How to Cut a Song on Xiaomi Redmi 9: From Standard Tools to Professional Apps

Cutting audio files on Xiaomi Redmi 9 is a challenge that music fans and regular users face when they want to create a unique call or cut a favorite snippet from a song. A MIUI-based smartphone offers several built-in audio editing methods, but their functionality is often limited. In this article, we will examine all available methods — from basic tools to advanced applications — and also reveal the nuances of working with.mp3,.m4a and.wav formats.

Feature of Redmi 9 (model M2003J15SC/M2004J19C) The processor is called MediaTek Helio. G80 It doesn't always handle heavy audio editors correctly, so we've only selected solutions that are guaranteed to work without lags, and you'll also learn how to avoid loss of quality when trimming and which formats are best used for ringtones.

Method 1: Built-in MIUI Editor (without installing applications)

The fastest but most limited method is to use the standard music app (com.miui.player), which is pre-installed on all Xiaomi smartphones and supports basic track trimming. Importantly, the feature is only available for.mp3 and.m4a files.

How to cut a song:

• 📱 Open the Music app** and find the track you need to edit.
• ✂️ Click on three dots next to the song title → Choose to Cut.
• 🎚️ Drag sliders on the timeline to highlight the desired fragment (maximum accuracy - up to 1 second).
• 💾 Click Save - the file will appear in the folder MIUI/Music/Cuts/.

⚠️ Note: Built-in editor MIUI does not store metadata (artist's name, album cover) If it is critical, use third-party apps.

Advantages of the method:

• ⚡ No need to install additional programs.
• 🔒 It's offline.
• 📱 Optimized for Redmi 9 (no risk of processor overheating).

Disadvantages:

• 🚫 No possibility to add effects (attenuation, volume increase).
• 🔊 Only the beginning and end of the track (you can’t cut the middle).
• 📁 Save files only in format.mp3 bitrate 192 kbps.

Method 2: Rington application (to create ringtone ringtone)

If the goal is to make a ringtone out of a song, it’s more convenient to use the Ringtone app (com.android.soundrecorder).It’s hidden in the Settings menu → Sound → Call Melody → Local ringtone, but it allows you to more accurately customize the beginning and end of the snippet.

Step-by-step:

1. Open the settings → Sound → The ringing melody.
2. Select Local Ringtones → Add.
3. Specify the song from the device memory (supported formats.mp3,.wav,.ogg).
4. Drag the sliders for trimming (maximum ringtone length - 30 seconds).
5. Save the file – it will automatically appear in the list of available tunes.

⚠️ Note: If the ringtone sounds distorted after trimming, check the bitrate of the original file.Redmi 9 does not handle tracks with a bitrate above 320 kbps - it is better to convert them in advance.

💡

To make the ringtone sound louder, increase the volume of the original file in any audio editor (for example, in MP3Louder).

Method 3: Stoornie (Free Editor with Effects)

For users who need advanced features (overlay, mixing, tempo change), Stoornie is a good app. It is free, advertising-free and optimized for MediaTek Helio G80.

How to cut a song in Stoornie:

• 🎵 Import a track through a button + main-menu.
• ✂️ Press Edit. → Trim and select the desired fragment (accuracy up to 0.1 seconds).

Advantages:

• 🎧 Support VST-Plugins (for advanced users).
• 🔄 Possibility of cancellation of actions (editing history).
• 📤 Exports to the cloud (Google Drive, Dropbox).

• 🎛️ 10-band equalizer.
• 🔊 Removing noise and clipping.
• 📊 Visualization of the frequency spectrum.
• 🔄 Batch processing (packet trimming of several files).

Instructions for pruning:

1. Import the file through File → Open.
2. Select the fragment with a mouse or specify time stamps manually (for example, 00:45-01:30).
3. Click Edit → Trim/Crop.
4. Apply effects when needed (e.g. Noise Reduction for old records).
5. Export to.wav (no loss) or.mp3 (with bitrate setting).

Frequent Mistakes and How to Avoid Them

When you trim audio on Redmi 9, you're going to have a problem with the typical ones.

• 🔇 Distorted sound after cropping: Reason: too high bitrate of the original file or compression when saving. Solution: convert the track to 192-256 kbps before editing.
• ⏳ Long file processing: Reason: MediaTek Helio G80 Solution: Use lightweight applications (like Stoornie) or crop files on a PC.
• 📁 File not saved: Reason: lack of memory space or no write rights. Solution: clear the cache or give the app permission to access the storage in Settings → Annexes → Permits.
