FOUR-STEP WORKFLOW
How to convert FLAC to text
Use one workspace from direct FLAC upload to source-backed review and export.
- 01
Upload the FLAC file
Choose one playable FLAC file up to 5 GB. No MP3 or WAV conversion is required.
- 02
Choose the settings
Select a language or auto detect, then add speaker recognition, context, or key terms if useful.
- 03
Run the transcription
Sign in, confirm the estimated credits, and let processing continue in the background.
- 04
Review and export
Check the draft against the lossless source, edit the text, and export TXT, Markdown, SRT, or VTT.
COMPARE WITH THE SOURCE
Review every uncertain phrase against the FLAC source
Keep the FLAC source beside the draft. Replay uncertain wording, check low-confidence phrases, rename speakers, and save the corrections before export.
- Replay the FLAC source without leaving the transcript
- Inspect low-confidence phrases against the original recording
- Rename speaker labels without treating channels as speakers
- Edit segments and save the revision before export
LOSSLESS DOES NOT MEAN ERROR-FREE
What FLAC preserves—and what it cannot fix
Lossless compression preserves the signal it receives; it does not repair the recording. Start with the clearest source, check its size and properties, then review the draft against the audio.
Preserved is not repaired
FLAC keeps the information present at encoding time, but it cannot undo clipping, noise, overlap, or detail lost in an earlier source.
Plan for larger files
Check the file against the 5 GB limit. A lossless copy may be larger than the MP3 or AAC version of the same recording.
Capture distinct voices
Clear speech, sensible microphone placement, and less overlap matter more than simply raising sample rate or bit depth.
Describe the words
Choose the spoken language, add important names as key terms, and use speaker recognition when labels help; channels and speakers are not interchangeable.
PRESERVE THE RECORDING, USE THE WORDS
Where FLAC transcripts earn their place
FLAC is often kept when the original signal matters. The transcript adds a searchable, editable layer without pretending to improve the audio.
Archives and oral histories
Turn lossless preservation copies into searchable text while keeping the recording available for comparison.
Field-recorded interviews
Review quotations against a recorder export and rename speaker labels for a readable conversation.
Spoken-word masters
Create working text or timed captions from voice-over, podcast, or production masters without claiming audio restoration.
Meetings and research sessions
Make long recordings easier to search, revise, and export while preserving the source context.
FLAC TRANSCRIPTION FAQ
Before you convert FLAC to text
Clear answers about lossless audio, file properties, credits, review, exports, and source-file access.
Yes. FLAC is accepted directly, so you do not need to convert the recording to MP3 or WAV first.
No format guarantees accuracy. Lossless compression preserves the audio information already in the source, but it cannot repair clipping, background noise, distant voices, or overlapping speech.
No. Saving a lossy or damaged source as FLAC does not recreate information that was already removed. Use the clearest original recording you have.
They describe the source recording, but higher numbers do not automatically produce a better transcript. The service does not promise resampling, bit-depth conversion, channel splitting, or one speaker label per channel.
The per-file upload limit is 5 GB. FLAC files can be larger than common lossy versions, so check the size before uploading one file at a time.
You create an account to start. New accounts receive 10 signup credits with no credit card required; one credit covers one minute of transcription.
The service supports 99 languages. Choose the spoken language or use automatic detection, and enable speaker recognition when separate speaker labels would help. Speaker labels are not the same as audio channels.
You can export TXT, Markdown, SRT, or VTT after the transcript is ready.
The source media remains available for review for up to seven days from task creation. You can delete it sooner; saved text remains available for review and export.
KEEP THE SOURCE, SHAPE THE TEXT
Turn a lossless recording into working text
Upload a FLAC recording, review the draft beside the lossless source, and export text or captions you can keep refining.
