How to change the notification sound of Xiaomi Redmi 9

Owning a Xiaomi Redmi 9 offers a wide range of personalization options, allowing you to turn a standard device into a unique gadget that reflects your style. One of the easiest but most effective settings is to replace a standard monotonous call with a pleasant melody or voice message. This action not only improves aesthetic perception, but also helps you instantly recognize the type of incoming event from the characteristic sound, which is especially useful in noisy environments.

The process of setting up the audio system in the MIUI shell is quite logical, but beginners are often lost in the abundance of menus and hidden options. We will discuss in detail all the available ways to change the audio, from basic system settings to fine-tuning for specific applications. You do not need to install third-party programs or have superuser rights, since all the necessary functionality is already built into the operating system.

Basic setting of system sounds

The most common use case is to replace the standard call for incoming calls and general notifications. First, you need to go to the main settings menu of your device.

Depending on the firmware version and regional setting, this item may be called Sound and Vibration or just Sound, and this is where all the volume sliders and vibration mode switches are concentrated.

When you go to the right section, you'll see a list of categories available: call, notifications, alarm clock, and multimedia. When you click on Phone Call, you'll be taken to the preset melodies gallery, and you can listen to each option just by tapping its name and select the most appropriate one.

If you find the standard set too boring, the system allows you to use your own audio files. To do this, there is often a button at the top of the list of tunes with a plus symbol or a folder icon. mp3-file stored in the device memory or on a memory card.

• 📁 Use the button "+" loading up your own mp3-file.

It's important to note that the changes are instant. You don't have to restart the device or confirm the action with the Save button. However, if you use third-party themes, some system sounds can be replaced by the author's options that are part of the theme.

Set up individual notifications for applications

One of the key features of the MIUI shell is the flexibility to manage notifications for each application installed. This is especially true for Redmi 9, which is often used as the main communication center. You can customize unique audio signals for instant messengers, social networks and email clients.

To change the sound for a particular application, such as Viber or Telegram, you need to go to the Notifications and Status bar section, and then select Application Notifications, and here is a complete list of all programs that have the right to display information on the lock screen.

Use different sounds for work and personal messengers to instantly understand if the message requires urgent attention or can wait until the evening.

The system allows you to assign different sounds to even different types of events within the same application, for example, in message settings, you can split sounds for personal correspondence and notifications from channels or groups, which helps filter information noise and respond only to really important events.

⚠️ Note: Some apps, such as WhatsApp, may have their own internal audio settings that override the system. If the change to the phone menu doesn't work, check the settings inside the app itself.

Remember that too many unique sounds can lead to confusion, and it is recommended that you use no more than 3-4 different tunes for different categories of applications: one for calls, one for urgent messages and one for secondary notifications.

Sound control for two SIM-map

Xiaomi Redmi 9 supports two SIM cards at the same time, which is the standard for modern smartphones, which creates the need to separate the audio signals so that the user can understand which line the incoming call is coming to without looking at the screen.

In the Sound and Vibration section, you'll find individual items for the first and second SIM cards, usually designated as SIM 1 and SIM 2, or carrier names if they're automatically identified, and by clicking on each of these, you can assign a unique tune.

It's recommended to choose contrasting tunes, for example, for a working SIM card, you can set a strict, short signal, and for a personal one, a longer and more melodic composition, which will allow your brain to automatically classify the call before you even pull the phone out of your pocket.

In addition, in the same menu, you can configure notification sounds separately for each SIM card, although most often users leave them the same or tied to the main number. MIUI It allows you to adapt the behavior of the device for any, even the most complex use cases.

If you rarely use a second SIM card, you can turn off the sound of incoming calls for it completely, leaving only vibration, which will help you not be distracted by secondary calls during working hours, preserving the ability to see missed calls later.

Use of your own audio files

The standard set of tunes that comes with the Xiaomi Redmi 9 may seem limited. Fortunately, the Android system makes it easy to use any audio files stored in the device's memory as system sounds.This opens up access to thousands of tracks, movie soundtracks or voice recordings.

First, make sure that the desired audiophile is in the phone's memory. It is best to place such files in the Music folder or create a separate Ringtones folder at the root of internal memory for easy navigation. The file format should be compatible, most often MP3, M4A or OGG.

The installation process is simple: go to the melody selection menu, click the add button (usually a plus in the corner), and in the file manager that opens, find your track. The system automatically scans the media files and offers them in the list of available ones.

The Way to the Folder: Internal Memory → Music → My Ringtones

For phone calls, the optimal duration is 20-30 seconds; for too long songs, the system will cut off or sound unnatural if the call is reset at the beginning; for notifications, it is better to choose short fragments of 2-5 seconds.

• 🎵 Download or create an audiophile in format MP3 length.
• 📂 Move the file to Ringtones or Music for quick access.
• ⚙️ In the audio selection menu, press "+" Find your file in the list.
• ✂️ Use the built-in editor (if any) or third-party apps to trim the track.

If you want to install audio from a video, you first need to convert the video file to an audio format, which can be done using online converters or special ripper applications available from the Google Play store.

Fine tuning of volume and vibration

Replacing the melody is only half the battle. It's equally important to adjust the volume levels correctly so that the sound is heard in a noisy place, but not stunned in silence. The Redmi 9 has a powerful speaker that requires careful calibration.

The Sound and Vibration menu has an expanded volume control, and if you click on the gear icon next to the slider or select Additional Sound Settings, you'll see the separation of multiple channels: media, bells, alarms, and notifications, each of which can be set independently.

The most important thing to consider is the alarm clock volume, which is often maximized by users, but in the morning, it can be unpleasant to hear a loud sound, and it is recommended that you set an average that is sufficient to wake up, but not stressful.

Vibration is an important tactile component of notifications, and you can adjust the vibration force and its patterns in the same menu, and for some types of notifications, Vibration on Call is available, which allows the phone to vibrate in the rhythm of the melody, creating a unique effect.

⚠️ Attention: Constant operation of the vibrator at maximum power can consume battery power faster. If energy saving is a priority, use audible signals instead of strong vibration.

Modern versions of MIUI also feature adaptive volume, which analyzes ambient noise and automatically raises the volume of the call in noisy places, an option that can be found in advanced audio settings and enabled for greater comfort.

Table of parameters of sound profiles

For user convenience, the system offers several ready-made profiles that change the behavior of the sound system depending on the situation, and understanding the differences between them will help you navigate the settings faster.

You can switch between profiles not only through settings, but also through the control panel. Swipe down from the top edge of the screen to open the notification curtain, and find the speaker or profile icon. Long tapping on this icon often opens the direct selection menu.
