How It Works
Fix corrupt mp3s in four steps
3vise uses the MP3val engine to scan every frame of your mp3 files, identify corruption, and repair it in place. No re-encoding, no quality loss, no internet required.
Drag your files
Drag mp3 files or entire folders into the 3vise window. Process hundreds of files at once.
Scan for corruption
3vise analyzes every frame of each mp3, flagging invalid headers, truncated data, and structural problems.
Repair in one click
Hit Repair to fix all flagged issues. Corrupt frames are removed or rebuilt without re-encoding your audio.
Scrub metadata (optional)
Strip non-essential ID3 tag data that can bloat file sizes. Core tags like title, artist, and BPM are always preserved.
Powered by MP3val
