How to Remove Your Voice When Recording a Conversation on Xiaomi: From Filters to Professional Apps

Recording phone conversations on Xiaomi smartphones is a useful feature, but often users face a problem: their own voice sounds louder than the interlocutor, interferes with perception or makes the recording unusable. MIUI And fortunately, there are a number of ways to solve this problem, from built-in tools to third-party applications with advanced noise reduction algorithms.

Many people mistakenly think that it is enough to simply reduce the volume of the microphone in the settings, but this does not always work: Xiaomi by default optimizes the recording to the voice of the interlocutor, not to the background sound. 5 working methods, from basic to professional, that will help you to remove or at least significantly mute your voice in the recording. MIUI 14/15 It is compatible with most models: from the budget Redmi Note 12 before Xiaomi's flagships 13 Ultra.

Why Your Voice Is Louder Than Your Encounter: Technical Reasons

The problem of uneven voice volume in recordings is associated with three key factors: the design of microphones, the algorithms for processing sound in the recording. MIUI And the physical location of the sound source. Let's take each of them apart.

First, Xiaomi smartphones use a dual microphone system: the main (bottom) and noise suppression (top) both activate when recording a conversation, but the main microphone is closer to your mouth, so it captures your voice with a greater amplitude, while the interlocutor is played through a speaker that is located 5-15 cm from the microphone – the signal weakens.

Secondly, MIUI By default, it applies automatic volume normalization (AGC — Automatic Gain Control: This algorithm amplifies quiet sounds (like the voice of the person you're talking to) and mutes loud ones (your voice). AGC It often works incorrectly because it cannot accurately separate speech from background.

Finally, don't discount the acoustics of your environment, because if you're recording a conversation in an echoed room or outdoors with the wind, the microphones will pick up additional noises that will mix with your voice and amplify it in the end recording.

⚠️ Note: On Xiaomi models with stereo recording (e.g. Mi) 11T Pro or Redmi K50) The stereo microphones capture sound from different directions, and your voice is hitting two channels at once, which creates a double echo effect".

Method 1: Using a built-in sound editor in MIUI

If you need to quickly mute your voice in an existing recording, you can use the standard application Records (or Recorder depending on the version). MIUI). It allows the use of basic noise reduction and normalization filters.

Instructions:

1. Open the Records app and select the file you want.
2. Click on the edit icon (pencil or three dots) →"Edit").
3. Go to the Effects or Filters tab.
4. Activate options: 🔇 Noise suppression (reduce background sounds, including your voice) 📉 Normalization (calms up the volume) 🎚️ Equalizer (reduce the slider at 200-500 Hz – there is usually your voice)

Save the modified version of the recording.

This is a method that's good for a slight improvement in quality, but it's not going to solve the problem dramatically. MIUI weaker specialized applications, and with strong noise reduction, the intelligibility of the interlocutor’s speech may suffer.

⚠️ Note: On some models (e.g. Poco) X5) The effect tab may not be available, so move on to the next method.

Method 2: Third-party applications for noise reduction recording

If built-in tools don't work, you should look at specialized conversation recording apps, which offer advanced audio processing algorithms, including voice separation, which suppress noise and echo.

Top.-3 apps:

For the best result, we recommend Cube Call Recorder, which uses VoIP processing technology, which was originally developed for overwhelming echoes in Internet calls.

1. Open the application settings.
2. Go to Audio Settings → Noise Suppression.
3. Select Aggressive (Aggressive Suppression) mode.
4. Enable the Separate Speaker & Mic option.

Important: To work properly, these applications need to be given permissions to record sound and access the microphone. MIUI 14+ This is done in the settings → Annexes → Permits → Special access → Sound recording.

Method 3: Manual editing of PC recording

If the recording quality is critical (for example, for court cases or important negotiations), it is better to process the file on your computer with the help of professional audio editors.

The best programs for this task:

• 🎛️ Audacity (free, cross-platform) – suitable for noise removal and normalization.
• 🎧 Adobe Audition (paid) – advanced voice sharing tools.
• 📊 OCenaudio (free) – a simple interface with support VST-plug-ins.

Step-by-step instructions for Audacity:

1. Import the record through the file → Open up.
2. Select the area with your voice (for frequency analysis).
3. Move to Effects. → Noise reduction and settings: Noise reduction level: 12–15 dB Sensitivity: 0.8–1.0 Anti-aliasing: 3–5

Effects. → equalizer

200-600 Hz

400-800 Hz

WAV

To split your voices in Adobe Audition, use the DeNoise tool (Effects tab). → Noise Reduction/Restoration), Then use Center Channel Extractor to highlight the conversational speaker.

⚠️ Attention: When aggressively processed, audio editors may have a metallic tint in the voice of the interlocutor. Always save the original recording and experiment with a copy.

💡

Before processing in Audacity, zoom in on the sound wave (mouse wheel or mouse wheel) Ctrl+1). This will help to highlight areas with your voice for effects.

Method 4: Hardware solutions – external microphones and headsets

If software methods don’t work, hardware solutions are worth considering, and they are especially relevant for users who regularly record conversations (such as journalists or lawyers).

Options:

• 🎤 External lavalier microphone (e.g. Boya) BY-M1 Sony ECM-CS3). Connected through a 3.5 mm connector or USB-C (The microphone is attached to the person, and your voice is recorded from a greater distance, which reduces the volume of the recording.
• 📞 Headset with noise cancellation (for example, Xiaomi FlipBuds Pro or Sony) WH-1000XM5). The built-in microphones of these devices are optimized for overwhelming background noise, including your voice.
• 📱 Separate recording adapter (e.g. iRig Pre 2) allows you to connect two microphones: one for your voice, one for the other, followed by mixing.

To connect an external microphone to Xiaomi:

1. Connect the microphone to a 3.5mm connector or USB-C (Use an adapter if necessary USB-C → 3.5 mm).
2. Go to Settings. → Connected devices → Microphone settings.
3. Choose the external microphone as the primary source of sound.
4. Run the recording through the standard Records app or third-party software.

The advantage of hardware is that it has minimal quality loss and no post-processing, but it's expensive and not always convenient for spontaneous recording.

Method 5: Configure system sound parameters in MIUI

In some cases, the problem can be solved without third-party applications by changing the hidden sound settings in the app. MIUI. This method requires activation of the developer mode and work with the engineering menu.

Instructions:

1. Activate Developer Mode: Go to Settings → About the phone. Press 7 times on the version. MIUI. Enter the password from your Mi Account if required.

Settings → Additional → For Developers

USB debugging

ADB

adb shell settings put global mic_gain 0.7

This command reduces the microphone gain to 70% of the standard value.

adb shell am start -n com.android.engineermode/.EngineerMode

Go to the menu to Hardware Testing → Audio → Mic Test and manually adjust volume levels.

These settings affect all recordings, including calls and videos, and if the voice of the person you're talking to is too quiet after the changes, return the settings to the standard values with the command:

adb shell settings put global mic_gain 1.0

⚠️ Attention: Incorrect settings in the engineering menu can cause malfunctions in the microphones. Before experimenting, back up your data via Settings → System system → Backup.

💡

Change the parameters of the microphone through ADB — The most effective way for root-right users, without which the settings will reset after the reboot.

Frequent Mistakes and How to Avoid Them

When you try to remove your voice from a recording, users often make mistakes that only make the result worse, and let's look at some of the most common ones.

Mistake 1: Excessive noise cancellation

Many people think that the more noise cancellation is done, the better, and in fact, it leads to robotic voices that become metallic and hard to understand, and the optimal noise reduction level in Audacity is 12-15 dB, and in Cube Call Recorder, Moderate mode.

Mistake 2: Recording in a noisy room

If you're recording a conversation outside or indoors with an echo, no app can properly separate your voice. Solution: record in a quiet room with upholstered furniture (it absorbs sound) or use a directional microphone.

Error 3: Ignoring file formats

Keeping the record in format MP3 With a bitrate of 64 kbps, you'll lose quality. WAV (uncompressed FLAC. Only after processing, convert to MP3 192–320 kbit/s.

Mistake 4: Setting the microphone to the eye

Changing the microphone settings through the engineering menu without testing can make the voice of the person you are talking to become inaudible. Always record the test fragment after the changes.

Mistake 5: Using a single method

No one method is perfect the first time, and combine Cube Call Recorder recording with Audacity processing, which will be better than any method alone.
