Frequently Asked Questions

What types of audio corruption can this tool fix?

This tool can fix: missing or damaged headers, corrupted timestamps (DTS/PTS), broken container structure, codec-level errors, truncated files, bitstream errors, and files that skip or glitch during playback.

What is the difference between Quick Fix and Deep Repair?

Quick Fix (remux) copies the audio stream into a fresh container, fixing header and timestamp issues without re-encoding — it's fast and lossless. Deep Repair fully re-encodes the audio, which fixes codec-level corruption but may slightly change quality. Auto mode tries Quick Fix first and falls back to Deep Repair.

What is the maximum file size?

You can upload files up to 50 MB. This covers most audio files including full albums in compressed formats.

Can this tool recover deleted audio files?

No. This tool repairs corrupted files that still exist but don't play correctly. It cannot recover permanently deleted or overwritten files.
