"This file isn't playable…" — what the audio error means.

"This file isn't playable…" means the player could not recognize or decode the audio structure it received. Upload the file for a repair attempt and hear a free preview first if FileFix can produce a playable result.

Repair your file

You preview before you pay. If the download is materially worse than the preview you approved, we'll refund you.

Good news — your file isn't damaged. No charge.

There's nothing to repair. If it still looks broken, the issue may be the player, codec, or viewer on your device rather than the file itself.

We couldn't recover this one.

The file is too damaged to rebuild, so there is nothing to preview and no charge. You can try another file.

FileFix can't fix that kind of file yet.

Right now we repair video, audio, and document files (MP4, MOV, M4V, MKV, AVI, TS, MTS, M2TS, MPG, MPEG, VOB, 3GP, WebM, M4A, WAV, MP3, AAC, FLAC, OGG, AIFF, XLSX, DOCX, ZIP, and PDF). We're adding support for more formats over time.

We store just your email and the file type — never the file itself. One message, when it's ready. No spam.

Why an audio file isn't playable

A player needs a recognizable container or stream header, valid frame boundaries, and codec data that agrees with that structure. An interrupted save or transfer can remove the closing index, truncate a frame, or leave length and offset fields pointing beyond the available bytes.

The message is broad because the player reports the decoding failure rather than the damaged field. Container-based recordings can still hold audio payloads when their index is missing, while raw streams can fail when framing bytes are incomplete or inconsistent.

FileFix analyzes the uploaded file and only offers checkout when it produces a playable result. You hear a free watermarked preview and see how much was recovered; genuinely empty, deleted, or DRM-protected files cannot be repaired.
