Recordings are urgent in a way music is not
A deleted album can be downloaded again. An interview, a lecture, a rehearsal take or a voice memo cannot — it exists once. If what you lost is a recording, treat the card or drive as evidence: take it out of the recorder, stop writing to it, and scan it from a computer.
Field recorders and phones are especially quick to reuse free space, because they write large files continuously. Every extra minute of recording after the loss is a minute of your old audio being overwritten.
Which formats come back
RecoverHelper carves MP3, WAV, FLAC and OGG by signature. WAV and FLAC are typically the large uncompressed or losslessly compressed files a recorder produces; MP3 and OGG are what music libraries and voice apps tend to hold.
Alongside audio, the same scan picks up video (MP4, MOV, M4V, MKV, AVI, WebM), photos, camera RAW, documents and archives — useful when a card held a mix of takes and reference shots.
Tags and filenames: what survives
This is where audio differs from photos. Music libraries lean on filenames and folder structure (Artist/Album/01 Track.mp3) as much as on tags.
- Quick Scan on NTFS — restores names, folders and timestamps, so a library comes back organised.
- Carving (Deep Scan or Carving Only, and the only option on FAT32/exFAT cards) — recovers the audio itself with a generated name. ID3 tags stored inside the MP3 file survive, since they are part of the file, so a media player can often re-sort your library even when the filenames are gone.
Scanning a card or recorder safely
- Remove the card and connect it through a card reader rather than recording anything else.
- Open RecoverHelper, select the card, and set the destination to your computer's drive — never back onto the card.
- Choose Carving Only for a card, or Quick Scan first if the audio was on an internal NTFS disk.
- Preview and restore. If the card is failing, bad-sector tolerance skips unreadable areas and keeps going.
Audio recovery is unlocked for free by pairing the free RecoverHelper mobile app — there is nothing to buy.
