FileFix

What we can't repair — and where to go instead.

FileFix repairs corrupted audio files, but not every "broken audio" problem is a file-repair job. Some need a completely different kind of tool. We would rather tell you that up front than take your money for something we can't fix. Here's what we don't handle, why, and where to go instead.

Intro

FileFix repairs corrupted audio files, but not every "broken audio" problem is a file-repair job. Some need a completely different kind of tool. We would rather tell you that up front than take your money for something we can't fix. Here's what we don't handle, why, and where to go instead.

Section A — DRM-protected music: Purchased or streamed tracks locked to a store or app (Apple Music, protected AAC, and similar) are encrypted and tied to your account. They aren't corrupted — they're deliberately locked, and a file repair can't and shouldn't unlock them. For these, re-download the track from the service you got it from.

Section B — Deleted or formatted files: If the recording was deleted, or the storage was formatted, this isn't a repair problem — the file isn't damaged, it's gone from the file system. Getting it back is data recovery: carving the audio off the raw storage before it's overwritten. Stop using the device immediately and use a dedicated data-recovery tool. FileFix repairs files you still have; it can't bring back files that were removed.

Section C — Physically damaged phones, cards, or drives: If a phone, card, or drive is cracked, water-damaged, or not detected, the problem is the hardware, not the audio file. No software can read data off media that won't mount. This is a job for a physical data-recovery service. Once the data is safely copied off, if the audio file itself turns out to be corrupted, we're happy to try repairing it then.

Section D — Genuinely empty (0-byte) files: If a file is truly 0 bytes, there is no audio inside it — the recorder never wrote any sound. There's nothing to rebuild, and no tool can recover audio that was never recorded. If your file shows a real size but won't play, that's different and often repairable — try a repair.
