Repair Corrupted Audio Files Online

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.

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.

The ones where the audio itself survived and only the bookkeeping around it broke: a header that no longer describes the file, timestamps that jump backwards, frames that were cut mid-way, and in WAV the specific fault of a RIFF size field that disagrees with the data actually present — which is what a copy interrupted halfway leaves behind. The diagnosis runs first and tells you which of those it found, so you know before you start whether there is anything to repair.

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

Usually not. When every field reads Unknown, the file has no WAV header at byte 0 — an interrupted bounce, a data-recovery copy, or a disk that failed while writing. The audio itself is often intact right behind the missing header. The tool now inspects the bytes, detects the bit depth, channel count and byte order, and offers to rebuild the header. The one thing bytes cannot tell is the sample rate: pick the rate the recording was made at (44.1 kHz for most music, 48 kHz for video work) and use the 10-second preview — at the wrong rate the pitch and tempo are visibly off. If the tool reports only digital silence or no recognizable audio data, the recording was never written to that file, and no lab can bring it back from there.
