Is it possible to organize noise reduction on the phone when listening to music?

Question

Audio

Today I bought a player and I was simply shocked by the digital noise reduction system. When turned on, the player drowns out all the surrounding sounds, and the headphones on it are the most ordinary.
And the question immediately began to torment me, is it possible to provide such a digital noise reduction system programmatically on phones with android on board?

Answer 1

What kind of player is it?

Answer 2

Have you looked at active noise canceling headphones? Or does it need to be on the phone?

Answer 3

It seems that the LG P970 Optimus Black has such a thing, there is even a second microphone for this. Therefore, you can programmatically file ...

Answer 4

As I understand it, the player creates “white noise”, which is generally not useful for hearing, since pressure on the eardrums is still created, simply due to the fact that the waves of sound from the outside and the sound of the squelch are in antiphase, we do not we hear. So better headphones with passive noise reduction, and do not think that there are only huge a la studio ears. there are so-called "plugs" that are inserted into the ear a little deeper than the "droplets" and sit tight due to the rubber nozzle, it also ensures that the ear is closed from external noise.

Answer 5

For active noise cancellation, you need to have very low delays. On Android they are too high. Maybe it will work on the iPhone. But it is better if it is implemented at the iron level)
