Description

From the listing uploaded by “orcinusadamantos”.

is the App that allows you to detect infrasound (infrasonic) acoustic signals below the user-defined frequency (up to 30 Hz by default). Infrasound propagates hundreds of miles and can penetrate walls, mountains and other obstacles without loss. This detector can be useful in following cases: Result of detection can be shown on the screen in the foreground mode and also be presented in the notification form and (or) by sound (vibration) in the background mode when the screen of the Android device is turned off. All events can be recorded in the log for later analysis. The lower working frequency is depend on the audio specification of the current Android device and can be reached as low as 4 Hz. For better result, the high quality Android device with internal microphone should be used to determine the infrasound signal, but sensitivity on the lowest frequencies will be worse anyway. Also, you can use a special external infrasound microphone connected to the audio jack (microphone input of the ear plug connector). The idea of the App is based on the fact that any analog system (microphone and amplifier of your Android device in this case) does NOT have ideal characteristics and infrasound signals can be infiltrate through it down to 4 Hz. If you have any problems or any suggestions to improve this application, please feel free to contact Thanks!
