edit noise reduction algorithm - Xiaomi Mi 6 Questions & Answers

Is it possible to change the noise reduction algorithm? Namely, making noise monochrome, not colored.
In ios done exactly so, and it looks not bad.
Are there any developers who can do this?

Any fix for sound quality???

As we all know the sound quality when you take a video is terrible... Is there anyway to edit the video to fix the sound, or is there something that can be done to have good sound quality when taking a new video???
Editing the video after its taken would be pointless, you can't increase the quality once its already recorded. The only thing I can think of is being sure to use the highest recording quality setting. I'm not sure if it helps the audio quality any though. We are limited my the quality of the microphone that comes with the phone.

[Q] Video Recording Pointers

K guys, I'd really like some pointers/advice on how to improve video recording at concerts. Any settings I can change to a) prevent audio distortion and noise and b) prevent that terrible white burn that makes faces unrecognizable caused by the lighting.
I was at a concert this weekend with pretty good seats, about 15 rows from center stage, and the faces are barely visible..covered by an annoying glow.
I know bass also complicates the audio portion so I don't expect perfection but I would like to know if there are any steps I can take before or after recording to improve the overall quality whatsoever. Thanks in advance.
Please help..
I go to a lot of live events and honestly the lack of ability to record live performances is killing me...
I'd be willing to start a bounty thread for someone who has the ability to change this audio issue.. The video mods I've found easy to do through the media profiles.xml file, but the audio in loud environments is just horrible.

What exactly is Voodoo Sound/Color?

I keep seeing people wanting Voodoo Sound or Voodoo Color and I don't know what it is? Could someone explain it to me? And why people would want it? I want to know how much better it makes our Epics by having them. Thanks!

Voodoo sound is kind of like an audio enhancer..bass and volume booster hifi sound quality etc. Voodoo color allows you to change the deepness of colors and shadows. As well as tune the rgbs and change the color warmth and coolness basically tuning an lcd tv for your phone

Voodoo lets you enhance your phones display/audio features by making whites whiter and darks darker. It also lets you enhance your phones audio for listening to music. Do a search around the forum, you will find more in depth info.
Big Goron always beats me by second.

High-pass filter on audio

Hi there, fellows HOX users,
There were several topics about HOX's poor audio quality when capturing video or recording through voice apps, but still, there weren't any solutions how to solve the lack of frequencies down below ~100-200hz.
I have experience working with sound production, recordings, so I know that these limitations are only made by software. In that case, there must be some kind of solution to improve audio recording quality and enjoy HOX at 100%.
I tried editing srs_global.cfg (found in /system/etc/soundimage) (there was a guy who tried to improve the sound of the phone's loudspeaker and he kinda managed to do it by editing the file), by changing high-pass filter frequency in every "device"
//BLOCK: (srs_hpf_0) HiPass - Device 0
//=-=-=-=-=-=-=-=-=-=-=-=-
srs_hpf_0:hipass_order = 4 // Filter Order -
srs_hpf_0:hipass_frequency = 60 // Filter Frequency -
srs_hpf_0:hipass_is32bit = 1 // Filter Precision (16bit when 0) -
srs_hpf_0:hipass_skip = 1 // Skips High Pass Filter when true - toggle

but there aren't any results.
I don't really understand the types of devices and that they do (WOWHD, TruEQ, CSHP and so on).
Maybe there is any other cfg files who process audio input, because it's the same high-pass filter when recording on internal mic and with external 3.5mm mic.
Let's try to solve this problem everybody, because, as HTC support said
HTC is not designed for capturing things in loud environments

Yeah, whatever... It can do it!

Don't mess with HPF, REALLY DON'T!
I have been experimenting with SRS trumedia 51 and music, HPF messes up when enabled!
these settings you have posted are from SRS_global which won't really do much, install musicBox and you can get SRS working...
There is a reason why you sould not enable HPF without know what values are right, I tried this and it made a mini explosion noise (a sqeek then a loud POP) when starting audio, I highly recommed you do not mess with it. Anyways, SRS will NOT do anything with audio recording, your best place to find audio recording values are in the media_profiles.xml in /system/etc
SRS has nothing at all to do with recording audio, only to output the SRS effect.
I hope this info helps
WOWHD is SRS WOWHD, this is a sound effect which enables a true surround sound experience.
TruEQ is SRS's native EQ settings, not much to say here...
CSHP is SRS CS Headphone. Or as I would like to call it, Dolby Digital 5.1 (Because it IS the exact same effect) (CSHP is only used in srs_truemedia_51) (HTC Enhancer uses this file)
Thank's for your answer.
I can't understand, how nobody is interested in improving audio recording quality, when it's obvious that it's a software limitation thing.
We have an almost perfect phone with good camera, but we can't fully enjoy watching and LISTENING recorded videos, because some "clever" people in HTC decided that it's normal to high-pass the mic and put a compressor on it, without any gain control - in result we have a tragic audio from loud concerts and even LOUD voice conversations (where people are sceaming a little bit).
Maybe someone has a solution?
Maybe HTC will offer switching to a ****ty iphone, which has almost perfect audio recording quality (for a phone)?!

Pixel camera error urgent help

MAN GO HIDE YOUSELF
nothing is wrong with your camera
It's a scam no need to click on it.
Sent from my Pixel using XDA-Developers Legacy app
A scam?
Im lost, was there a link that was removed that i cant see?
The video that was posted (That i can see) definitely seems like you have excess white/background noise. Are you running a kernel? if so return to stock. It seems almost like a noise cancellation error, you can read about it in a few places, just google "pixel microphone problems"

Do you mean excess video noise or sound noise?
In lowlight, you can't expect the video to be free of noise. It has to boost the ISO to keep the video going at the full 30FPS, boosting ISO leads to visual noise.

I think He's talking about the audio noise. When you listen to that video, It sounds like his phone mic is in front of a fan.
