How to Make a Louder Mic on Xiaomi: From Simple Settings to Hidden Features

Have you noticed that the person who is not hearing you during calls or recording your voice is too quiet? The problem with low microphone volume on Xiaomi smartphones is common – especially on Redmi Note models, POCO The reasons can range from incorrect settings to hardware limitations, and in this article we will look at all possible ways to amplify the microphone, from basic to advanced, including hidden features. MIUI and engineering menu.

It is important to understand that some methods require superuser rights (root), and others can affect the sound quality (for example, background noise will appear).We will note the risks and give recommendations on how to avoid them. If you use a microphone for streams, podcasts or video calls, pay special attention to the sections on noise cancellation and setting Voice Changer.

So let's start with the simplest solutions that don't require technical skills, and gradually move on to the more complex ones. If your Xiaomi is older than 2020, some menu items may differ, we'll show you alternative paths.

1. Check the basic microphone settings

Before digging deep, make sure the problem isn't with the trivial settings. Often users accidentally turn off the microphone or reduce its sensitivity through system settings.

Open the Settings. → Annexes → Permits → Microphone and check:

• 🔍 Applications that use the microphone (e.g. WhatsApp, Zoom, TikTok) are given all permissions.
• 🔊 There are no restrictions for system applications (e.g. com.android.phone for calls).
• 📱 There is no cross-out microphone icon in the top notification bar (meaning it is turned off globally).

Also look at the settings. → Sound and make sure that:

• 🎙️ The slider "Loudness of the microphone" (if any) is at its maximum.
• 🔇 Do Not Disturb or Quiet Mode not activated.
• 📞 In Call Settings (Settings) → SIM-maps and mobile networks → Call settings) No noise cancellation enabled (sometimes it suppresses voice too aggressively).

If the volume hasn't changed after these manipulations, move to the next section. 12/13 series POCO F4/F5 There may be no separate microphone volume control, in which case alternative methods will be required.

2. Cleaning microphone holes and checking hardware problems

One of the most common causes of a quiet microphone is contamination of the holes, and dust, pile from your pocket or cosmetics (such as tone cream) can block the sound signal. Most Xiaomi smartphones have microphones located:

• 📍 Bottom of the case (main microphone for calls).
• 📍 Up next to the speaker (an additional microphone for noise reduction).
• 📍 On the back (some models, for example, Redmi Note 10 Pro).

For cleaning:

1. Turn off the phone and get it out. SIM-card (if the microphone is near the tray).
2. Use a soft brush (for example, for drawing) or a toothpick with cotton wool soaked in alcohol.
3. Blow the holes with a spray of compressed air (not your mouth!).
4. Check the microphone after drying out (10-15 minutes).

💡

Do not use metal objects (needles, pins) - they can damage the protective mesh of the microphone. If the contamination is severe, contact the service center.

Also make sure that the problem is not physical:

• 🔧 Check if there were any falls or moisture (even if the phone turns on, the microphone could have been affected).
• 🔊 Connect headphones with a microphone – if the sound becomes normal, the problem is in the phone’s main microphone.
• 📱 Try recording voice through another app (such as Voice Recorder or Voice Recorder).

⚠️ Warning: If the microphone is still quieter or wheezing after cleaning, it may indicate membrane damage. In this case, self-repair is not recommended - contact the authorized Xiaomi service.

3. Customize the microphone through the engineering menu (without root)

The Engineering Mode allows you to fine-tune microphone settings, including signal amplification and noise reduction filters.This method works on most Xiaomi smartphones, but the interface may vary depending on the version. MIUI.

To open the engineering menu:

1. Open the phone app.
2. Enter the code ##4636##
3. Select "Phone Information" (or "Testing" on newer versions).
4. Scroll down and find "Microphone" or "Audio".

In the microphone section you will see several parameters:

When you change the settings, be sure to restart your phone to make the settings work. If you then complain about an echo or metallic sound, return Noise Suppression to "Default".

4.Use of applications to enhance microphone

If the system settings don't work, you can use third-party apps that work as a middleman between the microphone and the applications, amplify the signal and filter the noise.

• 🎤 Microphone Volume Booster is a simple real-time volume-adjusted booster, suitable for calls and video calls.
• 🔊 Voice Changer & Audio Effects – not only enhances sound but also uses effects such as removing wind noise).
• 📱 Wo Mic – transmits sound from microphone to PC Wi-Fi/Bluetooth, where it can be further processed.
• 🎧 Krisp — AI-Noise reduction for calls (works in Zoom, Discord, Teams).

Example of Microphone Volume Booster setup:

1. Download the app from Google Play.
2. Start and give permission to access the microphone.
3. Move the "Mic Gain" slider to +15–+20 dB.
4. Enable the option of "Remove Noise" (if any).
5. Select an app that needs to be strengthened (like WhatsApp).

Note that some applications (such as Wo Mic) require a PC connection and driver installation, and they can drain the battery faster because they are constantly processing the audio stream.

⚠️ Note: Microphone amplification applications may conflict with system services MIUI. If after installing the booster, the sound in the calls disappeared, clear the cache of the com.android.phone application in the settings.

5. Microphone setting for specific applications

Sometimes the problem with a quiet microphone only manifests itself in certain applications (for example, in Discord or TikTok), in which case you need to configure the sound parameters directly in the application itself.

For Zoom/Teams/Google Meet:

• 🎤 Before calling, go to Settings. → Audio".
• 🔊 Select "Use original audio" (disables voice compression).
• 📱 Turn on the Noise Suppression option only if the background is really noisy.

For Discord:

• 🎧 Go to "User Settings" → Voice and video".
• 🔊 Set the "Mic Sensitivity" on the -20 dB.
• 📱 Turn off "Automatic volume control".
• 🎤 Enable Krisp Noise Suppression (if available).

For TikTok/Instagram:

• 📱 Before recording the video, tap the Microphone icon at the top of the screen.
• 🔊 Select "External microphone" (even if only built-in microphone is connected).
• 🎤 Make sure that the application settings allow access to the microphone.

If you stream from your phone (like Twitch or YouTube), use the Streamlabs app for Android, which allows you to separately adjust the volume of the microphone and games, as well as apply noise reduction filters.

💡

In some applications (such as WhatsApp), the microphone settings are reset after the update. Once you install the new version, check the audio settings again.

6 Advanced methods: root access and modification of system files

If none of these things worked, there are still radical methods -- but they require unlocking the bootloader and obtaining root rights -- that are warranty-free and can cause the phone to run insecurely, and only use them if you're an experienced user!

Method 1: Editing mixer_paths.xml

This file contains your Xiaomi audio chip settings to change:

1. Get root access (for example, through Magisk).
2. Install a file manager with root support (such as Root Explorer).
3. Cross the path: /vendor/etc/mixer_paths.xml (or /system/vendor/etc/ older versions).
4. Find the lines from Mic and change the value settings for RX Digital Volume (set the value from 85 to 100).
5. Save the file and restart the phone.

Method 2: Installation of a custom core

Some custom cores (e.g., FrancoKernel or ElementalX) have advanced audio settings. EX Kernel Manager or FKM Headphone & Mic Gain section will appear where you can set up the amplification to +30 dB.

Method 3: Magisk modules

The Magisk repository has modules for improving sound:

• 🔊 ViPER4Android FX — powerful equalizer with microphone settings.
• 🎤 Audio Modification Library – Increases the microphone’s maximum volume.
• 📱 JamesDSP – sound processor with microphone input support.

⚠️ Attention: Incorrect editing mixer_paths.xml This can cause a complete loss of sound on your phone.Before you change it, back up your file (2023+ System files can be protected by dm-verity, and their change will lead to bootloop.

7 Hardware solutions: external microphone and service center

If the software methods have not yielded results, two options remain:

1. Connect the external microphone.
2. Contact the service center.

An external microphone can be connected to:

• 🎤 A 3.5mm connector (if you have one on your model) will fit any lavier microphone (e.g. Boya) BY-M1).
• 🔊 Bluetooth (e.g. Sony) ECM-LV1 Or Rode Wireless Go. II).
• 📱 Through USB-C adapter (e.g. Shure) MV7 adapter).

To connect to USB-C may be required:

• adapter USB-C → 3.5 mm (e.g. from Xiaomi or Anker).
• Incorporation of the regime "USB-audio" in the developer settings (Settings → The phone. → Version. MIUI — Tap 7 times, then go back to Settings → Additionally. → For developers → USB-audio).

If you are sure that the problem is a hardware malfunction, contact the service.The cost of replacing the microphone on Xiaomi:

Before the service visit:

• 📱 Make a backup copy of the data.
• 🔧 Check if they use original parts (noise reduction may be worse on non-original microphones).
• 💰 Ask for a warranty for repairs (usually 3-6 months).
