The other day a friend of mine called on his iPhone 4, and it took me two minutes before I figured out whom I was talking to. (The fact that I was talking on a samsung phone probably have something to do with that...)
Having two microphones makes a huge difference, you don't even need to be too clever with the processing. There is not much you can do with a single mic, you have absolutely no spatial information, so you can pretty much only suppress stationary background noise.
Impressive test. I wonder with the recent iFixit article revealing it's the same Audience processors used in various handsets including the Nexus One whether they would fair just as well or whether the iPhone 4 has a leg up due to other choice components in addition tot the Audience processor.
@rgisassi: Excellent question. You cannot turn off the built in noise cancellation for the handset microphones. If you are using a bluetooth headset, it will not have any noise cancellation. I have not researched it, but the built in speakerphone may not use noise cancellation either.
@rgisassi@rgisassi The iphone 4 has more than one mic. One is there to talk into, and the other is there to suppress noise. The one you talk into is at the bottom of the phone, and the other one that suppresses the noise is by the headphone jack (it looks like a tiny hole, but it's a mic that can be used for speakerphone and VOIP, as well as noise suppression). It stands to reason that if you cover this mic up, it would have less background noise to suppress.
Hi, which software did you use to generate the synthetic female voice? It sounds really nice, thank you!

You got that backwards. Apple had an agreement in place with Audience long before Google became interested.

@prosserd Then you just copied me because you used the internet.

Can you turn the voice cancellation on and off? Sometimes, I want the other caller to hear my background.

@almostzero Bluetooth headsets have their own noise suppression.

@rgisassi just cover the secondary mic (the little hole near the headphone jack) with you finger. In theory this should work.
