How to edit a recording of a Xiaomi voice recorder: the complete guide

Xiaomi smartphones have long proven themselves as powerful multimedia devices that can not only play but also record sound. The built-in Mi Recorder app offers users advanced functionality that is often underestimated. Many device owners do not even suspect that standard software allows not only recording sound, but also conduct basic and sometimes advanced post-processing of files.

The need to change the audio recording can come suddenly: remove the extra pause at the beginning of the interview, rename the lecture file for easy search, or simply cut a funny moment from a conversation with friends. Fortunately, you don't have to download third-party apps or connect your phone to your computer to do this. The built-in tools of the MIUI and HyperOS system cope with these tasks quite efficiently.

In this article, we will take a look at the entire audio file process, where to look for saved records, how to use the built-in editor to trim and rename, and the nuances of format conversion, and understanding these processes will help you keep the record archive in perfect order.

Search and management of the list of records

Before you start editing, you need to find the right file in the memory of the device. The standard application of the voice recorder on Xiaomi has a fairly simple and intuitive interface, but navigation on it has its own peculiarities. All saved files are displayed as a list with an indication of the date, time and duration of the recording.

To access the library, run the Recorder app and look at the top of the screen, and there are usually tabs or switching icons between modes (e.g., "Audio," "Interview," "Conference"). If you don't see the record you want, check if the list is filtered by date or type.

The files in the list are managed by long-term pressing, which opens a context menu that allows you to perform bulk operations, and you can select multiple files at once to delete or move, saving time when cleaning up the memory.

Key list management features include sorting by name or date, and keyword search if transcription is enabled.

⚠️ Note: When you delete a record with a long press and the basket button, the file may not get into the standard gallery or file manager basket, but will be permanently deleted. Always check the contents before cleaning.

Basic editing: cropping and cropping silence

One of the most popular features is audio clipping, and Xiaomi’s built-in editor makes it easy to cut off the extra snippets at the beginning or end of a recording, and remove the pauses in the middle, especially for interviews where the interviewer is silent for a long time before answering.

To start editing, open a specific entry and find the Edit button (usually looks like a pencil or sliders). The editor's interface is a visual wave diagram of sound, where the peaks correspond to loud areas and straight lines correspond to silence.

The pruning process is as follows:

• 🎚️ Move the left and right sliders on the timeline to highlight the area you want to save.
• ✂️ Press the Trim button to remove anything outside the dedicated area.
• 💾 Save the result as a new file so you don’t overwrite the original if you need it in the future.

Some versions of MIUI firmware also offer automatic silence removal, which analyzes the recording and suggests cutting out areas where the sound level is below a certain threshold, which greatly speeds up the processing of long lectures.

Rename and organization of files

By default, the system names the records in the format of "Record GYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY

You can change the title right in the recording viewing interface. Click on the current title or three dots in the corner of the screen ("More") and select "Rename." In the window that opens, enter an understandable title, such as "Lecture Physics Theme1".

Using clear file names makes it easier to search through Android’s built-in search, so you can use keywords in the title to quickly find entries by content, which is especially useful for students and journalists.

In addition, some versions of the recorder have a feature for adding tags or categories, so you can group the records into folders: "Work", "Study", "Ideas" and this creates an additional logical structure on top of the file system.

Format conversion and export

The standard recording format in Xiaomi recorders is often M4A or AAC, which provide good quality at a small size.However, MP3 or WAV may be required to be compatible with some older players or recorders.

The built-in converter allows you to change the file format without loss of quality (within reasonable limits). To do this, select the option "Save as" or "Export" in the editing menu, where you will be asked to select the target format.

The table below compares the main formats supported by the system:

When exporting a file, it is important to consider where you are saving it. You can send the record directly through instant messengers, save it to the Mi Cloud or Google Drive cloud, or simply copy it to another folder of internal storage.

💡

When converting to MP3, choose a bitrate of at least 128 kbps for speech and 192-320 kbps for music to keep the legibility and timbre of your voice.

Working with transcription and text

Modern versions of MIUI are speech-recognition, and the voice recorder can automatically translate voice into text, creating a text copy of the recording, which is incredibly convenient for taking notes of meetings or interviews.

Text transcription is displayed in sync with audio, and by clicking on a line of text, you can (go) to the corresponding moment in the recording, which allows you to quickly find the right quote without listening to hours of audio.

However, it is worth noting that the quality of Russian language recognition can vary depending on the speaker’s diction and the presence of background noise.

You can edit the recognized text right in the app, fixing errors and adding formatting, and then you can copy it and paste it into notes or send it to colleagues.

⚠️ Attention: The transcription function requires an internet connection to process data on the server. Make sure you have a stable Wi-Fi connection or mobile traffic to avoid interruption of the process.
