Help reducing mic gain - Xiaomi Redmi Note 7 Questions & Answers

Hi, I have a Redmi Note 7 and audio recording quality is awful when it comes to loud music. I tried setting "unprocessed source" from open camera, but quality is still terrible.
Which settings should I change in system/vendor/etc/mixed_paths.xml in order to reduce mic gain, hoping that will help for audio distortion?
I get lost with ADC1, DEC1, RX1 etc.
Thanks!

Video recording sound too low

I tried to video record my son while he was speaking but at playback I could hardly hear his voice. He was about 1 meter apart and I could hear him as if he was 20m away. My voice sounded ok though. I assume that the microphone used for audio recording is the same as the phone mic with higher volume control.
Is everyone experiencing the same?
Also, Ihaven't found any controls to configure audio levels for different circumstances (i.e. phone ringer, speakerphone, speaker during conversation, etc.) Is it necessary to only configure volume when you are in that area (i.e only during conversation or during playback) and not all at once in a special control panel? (I hope you understand the last part as I don't know how to explain better)
I also feel that the playback volume for recorded video is too low (even on max volume). The audio quality is also not as good as I would hope. I have yet to test playback on a PC though.
Unfortunately anything related to Desire HD sound is low at the bottom line no matter recording or speaker it is.
agreed that recording volume is too low. But one thing i did find is that when you hold your phone to record, the natural position where your right hand holds the phone actually covers the microphone (well at least for me). So make sure your hand isnt covering that and it might improve sound a little.
But when i playback a recording on my laptop it sounds ok when i max the volume.. definitely audible.
Im also getting this low mic problem, made sure i was not covering mic, still low volume. Even took the case off, still no joy, cant believe they did not test this before launch
Please HTC sort this out
After playing back recorded videos on my laptop, i'd agree with SupremeBeaver that the volume is ok. The sound quality seems much better too, so i'm not too fussed now

Sound quality through headphones

It is noticed that while listening through headphones that the sound is being affected by some sort of 3D/spacial/EQ process that might give the impression of "punch" for movies but at the expense of phase-y sounding vocals and smeared high notes for music.
Yikes. Thst stuff is not good for music quality. No way to turn off? The settings options seems kind of scarce.
After playing around with various music players and headphones it seems that the audio is now OK.
Not sure what happened. It may have been a headphone jack issue. Audio sounds great now.
Oooops!
There is an issue with sound quality. Compared it to a Rockbox'ed Sandisk Clip Zip with a very wide stereo track 2-channel stereo track (fyi -- Brook Benton's "Kiddio" 1960). There is some EQ bast boost and high frequency crossfeed that narrows the stereo separation. I'm going to boot from CM and see if the problem persists.
For video I would not notice the issue, but could get to me listening to music with my Klipsch S4 buds.
Update:
It is not bad. Seems part of the issue is low gain which can be increased with Volume+ or other similar app function.
Volume+ did the trick for me. Jamming to some Coheed at the moment. Sounds as good as my other tablets now
The problem was never with volume -- I think stock has plenty of volume for driving Audio Technica ATH-900x. The problem is with some sort of audio processing that affects the soundstage and frequency response.
I am not hearing it using the Google player app. Gain is not the same as volume. Both need to correlate or weak quality.
SRS processing is used and applied at the headphone output. See HD+ file \system\etc\srs_processing.cfg
This is what I use, have my settings set to Jazz "my preference", audio sounds great, not talking about low resolution MP3's.

I understand the config issue, but I am not hearing it. I should hear the sound manipulation with cymbal decay as example, but not hearing it. Weird.
Playback in CM 10.1 has the correct stereo image.
so am I
so am I ,after checking

Is it possible to set microphone volume?

I bought this unit: http://www.amazon.com/gp/product/B0151KNXJ8?psc=1&redirect=true&ref_=oh_aui_detailpage_o00_s00
I know it is a known issue that the microphone quality is bad, but I'm not willing/able to open the device and tinker around with the motherboard. The microphone quality would be acceptable to me if it would just be a bit louder (increase microphone gain). Is there any way we can get access to a volume control that would just record the sound a bit louder? Any other software based options to improve the mic quality for phone calls and voice commands?
I have this one in one car and a KD-C0224 in another car. In both of them the speech quality has improved dramatically after I connected external microphones that were included in their boxes. The sound quality of the built-in Pumpkin microphone is indeed pathetic.

How do you record loud audio without clipping?

I like to record video and audio at live concerts. Whenever I record video with the 6p, the audio comes out pretty decent w/ no clipping.
However, when I use an audio recorder, such as the Sony Audio Recorder and Field recorder, i get tons of clipping. I've tried turning down gain and enable clip protection, but the recording quality always sounds overloaded whenever the bass hits. The audio meters in it doesn't show that it reaches the 'red' but the resulting audio is still distorted.
How can i record audio w/ the 6p and get it sounding as good as the audio in the videos i record?
