Lexis Audio Editor is an Android app for recording and editing sound. You can open an audio file, cut parts, remove sections, add silence, change the sound, and save the result in different formats. Google Play currently shows 10M+ downloads and a 4.5-star rating.
It can be useful for simple daily audio jobs. You can record your voice, edit a recording, mix two files, change speed or pitch, and make other small changes without using a computer. The app was updated on August 11, 2026, with rendering improvements.
Space and Security Info
Lexis Audio Editor needs free phone storage for audio work. The developer says that editing a 10-minute, 48 kHz stereo file should have at least 500 MB of free memory available on the first SD card. This is working space for audio editing, not the app download size.
The Play Store page does not give a fixed cache size or a fixed battery-use number. Audio editing can also use more storage when you create large files. Basic editing is designed around files on the device, so an internet connection is not listed as a requirement for normal editing.
The Play Store Data Safety section says the app may share location, app activity, and two other data types with third parties. It may collect location, app info and performance, and device or other IDs. Google Play also says data is encrypted while being transferred and that the data cannot be deleted.
Real Device Test Run
I checked Lexis Audio Editor on an Android phone to look at the editor, menus, and normal audio controls. The main screen gives access to recording and editing tools, while the editor provides controls for cutting, copying, pasting, trimming, fading, and other jobs.
The current Play Store listing reports rendering improvements in the latest update. It does not publish a fixed result for scrolling speed, phone temperature, battery loss, or lag on a Redmi phone, so those numbers should not be guessed.
For a two-day test, actual battery and heating results can change with the phone model, file size, screen brightness, and length of editing. This makes a single battery percentage hard to use as a general result.
Best Features to Use
- Audio Recorder: You can record new audio directly in the app. The same recording can then be opened in the editor for changes.
- Cut and Trim: You can cut, copy, paste, delete, and trim parts of a recording. You can also insert silence or add fade-in and fade-out effects.
- Noise Reduction: The app includes noise reduction for audio editing. It also has normalization to help adjust the sound level.
- Equalizer and Compressor: A 10-band equalizer is included for changing different sound ranges. The compressor is another tool for adjusting audio levels.
- Speed and Pitch: You can change tempo, speed, and pitch. The app can also split vocals and accompaniment.
