Xiaomi Redmi 9 smartphone based on MIUI offers flexible settings of soundtrack, but not all users know how to use them effectively. Standard ringtones are quickly boring, and attempts to put your favorite song often fail due to the features of the firmware. In this article, we will analyze all possible ways to change the ringtone, from basic settings to using third-party applications, and also reveal the hidden limitations of MIUI 12-14 when working with custom tunes.
The feature of Redmi 9 (codenamed lancelot) is that the system by default blocks the selection of tracks lasting more than 30 seconds and limits supported formats. We will show you how to circumvent these restrictions without root rights, and also share life hacks on optimizing sound for different scenarios (work / home / night mode).
Preparation: what files are suitable for the ringtone
Before you change the ringtone, it is important to understand which audio files are guaranteed to work on the Redmi 9. MIUI supports the following formats:
- 🎵 MP3 — The most versatile option (bitrate 128-320 kbps)
- 🎵 M4A (AAC) — better compression with the same quality
- 🎵 WAV — without loss of quality, but takes up a lot of space
- 🚫 FLAC, OGG, WMA — not supported by default
Key requirements for the file:
- ⏱️ Duration: up to 30 seconds (otherwise it will be cut automatically)
- 📁 Placement: Ringtones or Notifications folder at the root of internal memory
- 🔊 Loudness: normalize the sound to -16 LUFS (Use Audacity or online services)
💡
If your track is longer than 30 seconds, cut it in the MP3 Cutter app (available in the Play Market) and choose the most dynamic snippet so the call can be heard better in a noisy environment.
For testing, you can download Xiaomi's official ringtones, which are optimized for MIUI and do not cause errors. If you want to use your music, convert it to MP3 with a bitrate of 192 kbps via Online-Convert or Format Factory.
Method 1: Selecting a standard melody from system settings
The easiest method is to use built-in ringtones. Here's a step-by-step instruction:
- Open the Settings app (cog icon).
- Go to the section Sound and vibration.
- Slap on the call melody item.
- In the list, select one of the categories: 📱 MIUI — Xiaomi signature tunes 🎶 Local – Tracks you have uploaded 🔕 No sound – vibration without ringtones
OK.
Note that MIUI 14 has introduced Adaptive Sounds, which automatically adjusts the ringtone volume based on the noise level in the room. To activate it, go to Settings → Special Features → Adaptive Sound.

Method 2: Install custom tunes from the gallery
If the standard ringtones don't work, you can upload your audio file.
- Place the prepared file (see Preparation) in the Internal Storage → Ringtones folder. Create it manually if it is not available.
- Open Settings → Sound and vibration → Call melody.
- Select the Locals tab.
- Slip on the right track and confirm the choice.
If your file does not appear in the list, follow the following steps:
- 🔄 Reboot the phone — MIUI scans media files at start.
- 📂 Check that the file is in the Ringtones folder, not in Music or Downloads.
- 🔍 Use a file manager (such as Mi File Explorer) to update your media index: Open the file folder → press three dots → Scan.
Why doesn't MIUI see my tune?
The Redmi 9 is a good idea if you use two. SIM-You can customize the ringtone melody for each card, and you can do that by tapping the ringtone icon on the ringtone selection menu. SIM-maps in the upper right corner and select the desired line.
Method 3: Using Third-Party Applications
If the built-in MIUI tools seem limited, install a dedicated application.
| Annex | Advantages | Deficiencies | Reference |
|---|---|---|---|
| Zedge | Large library of ringtones and notifications, weekly updates | Advertising in the free version requires access to storage | Play Market |
| Ringtone Maker | Track trimming, volume normalization, support for all formats | The interface is overloaded, sometimes laying on weak devices | Play Market |
| MP3 Cutter | Simple editor, export directly to Ringtones folder | Restriction on the length of the track in the free version (20 seconds) | Play Market |
Instructions for setting up through Zedge:
- Install and open the application.
- In the search bar, type a query (for example, “electronic tune”).
- Choose your favorite ringtone and click Download.
- After downloading, tap Set as a ringtone.
- Confirm the choice in the system menu MIUI.

Warning: Some apps (like Ringtone Maker) ask for permission to change system settings. Do not provide it if you are not sure about the security of the program - this can lead to unstable phone operation or data leakage.
Additional settings: vibration, volume and profiles
The ringing melody is just part of the sound experience, and Redmi 9 can fine-tune the associated settings.
- 📳 Vibration when calling: Open Settings → Sound and vibration → Vibration when calling. Select a pattern from the suggested ones or create yours through Vibration settings.
- 🔊 Volume: Use physical volume buttons during the call to adjust. Activate Do Not Disturb in Settings → Notifications for automatic volume reduction at night.
- 🔄 Sound profiles: MIUI Supports Work, Home and Outdoor modes. Configure them to Settings → Sound and vibration → Sound profiles.
For advanced users: If you need to turn off missed call notifications on a locked screen, go to Settings → Screen Lock → Lock screen notifications and turn off Calls option.
💡
On the Redmi 9 with MIUI 13+, the Smart Sound feature is available – the phone automatically switches to vibration in your pocket or bag. Activates in Settings → Additional → Smart Features.
Problem Solving: Why the Call Melody Doesn't Change
Sometimes users find that changes don't apply, and let's look at the typical reasons and ways to address them:
| Problem. | Possible cause | Decision |
|---|---|---|
| The melody is reset after rebooting | Failure in the app's cache Settings | Clear the cache: Settings → Applications → App management → Settings → Storage → Clear the cache |
| The file does not appear in the list | Incorrect placement or format | Check the Ringtones folder and convert the file to MP3 |
| The sound is interrupted or distorted | Too high bitrate or corrupted file | Use files with bitrates of 192–256 kbps |
| The melody works, but very quietly. | Volume limitation in MIUI | Activate the Sound Amplifier in the Engineering Menu (#36446337##) |
If none of the methods helped, reset the sound settings:
- Go to Settings → System and device → Resetting.
- Select Resetting Sound Settings.
- Confirm the action and restart the phone.

Tips for Choosing the Perfect Call Melody
A properly chosen ringtone not only highlights your phone, but also performs a practical function.
- 🎯 Recognition: The first 2-3 seconds should be recognizable (avoid long intros).
- 🔊 Clearness of sound: Test the melody in noisy environments (e.g., in the subway).
- ⚡ Energy efficiency: Simple tunes (like Nokia Tune) consume less charge than complex compositions.
- 😴 Social Acceptability: Avoid harsh or annoying sounds in public.
For Redmi 9, we recommend the following types of ringtones:
- 📟 Classic: Short signals (e.g. Old Phone Ring).
- 🎹 Minimalist: piano or synthesizer melodies.
- 🌊 Natural sounds: waves, birds (but not too quiet).
- 🤖 Voice: Movie or game phrases (e.g., "Incoming transmission" from Mass Effect).
Remember: MIUI limits the maximum volume to protect the speakers. If you need to turn up the volume above the limit, use the Volume Booster app (but risk distortion of the sound).
