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

Buy a Captivate.
I have a question for GN owners,
Is there an option in ICS to permanently disable the Noice Reduction feature during calls? Maybe it's in the Call/Sound settings? I'd appreciate if someone would look around for me.
good question, my experience with Samsung with call quality is not quite good (coming from an Galaxy S user).
I hope that Nexus has good noise reduction built in. but does it have Noise Reduction dedicated mic ?
Noise cancellation has a dedicated mic.
I think someone created a mod to disable that on the nexus one. Pretty sure you can do the same to the gn.
Yeah I'm voice issues with my S2 when Noise Reduction is enabled, so I have to disable manually it on every call. Would be more convenient if it can be disabled permanently on ICS, without having to root.
I have recently switched from S3 to Note 2 and I have experienced a significant change in gtalk sound. Now it's significantly darker, and my partner and I miss the slight bright noise in our audio conversations. She's had no changes on her phone and besides, before selling my S3 we had the chance to test both devices at once and clearly the sound was worse in note 2.
I had tried several things regarding microphone gain: N.E.A.K. kernel with wolfson audio control, alsa mixer, default_gain.conf tweaking, with not very noticeable changes.
I figure out the problem is not mic gain but noise cancellation. There's an option in stock phone app to switch it on or off during a call. Also some apps for sound recording have that option (Asr from play store).
Is there any way to disable noise cancellation under gtalk? Maybe in a configuration file? Does anybody know where that file is? Or maybe there's a way to disable noise cancellation globally?
Thanks for your help!
Have you tried disabling noise cancellation from your phone settings? Not sure if it will affect gtalk, but it's worth a shot.

Hello all.
With other, older cellphone models, I used to have the leisure habit of recording audio (messages or files) to save/send live songs recordings. Granted, the quality was never impeccable, but at least I could hear the bass notes (or their distortion whenever the sound source was near enough).
Now, whatever method of noise reduction (NR) the Moto G5S employs is ruining this experience. Hearing the bass is crucial for samba and capoeira. The NR kicks in after 2 or 3 seconds from the beginning of the recording. Does anyone know of a way to disable it?
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
