Tascam file not finalized? Recover the recording.
A Tascam or other recorder WAV that was never finalized won't open on your computer. Upload it as it came off the card: we write the missing lengths from the audio that is there and you hear a free preview before you pay.

We couldn't recover this one.
The file is too damaged to rebuild, so there is nothing to preview and no charge.

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.

What is missing from an unfinalized Tascam WAV
Finalizing a WAV means completing its header lengths when the take ends. A Tascam recording interrupted before that step can have a file name and recorded samples, yet still lack usable RIFF and data lengths. An interruption does not by itself tell you how much audio was saved.
The useful distinction is between an unfinished header and missing audio. FileFix can write consistent lengths around samples that remain in the WAV; it cannot supply samples the recorder never saved. A file larger than 0 bytes is worth checking, but its size alone does not prove that a take is recoverable.
Keep the original card file and upload an unchanged copy rather than a re-saved or converted version. The recovered preview lets you check the available audio before paying. An empty 0-byte copy contains nothing to finalize or repair.
What we can and can't fix
We can usually fix
- Unfinalized Tascam WAV files with audio samples still present but missing or incorrect RIFF and data lengths.
We can't fix
- 0-byte Tascam files, or parts of a take never written to the card; completing a header cannot add missing audio. More →

Questions
The WAV header was not completed with usable RIFF and data lengths when recording ended. A Tascam file can still contain samples even when a player cannot read its duration, but finalization cannot replace audio that was never saved.
Copy the original WAV off the card and keep that original unchanged. Upload the copy before re-saving or converting it in an editor, which can discard samples hidden by the unfinished header.
No. Rebuilding the lengths makes the samples that remain readable; it cannot fill gaps or extend the take beyond what was saved. Listen to the free preview to check the recovered portion before you pay.
No. That file contains neither a WAV header nor recorded samples. Check whether the original on the card is larger than the copy; if you find a nonempty original, upload a copy of that file. There is no charge for an empty file.
