Noise cancellation is not a noise gate that clamps down and mutes the mic when someone isn't talking. It actively cancels background noise using phasing techniques, most importantly during conversations. When done well, it's a very nice feature.
Here is a video (top video in this link, Clayton Morris)
In this video, he says that the noise cancellation is being used for recording. The only thing that seems strange is how freaking steady he's holding he phone...looks like he has it attached to his body the way it moves with him perfectly.
But for the noise in that room, im blown away with the quality of his voice...seems to be cutting right through the bwckground noise.

Yep, great audio, but the video shows that in lower light situations the iphone is pretty much as bad as the competition. But then again I wasn't planning on replacing my cameras with a phone anyway.
It's been highly compressed for YouTube.
Compression doesn't cause the jittery way the background moves. Thats the camera, and it's evident in Apples own videos unfortunately.
What is this exactly?
Is it somekind of noisegate where the background ambient noise is blocked? `Cause if it is, that´s really annoying.
I was talking with my friend on the phone. I don´t know what phone he has, but I suspect his phone had this "feature". When he didn´t talk the line went always absolutely dead silent. I was wondering and asking him all the time "are you still there?". Totally frustrating!
The motion of the background itself? Surely that's an artifact of the camera vibrating during motion.
No. Watch the official Apple video. The background and often the foreground stop moving and then kinda leap to catch up. Its evident in this video as well. That's the optics and is a limitation of a phone camera. But again, who was buying the iphone in hopes that it would replace a real video camera?
You also believed that slow-mo required fewer frames per second so, no offense, but I don't put a lot of trust in your technical expertise.
I'm telling you that it's your computer that apparently can't play the files back smoothly...because it's perfect on my end, as well as the clip of the outdoor field we got yesterday..
Cool,bury your head in the sand. Not my problem.
Are you kidding me? You know the other person is done when they say goodbye and hang up.
What you are describing usually happens on CDMA networks, such as Verizon and Sprint. They usually do this over the network end rather than on the phone end, but the end result is the same. And I agree, its very annoying. GSM does not have any kind of built in noise reduction/cancellation features.
You have zero clue what you're talking about. On some phones with noise cancellation you dont hear the other person talking, thus creating the issue of talking over one another. So please, if you cant comprehend the issue, just shut it.
Ummmm yeah we do. Watch the keynote and steve will tell you exactly that noise cancellation is on the new 4 and that the hole by the hp jack is that speaker.
