noise cancellation - Touch Pro2, Tilt 2 Windows Mobile General

in settings->phone one can turn the noise cancellation for phone calls on, off or set it to automatic. what does automatic mean?

"On" refers to constant effort on the phone for noise cancellation, provides the best quality/effect.
"Automatic" means that the phone will sample the noise level at the beginning of the call and then apply that as the level of noise cancellation for the entire call.
The "on" option provides better quality but will drain the battery faster as it requires more processing power. The second one will provide some noise cancellation but not as good, but on the other hand it will also be the best middle point between noise cancellation and battery usage.
"Off" obviously just means off and won't require any extra effort from the processor and the battery.

this means that if i start a call in my house and go outside (there is a noisy street in front of my house) the cancellation does not get activated, right?

Where did you get the information on energy consumption from? i checked the manual, unfortunately it did not contain any valuable information about the noise cancellation.

it does not sound plausible to me that there is a relation between the aggressiveness of the noise cancellation and the requirement for processing power.

From page 53 and 54 of the manual:
To turn noise reduction on or off
When you are using the earpiece and not the speakerphone during a call, you can
tap Menu > Noise Reduction On to reduce ambient noise if the other party cannot
hear your voice clearly. When noise reduction is not needed, tap Menu > Noise
Reduction Off to disable it and save battery power.
You can also turn noise reduction on or off in the Phone settings. Tap Start >
Settings > All Settings > Personal tab > Phone > Advanced tab and then select
one of the following settings in the Reduce noise in phone calls drop-down list:
Automatically. Analyzes ambient noise only at the beginning of a connected
call and applies a certain noise reduction setting based on the detected
noise. However, when you move to a noisier environment during the call,
your device will not further decrease noise based on your new location.
Always. Always reduces ambient noise during the entire course of your phone call.
Never. Turns off noise reduction.
Notes
• If you want to change the noise reduction setting to Automatically, make sure to do this before starting a call.
• Noise reduction is not used when you have a wired or Bluetooth headset connected.
And actually the relationship between noise cancellation and processing power is logical. When it is on "automatically" it analyzes, then sets a level of noise cancellation for the entire call. If it on "always" or "on" as it appears on your phone, then it is constantly analyzing the noise levels, not just at the beginning. It is processing the noise levels, thereby requiring more processing power
Hope this helps.

damn i somehow missed that paragraph, thank you!

No prob. Now go and enjoy your phone and play with it some more

Secondary microphone noise cancelling?

Hello, Im probably buying TP2 and one main features i want is that noice cancelling microphone.
Does it work while in normal calls or just in straight talk mode?
it works only during normal calls and not in handsfree mode.
That's wrong. It works automatically with the speakerphone function. For normal calls you can activate it. There are three settings for normal calls:
"On", "Automatic", and "Off". "On" has constant noise cancellation and will use more CPU and therefore I'm guessing will run down the battery faster. "Automatic" takes a sampling at the beginning of the call and based on that uses one set of noise cancellation for the entire call, which means if you change from a quiet to a noisy environment mid-call it won't help you much. "Off" I'm guessing is self evident. you have to choose the setting before the call is made/answered for it to be of any effect.
This is all in the manual.
thank you much, this helped me lots.
noise cancelling is best feature for some time in phones.

For 6.1:
Start-settings-personal (tab)-phone
Then you'll need to scroll to the right, across the bottom tabs, until you get to the one that says "advanced". The drop-down list with these options will be at the bottom of the options on that tab.

[Q] noise cancellation setting

Where can I find setting for noise cancellation?
I know that defy has a second mic (near camera has a hole) but I cant find any setting for that and i dont know if it works.
There in not exactly an noise cancellation setting but an voice quality setting.
If you look in settings, call settings, voice quality , then you can select from standard, balanced, bright or extra bright.

thought that was bass control or something..
So will set it bright and see how this behave..
TNX!
The only bass adjustment i can see is for headphones and the external speaker in settings, sound & display, media audio effects , but it`s not for the earphone.

In Cyanogenmod 7 these settings are not visible, does anybody know if that means that CM7 doesn't support noise cancellation?

Thats a good question sir. Can anyone else report a decrease in voice quality on the defy? Does noise cancelling work for normal voice recording too?
It ends up distorted on normal recordings.. Instead you can record in stereo

"Samsung" Galaxy Nexus noise cancelling phone

Im suspect there is no noise cancelling on this phone which Samsung built it.
How to enable noise cancelling when in call??? Samsung dont want to answer
and also why this phone keep switch it display on automatically when in idle (switch off the display)
Yes it did. The 2nd mic is in the back under small notch of back cover. That's the noise cancelling microphone.
If you don't want the screen to turn off there is a setting for that.
Unfortunately the second mic does not work for noise cancellation during calls. Only for video recording. The hardware is not present to use it during phone calls.

That seems rather silly. I was wondering if this was the reason groove ip behaves so differently than on my other phone but I guess not if it's not being used...

[Q] Noise Reduction

Hey,
is there an app or setting when your talking on the phone that the outside noise will be reduced just like on that iphone 5 commerical
Call Settings->Additional Settings->Noise Reduction.

Anyway to remove noise suppression in video recordings?

There's noticable noise suppression in video recordings which really affect the audio quality. As much as I like it on phone calls, I don't always record voices when shooting video. The noise suppression really destroys the sound of the environment. Anyone know a way to disable it?

Only way which I think is shooting in manual mode and disable wind filter, and optionally use HiFi audio recording which will enable recording sound track in lpcm.
But I very much doubt that tiny mics of G7 are capable to correctly picking ambient audio of 10-20 dB volume levels. They're too tiny, you should rely on external USB microphone with much higher sensitivity
