On this page
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 20+ AI tools on the result, or export the transcript as text or PDF.
On a Mac or in a browser
On a Mac, drag the .caf file onto AI Transcribe for Mac, or press ⌘I to import it; the transcript and the AI tools work the same way. Sign in with your email and every transcript also opens in the web library on any computer, where you can read it, export it as text, Markdown or subtitles, or share it as a link.
