AI TranscribeCAF to text: how to transcribe .caf files on iPhone
You have an iOS app recording — Core Audio Format is built for very long recordings — 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 .caf directly.
Short answer: Import the file into AI Transcribe — tap Import, choose Audio File, pick your .caf 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 .caf file?
CAF (Core Audio Format) is Apple’s container for long-form audio — GarageBand and many iOS recorder apps use it because it has no practical size limit. Long lecture or session recordings often arrive as .caf.
CAF to text, step by step
- Get the file onto your iPhone (Files, Downloads, or shared from another app).
- Open AI Transcribe and tap Import → Audio File.
- Select the .caf file. It’s converted and transcribed automatically — keep the app open while it processes.
- 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 .caf 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.
