Software that can losslessly cut music files on Windows PC Although I missed notes on how to use LosslessCut , it is possible to losslessly cut files (converted from .aac to .m4a) generated by Raziko I found the Android application Audio MP3 Editor so I will keep it in my memo.

You can now save time to start up your computer to trim files recorded on smartphones.

Audio MP3 Editor

I tried more than 10 types of cropping tools that are compatible with .m4a trimming out of the cropping tools uploaded on Google Play and it settled in the Audio MP3 Editor.

Audio MP3 Editor reads files quickly, there is no re-encoding process so trimming will end in a moment.

Let's give up as it is a feature of free software that actively displays a dialogue asking for an upgrade or a request for high evaluation.

Recommended setting change

* Verified with Android 7.1.1

Since the Audio MP3 Editor seems to require more authority than necessary, some permissions are turned off, but for now it does not interfere with the operation.

Customization item
Data usage	Background data	OFF
Authority	Contact, Phone	OFF

When changing permissions the following dialog is displayed, so tap "Do not allow".

This application is intended for previous versions of Android. If you do not approve permissions, it may not work as intended.
