

I have recently acquired tinnitus. It seems directly related to the use of Kratom which has killed all pain and panic disorder since an accident in 1993. Kratom also knocked down the meds I’ve been on for ten years within five months. The tone is a C9 or C10 if a piano could reproduce it. C9. I matched it to either C9 or C10 on the using the app. I’m getting close to the middle of C9 by going up in thousandths. I am getting close. The app is perfect. The features cover all my uses. I tried the three top apps. Even the lite version is feature laden. When I finally determine the exact C9 sine wave's frequency. I will know the exact negative wave that will cancel it out. The app already makes it go away for a few minutes. Only use it with care for this purpose. A little at a time. Short sessions. If you could invent an app that plays negative sine waves, you would have the cure for tinnitus. The negative wave will make tinnitus disappear. They cancel each other out. Then, a small ear piece that fits inside the ear, which would be cheap to make, millions would beat a path to your door. Thank you so very much.
