Modern smartphones like the Xiaomi Redmi Note 8 Pro have powerful multimedia capabilities, but standard customization settings often limit the user. Device owners often face the need to set a unique melody to a contact or incoming call, but the built-in audio editor may be missing or hidden in the depths of the menu.
There are several effective ways to solve this problem, from using pre-installed system utilities to installing third-party software from Google Play. The choice of a particular method depends on how deep you are willing to dive into the file system settings and whether you need a professional result with smooth attenuation. In this article, we will discuss all the options available in detail so that you can quickly and error-free customize your gadget.
Do not neglect the quality of the source file, as it depends on the final sound. Before you start manipulating, make sure that the track is stored in the device memory or on the device. SD-The best format for ringtones on Android is MP3 or AAC, We're going to go on to the practical methods of editing.
Use of the built-in MIUI dictaphone
Many users do not even realize that the MIUI firmware installed on the Redmi Note 8 Pro already has a basic tool for working with sound. The built-in voice recorder allows you not only to record your voice, but also to perform a simple cropping of already existing tracks, this method is ideal for those who do not want to litter the memory with unnecessary applications.
The process starts with opening the standard Dictophone app. In the upper right corner of the interface, there is a menu where you select Audio Record or go to the list of saved files. If the desired track is not there, it can be imported using the system audio recording function or simply opening the file through the explorer and selecting the Dictaphone as a playback program, then running the record (although this will reduce the quality).
But a more advanced version is built into the standard audio player or ringtone selection menu, and when you select "Your ringtone" in the audio settings, the system can offer a built-in editor, which has the beginning and end sliders available, and the accuracy of the cropping is limited here, but it's enough to highlight the chorus of the song.
- 🎵 Open the "Dictorphone" or "Music" app on your device.
- ✂️ Find the file you want and select the edit or crop option.
- 💾 Save the result as a new file so you don’t lose the original.
💡
Save the cropped file under a new name so that in case of an error you can return to the original version of the track without loss of quality.
It should be borne in mind that the functionality of the built-in tools can vary depending on the version of MIUI. On some updates, the interface may differ, but the logic of the work remains the same. If the standard means of cropping is not possible, the system will offer to download the necessary plugin or application.
Overview of the Best Apps for Cutting Audio
If Xiaomi’s standard functionality isn’t enough, Google Play’s specialized apps will come to your rescue, providing advanced features such as sound wave visualization, fade in/fade out, and support for multiple formats, a choice for those who want to get a professional result.
One of the most popular solutions is the MP3 Cutter and Ringtone Maker application. It is characterized by a simple interface and high speed even on the MediaTek Helio G90T processor installed in the Redmi Note 8 Pro. Another strong player in the market is Lexis Audio Editor, which offers features close to desktop audio editors.
When choosing software, pay attention to the presence of advertising, as free versions often sin obtrusive banners. It is also important to check the permissions that the program requests. To work, it only needs access to media files and storage, requests for access to contacts or location should be alerted.
Installing third-party software gives you complete control over the duration and structure of the ringtone. You can glue multiple pieces, change the tone or playback speed. Lexis Audio Editor, for example, allows you to work with multi-track projects, which is rare for mobile platforms.
Step-by-step trimming instructions in MP3 Cutter
Consider the process of creating a ringtone using the MP3 Cutter app, as it is the most popular among Android smartphone owners. Once you install and run the app, you will see a list of all the audio files available in the device's memory. The interface is intuitive and does not require long learning.
Choose the track you want to edit. You'll open a window with a visual sound wave. You'll use two sliders (beginning and end markers) to highlight the desired snippet. You can use zoom buttons to fine-tune it to push the boundaries to within a millisecond, which is critical to getting into the rhythm of the composition.
☑️ Track trimming algorithm
Once you select the area, press the save button, you will be asked to select format (usually MP3) and quality (bitrate). For ringtones, you should not choose maximum values, 128 or 192 kbit / s is enough to save space. Specify the file name and destination folder, then click Save.
⚠️ Note: When saving a file, make sure you don't overwrite the original. Always make a copy, as the pruning process can be irreversible without the source code.
The finished file will automatically appear in the list of available ringtones in the phone settings. If this does not happen, use the built-in file manager to move the file to the Ringtones or MIUI/sound system folder. This ensures that the system recognizes it as a standard call sound.
Editing through online services
In situations where installing apps is impossible or undesirable, you can use online editors, services like AudioTrimmer or MP3Cut run directly in the Chrome browser or MI Browser, which is convenient because it does not require internal memory with additional software.
The way it works is the same as desktop versions: you upload a file through the cloud, allocate the desired area and download the result. The processing speed depends on your Internet connection. 8 Pro with its fast network support 4G/LTE This process will take place almost instantly.
The main advantage of the online method is cross-platform, you can start editing on your phone and finish on a tablet or computer if your account is synchronized, but keep in mind privacy: don't upload files containing personal or sensitive information to the web.
| Parameter | Annex (MP3 Cutter) | Online service | Built-in dictaphone |
|---|---|---|---|
| Internet is required | No. | Yes. | No. |
| Precision of pruning | Tall. | Medium | Low. |
| Effects | There is. | Limited. | No. |
| Remembrance class | Yes. | No. | No. |
Online tools often have limits on file size (typically up to 50-100 MB) for full-length music tracks, but long podcasts or audiobooks will have to find other solutions, and many services compress audio when converting, which can reduce quality.
Installation of a cropped melody on a call
Once you've successfully trimmed a track, you need to set it to a call. In the MIUI shell, this process has its own peculiarities. Go to Settings and select Sounds and Vibration. Here you'll see sections to adjust the bell sound, notifications and alarm.
Click on "Rington." In the list that opens, at the top, you'll have a source or plus button. The system will suggest you select a file from memory. Find the folder where you saved the cropped track (often a Music or Recordings folder).
What if the system does not see the file?
To set a customized tune to a specific contact, the process is slightly different: Open the Contacts app, select the right person, and click Change. In the editing menu, find the Melody field (or Rington) and specify the previously prepared file. Now you will know who is calling without even looking at the screen.
Remember, the length of the ringtone matters too: a file that is too long can be cut by the system automatically or repeated in cycles at an uncomfortable moment; the optimal duration is 15 to 30 seconds; this is enough time to hear the beginning and respond to the call.
Common mistakes and ways to solve them
During the setup process, users of the Xiaomi Redmi Note 8 Pro may encounter a number of problems. Often, after cropping, a file is played with distortion or crackle. This happens if the bitrate or loss format was chosen when saving. Always check the export settings in the editor application.
Another common problem is that the file is not installed on the call, which may be due to access rights, make sure that the editor application or file manager is given permission to read and write in storage, and in modern versions of Android (10 and above), access to the file system is strictly regulated.
⚠️ Warning: If the sound is played only once after setting the ringtone or is interrupted, check if the Silence or Do Not Disturb mode is on for certain contacts, which may override your settings.
Also worth mentioning is the tag encoding problem, and sometimes the track name is displayed by the cranks, and you can solve this by renaming the file in Latin or using special editing apps. ID3-Metadata purity is important for correct display in the call list.
💡
The quality of the final ringtone depends not only on the source, but also on the correctness of the export settings and the format compatibility with the MIUI system codecs.
In rare cases, you may need to reset the audio settings to factory if the system starts to work incorrectly with audio files, this is done through the audio settings recovery menu, but in 99% of cases the problem is solved by simply converting the file to a standard MP3 with a sampling rate of 44.1 kHz.
