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.

Not working Someone should redo this concept in a way that actually works.

Great concept, but.... The delay in the phone is enough that it can be clearly distinguished between the source and the headphone output. In my case over 1 second of delay. There is no way, even with 359 degrees of phase adjustment that this app can cancel sound. It is not necessarily the app but the delay produced in the phones circuitry. This app will only work on a phone with no delay.

Nice try Latency is too great to work. Shame. Not to mention the awful tinnitus creating noise that suddenly comes out of nowhere... NOPE
