MP3 plays but no sound or cuts out partway

Repair your file

Choose a supported file to see what can be repaired before checkout.

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 MP3 has no sound or cuts out

MP3 audio is stored as a sequence of frames, each with a header that tells a decoder how to interpret the following compressed data. A damaged header or truncated frame can make playback lose synchronization, stop partway, or decode no usable sound.

Frame resynchronization searches for the next valid frame boundary and preserves decodable frames after damaged bytes. Audio contained only in missing or incomplete frames cannot be recreated, so the recovered result may be partial.

FileFix analyzes the uploaded MP3 and only offers checkout when it produces a playable result. You hear the recovered preview first; genuinely empty, deleted, or DRM-protected files cannot be repaired.
