After the update to Android 9 i'm facing issues with the audio quality in all applications, specially in the video recording. The audio is not clear and appears to have a really bad noise reduction filter or volume dump applied. Before the audio was crystal clear. Now sounds like a bad encoded MP3 file with 96kbits.
Looks like a bug, but if Motorola/Lenovo have the Idea to implement the noise reduction feature, they must give the option to turn it off.

Thanks for posting. I would first check and make sure all apps are up to date in the Play Store. May I know what apps did you use? Do you still have the old video file to compare with your new video? Does it happen using the default camera app? I would appreciate if you can share me 2 samples showing the comparison of your old video and the new video. Thanks.

All the apps are updated. The same audio issue happens in all applications.
The examples recorded with the default camera app:
Android 8.1 - Audio test
Android 9 - Audio test
Same location. The ambient sounds and the voices disappears.
(Sorry for the southern lapwings video haha)

Thanks for the sample video. I can hear the difference between those two. Let's try isolating the software as one of the factors. Can you please check if the Moto camera is up to date in Play Store? Make sure other apps are up to date as well. Once done, try booting the phone in safe mode and see if there's any improvement with the video audio.
To Enable Safe Mode
1. Press and hold the Power button until Power off comes up on the screen.
2. Touch and HOLD Power off on the screen until reboot to safe mode appears.
Just turn off and on the phone to boot back to normal mode.

I've updated all the apps including the camera app and tested in safe mode. I have noticed that just ONE application its not affected by this issue, the audio recording software made by Sony. The other apps (Camera App, Instagram, WhatsApp and other video apps) still with this poor quality sound.
By the way, the factory reset doesnt work to solve this problem, my friend had tested without success.

Thanks for your reply. Appreciate those things you've tried. May I know what's that Sony app? Also, when you factory reset the phone, did you restore your apps right away?

I think this app can manage the mics directly.
About the reset, i'd started from zero. No data restore.

Thanks for your cooperation. I haven't asked this, have you tried testing the hardware test (Moto Help app > Diagnosis > Hardware Test> Microphone). Let me know how's the sound quality.

I'd like to share this. Can you share a bug report when you experience this again?
To capture Bug Report:
Go to Settings ->Developer options -> Enable USB debugging > Toggle On
Enable Settings -> Developer options -> Enable Bug Report shortcut > Toggle On
Once the issue is reproduced: Go to Settings -> Developer options -> Click on take bug report or Press Power button and then choose Bug Report from the Power-down menu.
Wait for some time until the bug report is collected. It takes around 3 to 4 minutes to collect the Bug Report.
Then upload the BugReport to your personal Google Drive and then share the link to the bug report on the forums in a reply.
Provide observations of what you saw happen right before the bug report was taken. Please indicate the local time when you observed the behavior.
To enable developer options:
1. Go to Settings > About phone > Build number
2. Tap Build number seven times. After the first few taps, you should see the steps counting down until you unlock the developer options. Once activated, you will see a message that reads, “You are now a developer!”
3. Go back to Settings, where you’ll find a Developer options entry in the menu
