Xiaomi recorder does not record sound well: what to do if the voice is barely audible?

You turned on the recorder on Xiaomi smartphone, but the recording turned out quiet, with noise or no voice at all? The problem is familiar to many users, from owners of budget Redmi to the flagship Mi 13 Ultra. The reasons can lie in software failures and hardware malfunctions of the microphone. In this article, we will analyze all possible scenarios, from basic settings to diagnostics hardware.

It's important to understand that silent recording isn't always a failure, and it's often the fault of clogged microphone holes, incorrect sensitivity settings, or conflicting applications, and we've put together 7 working methods to help you get that sound back to the center, without going to the service center, and start with simple steps and gradually move on to more complex solutions.

If you use a voice recorder for important recordings (lectures, interviews, business meetings), check the sound quality in advance, just make a test recording in a quiet room and listen to it with headphones, so you can quickly identify the problem and fix it before the critical moment.

Checking of microphone holes: dust and pollution

The most common, but common, reason for silent recordings is clogged microphone holes, which are usually located on Xiaomi smartphones:

• 📍 In the lower part of the body (near the connector) USB-C)
• 📍 On the upper end panel (near the speaker)
• 📍 Under the camera (on some models, for example, Redmi Note 12 Pro)+)

Dust, pile from your pocket or residues of cosmetics (if the phone was in your bag) can block the sound from accessing the microphone.

1. Take a soft brush (for example, for makeup) or a toothpick with cotton wool.
2. Carefully walk through the holes without pressing hard - so as not to damage the protective net.
3. To remove sticky contaminants, use alcohol wipes (do not drip liquid on the body!).

💡

If the microphone holes are heavily clogged, you can use a can of compressed air (as for cleaning the keyboard).

After cleaning, make a test note. If the sound is clearer, the problem is solved. If not, move on to the next step.

2. dictaphone settings: sensitivity and recording format

Xiaomi's standard Mi Recorder app has hidden settings that affect the volume of the recording, many users are unaware of their existence.

Open the application and go to ⋮ (three-point) → Settings → Record quality. Options are available here:

If your voice recorder doesn’t have these settings, try the side of the app:

• 🎤 Hi-Q MP3 Recorder – allows you to adjust the microphone amplification manually.
• 🎤 Voice Recorder & Audio Editor – has a built-in equalizer for recordings.
• 🎤 ASR Voice Recorder – Optimized for Xiaomi and supports the format FLAC.

3. Microphone Diagnostics: Hardware and Software Tests

If the cleaning and settings didn't work, you need to check the microphone's performance at the hardware level.

Method 1: Testing through the Engineering Menu

1. Open the Phone app and enter the combination: ##4636##.
2. Go to the section Phone Information → Testing menu.
3. Select the Microphone Test and talk to the microphone, and if the bandwidth is unresponsive or the signal level is below 30 percent, it's a hardware problem.

Method 2: Verification through third-party applications

• 🔊 Microphone Test (from Keuwlsoft) – shows the signal level in dB.
• 🔊 Sound Meter – Measures the volume of surrounding sounds.

The critical point is that if the microphone doesn't work in the recorder, or when you call, or when you send messengers, it's a 100% hardware malfunction, and you can't fix it by yourself: you need to disassemble the phone and change the microphone.

4. Application conflict: what prevents recording?

On Xiaomi smartphones (especially those with MIUI shells), some apps can block access to the microphone or reduce its priority.

• 🚫 Battery Optimizers (e.g., Security or Battery Saver) – Restrict background applications.
• 🚫 Messengers (WhatsApp, Telegram) – can “capture” the microphone for voice messages.
• 🚫 Voice chat games (PUBG Mobile, Free Fire – use microphone in the background.

How to check:

1. Close all applications through Recent → Close all.
2. Turn off battery saving for recorder: Settings → Applications → Recorder → Battery → No restrictions.
3. Check the permissions: Settings → Applications → Recorder → Permissions → Microphone (should be allowed).

If you've made the sound better after that, it's one of the conflicting apps that's to blame, and to detect it, turn on the programs one at a time and check the recording.

5. Update firmware and reset settings

Sometimes the problem lies in firmware bugs, especially if you haven't updated MIUI in a long time. The manufacturer regularly releases patches that fix microphone errors.

1. Go to Settings → About the phone → System update.
2. Click Check Updates and install the latest version.
3. After the update, restart the phone.

If the update did not help, try resetting the voice recorder settings:

1. Open the settings → Applications → Recorder.
2. Select Warehouse. → Clear the data.
3. Restart the application and set it up again.

💡

Before you reset the recorder, save the important records -- they'll be deleted! Move them to the cloud or to your computer.

If the problem persists, the latest software method is to completely reset the phone (Settings → Additional → Restore and Reset → Reset) This is a radical solution, but it helps in 80% of software failures.

6. Hardware malfunctions: when to contact the service

If all previous methods have failed, it's probably a hardware problem, and here are the signs that you need to repair.

• ⚠️ The microphone does not work in all applications (dictator, calls, instant messengers).
• ⚠️ Sound distorted: wheezing, crackling, interruptions.
• ⚠️ The phone fell or came into contact with water.
• ⚠️ The problem arose after disassembling the phone or replacing the screen.

The cost of repairing the microphone on Xiaomi in 2026:

Before you bring your phone to the service, check the warranty. If the device is warranty, do not disassemble it yourself - this will void the right to free repair.

💡

Before you visit the service center, back up your data. Sometimes, a full phone reset is required for diagnosis.

Alternative solutions: external microphones and programs

If repairs are not feasible (e.g. on an old phone), you can use external devices to record:

Option 1: USB/Type-C microphones

• 🎙️ BOYA BY-M1 — Budget lavaier microphone with adapter for smartphones.
• 🎙️ Shure MV7 — Professional Podcasting Solutions (requires) OTG-cable).
• 🎙️ Rode VideoMic Me – a compact microphone for video and voice recordings.

Option 2: Wireless headsets

Some of them TWS-Headphones (such as Xiaomi Buds 4 Pro or Redmi Buds 5) have built-in high quality microphones:

1. Put your headphones on Bluetooth.
2. In the recorder, select the sound source: Bluetooth microphone.
3. Start recording – the sound will come from the headset, not from the built-in microphone.

Option 3: Software processing

If the recording is quiet, it can be amplified by:

• 🎛️ Audacity (Free Editor for PC).
• 🎛️ Lexis Audio Editor (mobile app for Android).
• 🎛️ Adobe Audition (Professional Tool).

💡

When amplifying the sound in the editor, do not raise the volume by more than +12 dB – this will add noise and distortion.
