Changing the standard tune to a personalized track is the first step to making use of the Xiaomi Redmi smartphone 9T It's really comfortable. Many users have difficulty trying to install downloads. MP3-file as a ringtone due to the shell features MIUI. Unlike pure Android, here the process has its own nuances, which, however, are easy to get around, knowing the correct algorithm of actions.
In this article, we’ll look at some proven ways to replace system sound, learn how to use the built-in Themes app, standard explorer, and even third-party utilities if standard methods don’t work. It’s important to understand that the folder structure in new firmware versions may differ, so we’ll look at current ways for the Redmi 9T model.
Before you start setting up, make sure that the desired audio file is already loaded into the device memory. For the best sound quality, it is recommended to choose tracks with a bit rate of at least 128 kbit / s, although modern codecs are great with lighter formats. File preparation is a key step, without which further actions do not make sense.
Preparation of audio file and format check
The first thing you need to make sure your music is in the right place and format.The Android system on which MIUI is based works best with MP3, WAV or OGG formats. If you downloaded a track from a messenger, it can lie in the Downloads folder or inside the directory of a particular application, such as Telegram or WhatsApp.
For easy file management, it’s best to move music to the root folder or create a separate Ringtones directory, which not only makes it easier to find, but also prevents accidental deletion of the track when clearing the messenger cache. Some users mistakenly believe that the file should lie strictly in the system folder, but for Redmi 9T this is not a prerequisite.
Note the length of the track. Too long songs can be cut by the system or not displayed correctly in the selection list. The optimal ringtone duration is 15 to 30 seconds. If the file is too long, it should be pre-edited in any audio editor.
⚠️ Note: Do not use files with DRM-protection (e.g. purchased in older versions of iTunes or taken from paid subscriptions with a restriction) such tracks will not be played as a system call.
The format check is done through the file properties, so if the extension is unknown to the system, the phone will suggest you select an application to open, but will not allow you to install it on the call, in which case the file must be converted.
Method of installation through the application "Themes"
The most common and officially supported way to install a tune on the Xiaomi Redmi 9T is to use the Themes system app, which requires no connection to a computer and works directly from the smartphone interface, and is ideal for those who want to quickly assign a track to a contact or an entire phone book.
To start, open the Themes app. In the lower right corner, click on the profile icon to go to your personal account. Here we are interested in the "Sounds" or "My Sounds" section, which is often hidden in the profile settings menu.
The following sequence of actions should be performed:
- 🎵 Click the “Import” or “Add” button at the top of the screen.
- 📂 The system will prompt you to select the source: select Files or File Manager».
- 🎶 Find your prepared audio file in the list and click on it to import.
- ✅ After downloading the track will appear in the list available, click "Apply».
Once the import is successful, the system will automatically redirect you to the audio type selection menu, so you can set the track as the main call, the notification sound, the alarm clock, or assign it to a specific contact, which ensures that the file is copied to a secure system area, from where it will not disappear.
Importantly, the Themes app may require a network connection to initially synchronize the sound library. If the import does not start, check the Internet connection. Also, in some regions, the Themes app may be limited, then you should use an alternative method through the explorer.
Configuring through a standard conductor
If the Themes app method doesn’t work for some reason or seems inconvenient to you, you can use the classic approach through File Manager, which is more manual, but gives you full control over your Redmi 9T file system.
Open the Explorer app (yellow folder) Go to the section where your music is stored (usually Downloads or Music) and find the file you want, click on it and hold your finger until the action menu appears.
In the menu that appears, select the option “More” (three dots) and find “Install on a call.” If this option is not available in quick access, try clicking “Copy” or “Move”.
☑️ Checklist of installation through the conductor
When you select Move, the system will suggest you specify the target folder. You need to go to the internal memory and find the MIUI -> sound -> ringtone folder. This is where the system scans user ringtones. Once the file is moved to this directory, it will automatically appear in the list of available tunes in the settings.
This is especially useful if you want to organize your sound library manually, so you can create subfolders or sort files by name, but be careful when removing files from system folders so that the sound engine doesn't disrupt the work.
What if you can't see the MIUI folder?
Use of third-party applications for ringtones
When standard MIUI tools fail or the interface seems overloaded, specialized applications from the Google Play Store come to the rescue, taking over the dirty work of converting and installing files, providing convenient access to the soundbase.
One of the most popular solutions is the Zedge or Ringtone Maker application. These programs allow you not only to download ready-made tracks, but also to edit your own: cut out the desired fragment, add damping effects (fade-in/fade-out) and change volume.
Advantages of using third-party software:
- ✂️ Built-in audio editor for accurate track trimming.
- 🌐 A huge online library of free sounds.
- ⚙️ Automatic installation without manual file copying.
- 📱 Support for formats that Xiaomi’s standard player may not see.
When you first run it, it will ask permission to access files and microphones (to record sounds), and you don't have to worry, it's necessary for the editing functions to work properly. Once you install the application, it becomes a simple process: select a track, edit and press the "Install" button.
⚠️ Attention: Be careful when installing free apps from the store. Often they contain intrusive advertising or try to install additional software. Carefully read the installation screens and uncheck the extra checkmarks.
Using third-party software is especially relevant for older models or when using custom firmware, where standard features can be cut down.For the Redmi 9T, it's a great backup option.
Customization of individual sounds for contacts
One of the most useful features of a smartphone is the ability to assign a unique tune to a particular subscriber, which allows you to know who is calling you without taking your phone out of your pocket. On the Xiaomi Redmi 9T, this is done through a standard phone book.
Open the Contacts or Phone app, find the right subscriber in the list, and go to their profile page, and at the bottom or in the menu (three dots) should be the Sound or Melody option.
Clicking on this item will show you a complete list of available ringtones, including those you installed earlier through the Themes app or Explorer. Select a track and confirm the action. Now, when that person calls, the selected song will play.
If you don't see this option in your contact profile, try clicking on the Change button (pencil icon). Sometimes the audio settings are hidden inside the contact card edit mode. Also make sure that the contact is stored in your phone's memory or Google account, not on your phone. SIM-map, because SIM-The cards have limited data storage functionality.
| Type of sound | Where you're tuning in. | Features |
|---|---|---|
| Incoming challenge | Settings → Sound and vibration | Volume is regulated by side buttons |
| Notifications (SMS, messengers) | Settings → Sound and vibration → Additional | You can specify separately for each application |
| Alarm clock | The “Clock” app → The alarm clock settings | Requires a file in memory, streaming does not work |
| Contact | Contact card in the phone book | Priority over the overall ringtone |
And this detail allows you to create a truly personalized sound environment, and you can see if you're getting an important message from your work or if you're getting a call from a loved one.
Solving and eliminating errors
Despite the simplicity of the procedure, users sometimes encounter problems, such as a track may not appear on the list, or the sound may be too quiet, often because of confusion between the volume of the media and the volume of the call.
On the Redmi. 9T, And as with many smartphones today, these channels are separated, so make sure that when you set up the ringtone, you check the volume of the call, not the music. → Sound and vibration.
Another common problem is that the file is not selected. This can occur if the file is corrupted, has an unsupported codec (for example, high-resolution FLAC is sometimes ignored by the call system), or is in a secure folder. Try converting the file to a standard MP3 128kbps.
💡
If the sound is interrupted or wheezing, try to reduce the bitrate of the file. Too high quality (320 kbps or higher) may not have time to buffer at the time of incoming call, especially if the processor is busy with other tasks.
It's also worth checking Do Not Disturb mode. If it's activated, the call can go without sound, even if the melody is set correctly, and you can add exceptions to your favorite contacts in this mode settings.
💡
MIUI requires that the audio file be fully downloaded and available offline to be installed on the call. Streaming tracks without caching will not be installed.
