Xiaomi, Redmi and Poco smartphone owners often use built-in tools to dictate lectures, interviews or personal notes, but face the need to refine the resulting file. The standard Dictophone app in the shells of MIUI and the new HyperOS has basic functionality that allows simple trimming, but more complex processing often requires third-party solutions. Understanding how to edit the recording of the recorder becomes critical when you need to remove unnecessary pauses, cut out extraneous sounds or improve speech readability.
The editing process is directly dependent on the version of the operating system and the specific model of your device, as system constraints can vary. In some cases, the embedded editor hides advanced features that are only available through certain actions, while in other situations the only way out is to use specialized software. We will analyze all available methods, from native tools to professional mobile studios, so you can choose the best option.
It is important to consider that the quality of the original audio file is crucial to the ability to process it later. If the recording was conducted in high wind or background noise, standard tools may not cope, and you will need to use noise reduction algorithms. Next, we will look in detail step-by-step algorithms that will help to bring your audio recordings in order.
Basic features of the built-in editor dictaphone
The standard app, which is pre-installed on all smartphones of the brand, provides the minimum necessary functionality for quick editing. Once you open the desired entry in the list, you will see an interface with buttons to control the playback and visualization of the sound wave. It is this wave that allows you to visually determine where the pauses are and where the main speech is, which makes it easier to navigate over long files.
To access editing functions, you need to click three dots in the corner of the screen or select the appropriate item in the menu, and there are options for cropping the beginning and end of the track, as well as splitting the file into parts. However, it is worth noting that the functionality of the built-in editor is often limited to these actions alone, not allowing you to apply effects or change bitrate.
⚠️ Note: If you save changes to the embedded editor, the original file can be overwritten without recovery. Always create a copy of an important record before you start any manipulations.
Users often wonder if it is possible to glue several files inside the app. Unfortunately, Xiaomi’s native interface does not support the linking function, and this will require third-party software. However, for simple tasks, such as removing the introduction or the final part of the conversation, built-in tools are enough.

Use the Favorites feature in the recorder to mark important moments during recording – this will make it easier to edit later.
Step-by-step: how to cut and share audio
The pruning procedure is the most popular feature that allows you to remove excess time at the beginning or end of a record. To perform this operation, open the file, select the edit mode and move the sliders on the timeline, limiting the area that you need to save. Once you set the boundaries, click the confirmation button and the system will suggest that you save the result as a new file or replace the old one.
Separating an audio file is useful when you need to cut the middle or save individual quotes from a long lecture. The algorithm is similar: you set the slider to the desired point and choose the "Separate" function. The file will be divided into two independent tracks that you can work with separately.
☑️ Pre-trimming check
It is important to understand that when a file is split, metadata such as creation date or tags can be reset or duplicated. For professional audio work, this can be a problem requiring manual adjustment of the file properties through the file manager.
| Action. | Place on the menu | The result |
|---|---|---|
| Cutting edges | Editing → Cutting | Start/end removal |
| Separation | Editing → Editing → Separate | Two files from one |
| Conservation | Save button | Fixing changes |
| Cancellation | Back button | Return to the original |
Noise removal and sound quality improvement
One of the main problems with mobile recordings is background noise, which can make speech indistinct. Newer versions of the HyperOS shell and some MIUI updates have a smart noise reduction feature that activates automatically or through microphone settings. If your smartphone supports this feature, the recording quality will improve significantly even during the dictation stage.
If a recording is already made and contains noise, it's almost impossible to remove it with built-in tools, and then artificial intelligence algorithms available in online services or specialized applications come to the rescue, analyzing the frequency spectrum and suppressing sounds that are not related to human speech, such as street hums or static crackling.
Consider that aggressive noise cancellation can lead to a robotic tone of voice, and balance between the cleanness of the background and the naturalness of the sound, and this is especially critical for interviews and podcasts, as the listener will immediately notice the unnatural artifacts of processing.

Third-party applications for advanced editing
When the standard tool is not enough, users turn to third-party software from the Google Play store, the leader in this niche is the Lexis Audio Editor app, which turns a smartphone into a full-fledged sound station, which allows you to work with multiple tracks, apply an equalizer, compressor and various filters.
Another popular option is the MP3 Cutter and Ringtone Maker, which focuses on quick and simple trimming without unnecessary complications. For those who need deep spectrum analysis and the ability to draw an envelope volume, WaveEditor will suit. The choice of the specific application depends on your goals: creating a ringtone or mastering a podcast.
- 🎚️ Lexis Audio Editor – professional tool with support for effects and multilayering.
- ✂️ MP3 Cutter – a simple solution for quick cropping and gluing files.
- 🎙️ Dolby On – an application for recording and automatically improving sound with effects.
- 📊 WaveEditor – a powerful editor with spectrum visualization and support for formats.
Installing third-party software requires attention to the permissions the application requests. To work with audio files, the program needs access to storage, and to record it - to the microphone. Be careful with applications that require excessive access rights, and download the software only from trusted sources.
Working with formats and converting files
Xiaomi smartphones often retain.m4a or.aac recordings by default, which provide good quality with a small file size. However, compatibility with some voice recorders or players may require conversion to a more versatile.mp3 or uncompressed.wav.
Many third-party editors have an inbuilt export feature that allows you to select the desired format and bitrate when saving. If you use the built-in application, you may need to use online converters that work directly in the Chrome browser or MI Browser. This takes longer, but does not require installing extra software.
When converting, it is important not to lower the bitrate too much, otherwise the sound quality will fall, and digital artifacts will appear. The optimal value for speech is 128 kbit / s, and for music or high-quality recordings, 320 kbit / s. The.wav format takes up much more space, but retains the original quality without loss.
⚠️ Attention: Conversion from lossy format (MP3) lossless (WAV) It will not improve the sound quality, but will only increase the file size.
Where are the recordings of the recorder stored and how to find them
Understanding the Android file structure on Xiaomi devices is essential to transfer recordings to a computer or to process them in other programs. By default, all voice recorder files are stored in internal memory in a way that can be hidden from normal viewing in some versions of the system.
To find files, open the Explorer app and go to the folder MIUI, later sound_recorder. This is where all your records are, sorted by date, and if you can't see this folder, turn on the hidden files in the Explorer settings.
/storage/emulated/0/MIUI/sound_recorder/For easy work with files on your computer, you can connect your smartphone over USB in file transfer mode (MTP), which will allow you to copy records to your hard drive and process them in desktop editors such as Audacity or Adobe Audition, which have much more powerful functionality.
💡
The path to records is standard for all Xiaomi models, but in Android 11+ file-access Android/data It can be restricted without special rights.
