How to Cut a Melody to a Call for Xiaomi Redmi 9

Personalization of a smartphone is the first step to creating a comfortable digital environment, and for owners of Xiaomi Redmi 9, this process begins with choosing a unique ringtone. Standard tunes preset by the manufacturer often seem boring or too intrusive, so many users tend to install a favorite track from their music library. However, simply copying a file is not enough: for perfect sound, you need to accurately highlight the desired piece of the composition, removing unnecessary introductions or quiet endings.

With Android, which runs the MIUI shell, editing audio files can seem complicated at first. In fact, there are many ways to do this, from using built-in gallery features to installing specialized apps from Google Play. In this article, we’ll take a look at all the methods available to help you create the perfect call that fits your style and preferences.

The quality of the cropping directly affects the perception of the incoming call, so it is important to use tools that ensure smooth attenuation of sound and accuracy to the millisecond. We will look at not only the technical aspects of the cropping, but also the nuances of installing the finished file as a system call or individual signal for a particular contact. Let's dive into the world of audio settings of your Redmi 9 and turn a regular track into a personalized signal.

Preparation of audio file and choice of format

Before you start cutting it, you need to make sure that the source file is compatible with your device’s operating system. Xiaomi smartphones work perfectly with MP3, WAV and M4A formats, but for system ringtones, MP3 remains the most stable and recommended format. If your music is stored in lossless formats like FLAC or FLAC, it is better to convert them pre-convert to avoid playback problems or increased battery consumption during decoding.

It's also important to pay attention to the bitrate of the track. The call doesn't require studio quality, so files with a bitrate of 128 kbit/s or 192 kbit/s are the best choice. They take up the minimum amount of storage in the device and are quickly loaded by the processor at the time of incoming call. High bitrates, such as 320 kbit/s, can be redundant for smartphone speakers and waste internal storage.

⚠️ Note: Do not use files with DRM-The security (digital access rights) downloaded from subscription streaming services, which cannot be installed on a call without violating the license agreement, and the system MIUI Just ignore them when choosing the settings.

The location of the file in the memory of the device also plays a role. To make the system find audio faster, it is recommended to store the source and ready-made ringtones in the Music folder or create a separate Ringtones directory at the root of internal memory, which will not only simplify the search, but also allow you to automatically synchronize new tunes with the system list of available sounds after rebooting.

💡

For best compatibility, save the ringtones to the folder. /MIUI/sound_all/ Or create your Ringtones folder at the root of your internal memory so that the system can see it right away.

Pruning through built-in MIUI tools

Redmi 9 owners are lucky because the MIUI shell often includes basic audio editing functions directly in the standard Music or Sound Manager app, which is the fastest way to do so without needing to install additional software. To take advantage of this method, open the track you want, click on the menu (three dots), and select the "Install on the Call" option, where there is often a built-in editor to select the time slot.

The editor interface allows you to visually highlight the waveform area, shifting the boundaries of the start and end of playback. You can listen to the selected snippet several times to make sure that the trimming is done cleanly, without sharp cliffs. The accuracy of the setting in the standard Xiaomi editor is usually about 0.1 seconds, which is quite enough for most popular tracks.

• 🎵 Open the standard Music app on your Redmi 9.
• ✂️ Select a track and find the “Edit” or “Install as a ringtone” function».
• ⏱️ Move the sliders to highlight the desired fragment lasting up to 30-40 seconds.
• 💾 Save the result as a new file without overwriting the original.

However, it is worth noting that the functionality of the built-in editor can be limited depending on the firmware version (Global, EU or China), if you do not find such an option, this means that it has been cut out in your regional build, and you will have to resort to third-party solutions that offer more flexible settings.

Use of third-party editorial applications

If standard features aren’t enough, specialized apps from the Google Play store come to the rescue, with MP3 Cutter and Ringtone Maker, Ringdroid and Lexis Audio Editor leading the niche, providing advanced tools to work with sound, allowing not only cropping the track, but also applying fade effects (Fade In/Fade Out), changing the volume and even applying effects.

The process of working in such applications is usually intuitive: after downloading a file, you see a detailed sound wave. With your fingers you can scale the area for more accurate trimming, which is critical if you want to get exactly to the beginning of the chorus or remove the vocalist's breath before a phrase. Many applications also allow you to save several versions of the track for different contacts or modes (meeting, home, work).

The Lexis Audio Editor app, which is similar to desktop audio editors, not only cuts but also normalizes the volume so that your call is heard enough even in a noisy place, but does not stun in silence, making it a great choice for users who want maximum control over the sound of their Redmi 9.

Step-by-step instructions for creating a ringtone

When the audio is loaded and displayed as a wave, use the zoom function (usually available via double tap or magnifier) to look at the structure of the sound in detail, which will help you pinpoint the beginning and end of the desired phrase.

Select the area you want to leave using the beginning and end sliders. Be sure to play the selected snippet several times. If the sound stops abruptly, find the Fade In and Fade Out effects in the menu. Set the attenuation time to be about 0.5-1 seconds for the natural end of the call.

In the final step, click the Save button. In the window that appears, enter the file name and make sure the format is set as MP3. Some applications will immediately suggest installing the file on a call, contact or notification — you can use this feature or do it manually through the phone's later settings.

⚠️ Note: When saving a file, make sure that the name does not contain special characters such as /, \,:, *,?, ", <, > or |. Using these symbols can cause the Android system to not be able to read the file correctly or it will not appear in the list of ringtones.
