Noise Cancellation

☆ Check out my other free app “Sonic Messenger”. A messaging app that uses ultrasonic sound to communicate.

This app does audio amplification of low audible signal and noise cancellation in real-time. The app allows the operator to design custom ideal filters such as Lowpass, Highpass, Bandpass and Bandstop filter by drawing on the touch screen. You must plugged a headset( or headphone) into the device headset jack. This is a requirement in order for the app to work. The app also amplify your surrounding environment and act as a hearing aid as well.

Three Noise Filter Modes:

1) Auto:

- Removed the frequency with the highest decibel level.

- Preset the voice range from 300 hz to 3.5kHz

* Will add more preset range in future release.

2) Standard

- Remove frequency range using bandpass filter.

3) Advance

-Can remove certain frequencies using the drawing method on the graph.

* Note: when this mode is selected, draw the frequency using the touch screen method.
