Description

From the listing uploaded by “orcinusadamantos”.

is the App that allows you to detect ultrasound (ultrasonic) acoustic signals above the user-defined frequency (above 18 KHz by default). 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. The upper working frequency is depend on the audio specification of the current Android device and can be reached up to 150 KHz if the external ultrasound microphone or sensor is used. Nevertheless, the internal microphone also can be used to determine the ultrasound signal but sensitivity and the upper frequency will be worse depending on the quality of the internal microphone. Moreover, the App is using an oversampling feature. So, you can see for example 25 KHz ultrasound even if your device digitizes only 22 KHz audio (44 KHz sample rate). If you have any problems or any suggestions to improve this application, please feel free to contact Thanks!
