FLAC to Text

Lossless in, text out. The archive stays exactly as you preserved it.

Three steps

How does FLAC to Text work?

Step 1: Upload or drop the file

Drag your .flac into Speech to Text. Uploads up to 25 MB per file.

Step 2: A Whisper-class model transcribes

The audio goes to a Whisper-class model and the transcript comes back in the same view, usually within seconds.

Step 3: Copy, download, or save

Copy the text, download it as .txt, or save it to your library next to the source audio.

The format

What is a FLAC file?

FLAC compresses audio the way ZIP compresses documents: perfectly reversibly, usually to around half the size of the WAV it came from. Checksums ride inside the file, so corruption announces itself instead of hiding, which is precisely why digitization projects and careful archivists standardized on it.

For transcription, FLAC hits a sweet spot WAV cannot: identical samples in roughly half the bytes, so close to twice the minutes fit under the 25 MB cap. An oral-history interview preserved as FLAC uploads exactly as it sits in the collection; nothing needs decoding, converting, or unpacking on your side first.

Who keeps speech in FLAC

  • Digitization programslibraries and oral-history projects converting tape to disk choose FLAC for verifiable, lossless storage.
  • Live-recording circlescommunities that tape and trade concerts and talks distribute the masters in this format.
  • Careful personal archivistspeople keeping one canonical copy of an important recording pick FLAC for the built-in checksums.
  • Storage-conscious studiosa FLAC of the session master is bit-identical to the WAV at about half the disk.
The honest specifics
  • Uploads up to 25 MB per file
  • Reads .flac
  • Output: plain text, as a copyable transcript or a .txt download
  • No watermark, yours to keep
Straight answers

FLAC to Text questions, answered honestly.

Does FLAC give a better transcript than MP3?
Honestly, rarely enough to notice. Lossless audio earns its keep in preservation and editing; a Whisper-class model extracts the same words from a well-made MP3 of the same recording. Use FLAC because you have it, not because the transcript demands it.
How much FLAC audio fits under the 25 MB cap?
Roughly double what WAV would manage: on the order of five minutes of CD-quality stereo, and somewhere around a quarter hour of 24 kHz mono speech. FLAC's ratio shifts with the material, so treat both figures as estimates rather than promises.
Will transcribing alter or re-compress my FLAC?
No. The file is read, the words come back, and your original stays byte-for-byte what it was. The transcript is a separate plain-text artifact you can copy, download, or save alongside the audio.
Why do archives insist on FLAC anyway?
Three reasons that compound: nothing is lost in encoding, the format is open and will outlive any one vendor, and the internal checksums make silent corruption detectable decades later. Insurance, in file form.
