FLAC to text: how to transcribe .flac files on iPhone

You have a lossless archive or a field recorder — and you need the words in it as text. You don’t need a converter, an mp3 tool, or a desktop app: transcription apps accept .flac directly.

Short answer: Import the file into AI Transcribe — tap Import, choose Audio File, pick your .flac file — and the transcript appears with timestamps and speaker labels. Files up to 3 hours are supported, and the format is converted internally, so no preparation is needed.

What is a .flac file?

FLAC is lossless compressed audio — archives, audiophile rips and many field recorders use it. Files are large but nothing is thrown away; for transcription, the fidelity headroom simply means clean input.

FLAC to text, step by step

1. Get the file onto your iPhone (Files, Downloads, or shared from another app).
2. Open AI Transcribe and tap Import → Audio File.
3. Select the .flac file. It’s converted and transcribed automatically — keep the app open while it processes.
4. Use Summarize or any of the 15+ AI tools on the result, or export the transcript as text or PDF.

Frequently asked questions

Do I need to convert .flac to another format first? No. Conversion happens inside the app; any common audio format works.

How long can the file be? Up to 3 hours per file. Transcription takes minutes, not the file’s duration.

Which languages are supported? 32 languages with automatic language detection — the file’s language doesn’t need to be set manually.

What does it cost? AI Transcribe is free to download and try; the Pro subscription (weekly or annual) unlocks up to 3 hours of transcription per day.
