About FLAC files
FLAC is lossless compressed audio — smaller than WAV with identical quality, popular for archives and high-quality recordings.
Common sources: archival and oral-history collections, high-quality recorder exports, studio masters.
Chrome, Edge, Firefox and Safari all read FLAC.
FLAC to text
Archive recordings often have hiss or hum; transcription still works, but reducing noise first improves accuracy.
A library digitises an 85-minute oral-history tape as FLAC and transcribes it for its catalogue.
Cost: 85 credits (8.5¢).
Translating a FLAC
For archives, a translated transcript (text-only) is usually more useful than a translated voice track.
A museum translates a 35-minute FLAC oral history from Polish into an English transcript for an exhibition.
Cost: 1,750 credits ($1.75) with a translated voice, or 35 credits (3.5¢) for translated text only. Switch Full translation output on in the tool above for a voice track.
Using the tool on this page
- The spoken language is detected automatically; you select the output language — the spoken language itself for an untranslated transcript, or another language for a translation. Files can be up to 2 hours long.
- Audio is sent over HTTPS in small chunks and deleted with its transcripts within 30 minutes of delivery (how files are protected).
- You can download a timestamped transcript, subtitles (SRT and VTT) and plain text. Every output, step and limit is explained on the audio to text page.
Frequently asked questions
Do I need to convert FLAC to MP3 first?
No. FLAC is read directly in the browser.
Is a lossless translated file available?
The translated voice is delivered as M4A (AAC). Transcripts and subtitles are lossless text, of course.
