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.
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 :)
Terrible A simple test on any phone would have made the author aware that this is ineffective and useless. Stop publishing garbage just because you can.
Great idea, I was hoping it'd work but it needs more development (either the app itself or additional Android functionality).
Definitely does not work Repeats noise back without any options to delay the playback to knock it out of phase - it just replays the noise on top of what you can already hear!
Good idea but doesn’t work Noise Canceller app: I would pay if the app works. It replays the conversation as an echo. It doesn't cancel. the background noise, as I hope for. The developer also mistakes phase shifting with delay adjustment. Adjusting the phase of the output does nothing to the delay. I hope he would let the app sample background noise, and allow delay, phase, and volume adjustment of thr output. I would like to use this to reduce driving noise in a car someday. Thanks.
