How to completely disable the noise maker on Xiaomi: 5 proven ways

Noise cancellation on Xiaomi devices is a useful feature for calls and recordings, but sometimes it works too aggressively, cutting off the voice or creating a “robot” effect. Redmi/POCO When talking on speakerphone or while streaming, in this article, we'll look at all the ways to turn off the noise maker -- from the standard settings. MIUI to the hidden engineering menus.

It’s important to understand that the manufacturer doesn’t always provide a direct option to turn off noise cancellation. In some models (for example, Xiaomi 13 Pro or Redmi Note 12), the feature is integrated at the firmware level and requires workarounds. We tested the methods on current versions of MIUI 14/15 and assembled working solutions even for budget devices.

1. Disconnecting noise emitter in standard MIUI settings

So, to start with the obvious, basics testing, and in the latest versions of MIUI, noise reduction can be hidden in different sections depending on the model, and here's where to look.

📱 For smartphones: Settings → Sound and vibration → Improvement of sound → Noise suppression on calls. Switch the slider to "Off."
🎧 For AirDots headphones: Connect the headphones, then go to Bluetooth Settings → Settings of the device (cog next to AirDots) → Noise suppression.
🎤 For microphone: In some models (e.g, POCO F5) The option is hidden in the camera settings → Additionally. → Improvement of sound.

If you don’t have Noise Reduction on your menu, don’t worry, it means the feature is managed at the firmware level. For example, in Xiaomi 12T and Redmi K50, the option only appears when you call actively (click on three dots in the call interface and select “Mic settings”).

For advanced users, there is a way to turn off the noise emitter through an engineering menu, which works on most Qualcomm Snapdragon processor devices (e.g., POCO X5 Pro, Redmi Note 11 Pro+).

Instructions:

Open the Phone app and type the combination: ##36446337## (or #4636### for older models).
Go to the Hardware Testing section → Audio → Mic.
Find the Noise Suppression or NS (Noise Suppressor) settings and set the Disable value.
Save the settings and restart the device.

If the combination does not work, try an alternative method:

adb shell settings put global noise_suppression_enabled 0

This command must be entered through ADB (read more about ADB settings in Section 4).

Make a backup copy of the data

Charge your phone at least 50%

3. Disable noise reduction for specific applications

Sometimes noise-molding only interferes with certain programs, such as Discord, Zoom or TikTok, in which case you can turn off the processing of the sound selectively.

Ways:

🎮 For games and streams: In the application microphone settings (for example, in PUBG Mobile or Kwai) search for the “Voice Processing” option and turn it off.
📹 For the camera: In camera settings → Video → Audio Settings (available on Xiaomi 13 Ultra and new flagships).
💬 For messengers: In Telegram or WhatsApp, noise cancellation is controlled at the application level – check the call settings.

If the option is not in the interface, try resetting the microphone permissions:

Go to Settings → Applications → Permissions Management → Microphone.
Find the problem app and turn off access to the microphone.
Run the app again and give access to the microphone again.

Why does the noise make itself turn on?

Xiaomi devices with MIUI 14+ have an Adaptive Noise Canceling feature that automatically activates in noisy conditions (such as on the street or in transport). It turns off via Settings → Special Features → Audio → Adaptive Sound.

4.Using ADB for deep shutdown

If standard methods don’t work, you’ll need to connect to the device via Android Debug Bridge (ADB), which requires a computer and minimal technical skills, but gives 100% results.

Step-by-step:

Download ADB Tools and unpack the archive.
On your phone, activate Developer Mode (7 times click on the MIUI version in Settings → About Phone).
Enable USB debugging in Settings → Additional → For developers.
Connect the phone to your PC and enter in the command line (in the folder with ADB):

adb devices


adb shell settings list | grep noise

This command will show you all the parameters associated with noise reduction.

adb shell settings put global noise_reduction_level 0


adb shell settings put global voice_communication_noise_suppression_enabled 0

Once you've done the commands, restart the device. To return the settings, replace 0 with 1.

💡

If, after the noise is removed, ADB The sound is too quiet, check the microphone gain with the command adb shell settings put global. mic_gain 6 (significance 1 before 10).

5. Firmware and modified MIUI: radical methods

On some devices (especially custom firmware like Xiaomi.eu or Pixel Experience), noise cancellation is only disabled through editing system files, a method that is suitable for power users and requires an unlocked bootloader.

Options:

🔧 Editing build.prop: Add a line persist.audio.fluence.noise_suppression=false.
📁 Removal APK: Delete the file. /system/priv-app/MiSoundRecorder/MiSoundRecorder.apk (responsible for sound processing).
🔄 Reset to factory: In extreme cases, reset via Fastboot with the option turned off noise_suppression firmware.

Warning: Any changes to system files may result in loss of warranty or unstable device performance. Create a full backup via TWRP or OrangeFox before experimenting.

💡

On devices with a MediaTek processor (e.g., Redmi) 10C) engineering menu and ADB-And the noise-cancellation commands often don't work, and in that case, all that's left is the firmware or the use of an external microphone.

6. Alternative solutions: if nothing helps

If you can’t turn off the noise, consider the workarounds:

FAQ: Frequent questions about noise reduction on Xiaomi

❓ Why the sound became worse after the noise was turned off?

This is normal: noise cancellation not only removes background noise, but also improves overall sound quality through processing algorithms. Without it, the microphone transmits raw sound, where all defects are noticeable - echo, hiss, low volume. Solution: Use an external microphone (for example, Lavalier or Boya BY-M1). Set a uniform volume level through Settings → Special features → Audio → Mono-audio.

❓ Can you turn off the noise for just one application?

Yes, but not on all devices. On Xiaomi 13/14 with MIUI 15, this is done through Settings → Apps → Permissions Management → Microphone → Additional. For older models, AppOps (requires root) will help. Alternatively, use a second call app (like Google Phone), where noise cancellation can be disabled separately.

❓ The noise is turned on itself after the update. MIUI. What do you do?

This is a problem after updating to MIUI 14.0.4+ and MIUI Solutions: Reverse to the previous firmware version via Fastboot. Install the Disable Noise Suppression patch via Magisk (requires root). Contact Xiaomi with a complaint - sometimes they release a hotfix for specific models. List of infected firmware: V14.0.4.0.TMBCNXM (Redmi Note 12), V15.0.1.0.TLCCNXM (POCO F5).

❓ How to check if noise reduction is working?

Make a test call to another phone and say, "Clap your hands next to the microphone -- if the sound is muffled, the noise is active. Turn on background music -- if it's barely heard on the record, the processing works. Use the Spectroid app to analyze the frequencies -- noise cancellation cuts down on high frequencies (above 8 kHz)."

❓ Is there a difference between noise reduction on Xiaomi and POCO?

It is the same function because POCO base-based MIUI. Exception: models POCO F-series (e.g., F-series, POCO F5 Pro), where sometimes additional audio settings are available in the proprietary application POCO The difference may be in: Location of menu items (on the POCO Processing algorithms are on flagships (e.g. Xiaomi) 13T) noise reduction is more aggressive, the presence of branded chips (for example, POCO Audio Boost in Games).

If none of the methods worked, perhaps the problem lies not in noise cancellation, but in the hardware malfunction of the microphone. In this case, contact the Xiaomi service center - the microphone diagnostics cost ~ 500 rubles and takes 1-2 days.

⚠️ Note: On devices with HyperOS (new firmware for Xiaomi 14 and newer), the methods of disabling noise cancellation may differ. → The phone.
