aac transcription in three steps
Upload an AAC file, let the browser extract and compress audio, then review and download a timed TXT, SRT, or VTT transcript.
Prepare and upload
Select a recorded AAC file from your device; SubTran uses the Web Audio API to extract the audio track locally before sending anything.
Automatic transcription
The browser compresses and splits long files into ten-minute chunks, then OpenAI Whisper performs speech-to-text with word-level timestamps.
Preview and export
Edit the editable preview, choose TXT, SRT, or VTT, and download captions or a TXT transcript with preserved cue timings.
