Audio recovery options and guides.
FileFix repairs audio files that won't open, play as silence, or stop partway.
Free preview — pay only if you download ($8 USD)
Your files auto-delete — delete them sooner anytime

Here's what we recovered.
Review the watermarked preview before checkout. It is up to 12 seconds sampled from the start, middle and end of your recording.
Repair your file
Choose a supported file to see what can be repaired before checkout.
Simulated checkout — no payment is processed.
Optional — we'll email your private download link.
You preview before you pay. If the download is materially worse than the preview you approved, we'll refund you.

We couldn't recover this one.
The file is too damaged to rebuild, so there is nothing to preview and no charge.
What stopped you continuing? One tap tells us why.
Try a deep repair
The repair engine can try a longer pass on the file you already uploaded.
Machine-only processing; no human views files; nothing is sent to an outside AI.
Have another clip from the same device?
A healthy video recorded on the same device — ideally the same settings — gives the repair engine a template to rebuild from. It can unlock repairs that fail on their own.
Unrepaired files are kept encrypted for up to 30 days, then deleted.
FileFix can't fix that kind of file yet.
Right now we repair video, audio, document, and image files (MP4, MOV, M4V, MKV, AVI, TS, MTS, M2TS, MPG, MPEG, VOB, 3GP, WebM, FLV, M4A, WAV, MP3, AAC, FLAC, OGG, OPUS, AIFF, XLSX, DOCX, PPTX, ODT, ZIP, RAR, PDF, AI, HEIC, and HEIF). We're adding support for more formats over time.

The most common ways audio files break
An interrupted recording or transfer can leave the file's header wrong. Upload the file in your browser, listen to a free watermarked preview clip of the rebuilt audio, and pay only if the repair worked.
Most "broken" audio files aren't actually gone. The sound is still sitting inside the file — but the small part that tells a player where the audio starts, what format it's in, and how long it runs got damaged or was never written. That happens when a recording is cut off, a phone dies mid-capture, a transfer is interrupted, or an app crashes before it finishes saving.
FileFix reads what's actually in the file, rebuilds that missing structure, and re-assembles the audio into a file your player can open. When the structure is the problem, this works well. When the audio itself is truly gone — a genuinely empty file, or a recording that never captured sound — there is nothing to rebuild, and we tell you that instead of taking your money.
You never install anything. You never create an account to try it. You upload, you listen to the preview, you decide.
What we can and can't recover
We can usually fix
- Audio files that won't open, show an error, or play as silence
- Recordings that were cut off, interrupted, or never finished saving
- Voice memos and recordings off phones, laptops, and recorder apps in supported audio formats
- Files that show the right size but won't play
We can't fix
- Genuinely empty (0-byte) files — there's no audio inside to rebuild
- DRM-protected tracks (purchased/streaming music locked to an account or app)
- Deleted or formatted files — that's data recovery, a different job
- Physically damaged phones, cards, or drives

How it works
-
Upload Drop a supported audio file in. It uploads over an encrypted connection. The repair runs automatically — no person listens to your file.
-
Free watermarked preview You hear a free watermarked preview clip and see exactly how much we recovered.
-
Pay & download If it's right, you pay $8 USD once and download a clean, full-quality audio file.
About half of real-world corrupted files repair fully — and you hear a free preview before you pay, so you never guess.

Questions
You upload an audio file that won't open or play, and we try to rebuild it into a working file. Before you pay anything, you hear a free preview of what we recovered. If the preview sounds right, you pay once and download the full-quality playable audio file. If we couldn't recover it, there's nothing to preview and no charge.
WAV and M4A repair best today. MP3, AAC, FLAC, OGG, and AIFF are accepted for analysis, but the current repair engine may decline them. You see the outcome before checkout and pay nothing when we cannot rebuild the file.
You pay once, per file, only after you've heard a free preview of what we recovered. The price is shown on the button before you click it. No subscription, no account, no charge if we couldn't fix your file.
No. The preview is free and always comes first. You listen to what we recovered, then decide. We built it this way on purpose — you should hear exactly what you're getting before any money changes hands.
The preview is a shortened clip with a periodic audio watermark — you can listen to it but not download it. It's there so you can judge the result before paying. When you check out, the watermark is removed and you get the full-length, full-quality audio file. The watermark is just how we keep the free preview honest — it isn't the finished file.
When a repair is fully successful, yes — you get the full length back. The preview tells you exactly how much we recovered, in plain numbers: for example, "Recovered length: 86s of 86s." If only part of the audio could be saved, we show that too — "Recovered length: 12s of 86s" — and the free preview plays only a limited sample of the recovered audio; the recovered length describes the repaired file. You decide whether a partial recovery is worth paying for. We never dress up a partial as a full recovery.
Then we tell you, plainly, and you're not charged. Some files are too damaged to rebuild — the data needed to play them is gone, not just scrambled. When that happens there's nothing to preview and no payment. You're welcome to try another file.
No. The repair runs automatically, start to finish. No person opens or listens to your file as part of the process. That's true by how the system is built, not a promise we hope to keep.
Your file is uploaded over an encrypted connection and processed automatically. We keep the original of a repaired file encrypted (never viewed by a person) only while you can still buy it or ask for a refund: until your repaired file is deleted, and no more than 2 days after you pay. That lets us try a fuller repair if you ask. Then it is permanently deleted. Files we can't repair are kept encrypted — never viewed by a human — for up to 30 days, then permanently deleted. You can delete yours sooner anytime. After you pay, you can re-download your repaired file for 48 hours — 7 days if you gave us your email — then it's deleted automatically. Repairs you don't buy are deleted 48 hours after upload (7 days if you gave us your email). If we re-run a failed repair and it succeeds, the new result is kept 48 hours from then (7 days if you gave us your email). The full repaired file is locked on our side until your payment clears, then released to you through a private download link. We don't post, share, or publish your file anywhere.
No. Before you upload, you confirm you have the right to the file and that it contains no illegal content. Only upload files that are yours or that you're allowed to work with.
Yes, up to 2 GB. Uploads use one automatic flow, so there is no size option to pick. If a file is too large, we tell you before repair starts.
Usually under a minute for audio, depending on the size of the file. You'll see when it's done, and you can leave the page open in the meantime.
Because you hear the preview before you pay, most surprises are handled up front — you already heard what you were buying. If something still goes wrong with a file you paid for, see our refund policy.
