“My favorite music files that I encoded from CDs when I was young are now garbled on modern smartphones!”
"Music Garbled Fix" is an app for those who are grieving.

"Music Garbage Fix" is an app that allows you to automatically correct garbled music files on your smartphone.
Although there are several such apps if you search the store,
It seems that it often does not work on recent Android versions.
This app is characterized by running on Android 12 or later, and is mainly tested on Android 13 environment.

>> How to use
1. Select the folder containing music files
2. Confirm the correction details on the confirmation screen and press the "Execute correction" button.
*Please back up the original file so that you can restore it if anything happens.

>> Compatible extensions
Compatible with mp3 and m4a.

>> Modification details
Converts all full-width tildes in (album name/song name/artist name) to wave dashes.
The conditions under which garbled characters occur are complex, and garbled characters do not always occur even if full-width tildes are included.
Please note that files that are not actually garbled may also be included in the correction target.
In that case, there should be no negative effects.

>>Please
If there is a pattern of garbled characters that cannot be fixed with this app, please provide detailed information.
Please provide enough information to reproduce the issue and we will do our best to help.
