Noise Canceller

Noise Canceller


1.0.2: Fix more FC bugs.
As the name suggest, this app will try to lower the environment noise by generating a phase-inverted wave of the noise. Due to a delay of sampling and playing(no realtime sound api in android), user will need to change the phase and amplitude manually to get the best effect.

Great idea but to slow. If the galexy s5 can't work it I don't know what can .

I was hoping the bad reviews were wrong I wanted it to work but it does not. I hoped that people thought it didn't work cause it didn't cancel out sudden noises like voices or keyboards but it doesn't work for me to cancel out the constant noise of fans in my server room. It actually makes the problem worse. I tried slowly moving through different amplitudes and phase offsets but no luck. Its a shame but I expect it is partially the fault of the microphone. It isn't really designed to pick up background noise with enough clarity to do the trick.

Good idea... But makes worse This app was designed after the active noise cancellation concept, but it is delayed by over a second. This causes the app to repete the noise again.

Too much process lag. Just over 1 second delay can be heard. So it'll cancel out 1hz and below.... Lol

HTC One Couldn't get it to work on my phone. However, the HTC One has a built-in noise canceling mic for in call use. On the back of the handset at the top right. The HTC One, LG G2, Galaxy S4 & S5 all use the Qualcomm Fluence technology specifically designed for this purpose. This app can really work and work well, it has the potential. Sadly, only with the right phone I think. To have a mobile noise canceling device would be awesome :). This can really work Haowen, and I will happily pay for it when it does :)
