**Introduction**

This software performs advanced MP3 operations that would be extremely time-consuming without it. Powered by BASS and FFMPEG, it offers both single-file and batch processing features.

For individual MP3 files, it can:
Run detailed diagnostics
Play only the left, right, or both audio channels
Repair stereo MP3s with only one audible channel by converting them to mono (ensuring playback on both speakers)

In batch mode — with no limits on file count or size — it can:
Split a stereo MP3 into two mono files
Combine any two mono files (even unrelated) into a stereo MP3
Repair both audio channels (muted, etc...)  with extensive options, including detailed logging
(Typical processing time: 1–2 minutes for a 30 MB MP3)

In case of a new update available on http://sweiller.free.fr a blinking !!Update!! panel will light up at start!

Feel free to reach out via email for any questions, issues, or suggestions.


No installation is required!
Simply place the files in a non-system directory (e.g., `Users\SolarGun\...` or `Appexe\SolarGun\`).
Note that `.log` files, which records the work done, will be saved in the application directory.
