Turn your iPhone Voice Memos, podcast recordings, and M4A audio files into accurate, speaker-labeled transcripts. Upload, transcribe, export — done in minutes.
M4A is Apple's default audio format. Every time you record a Voice Memo on your iPhone, it saves as M4A. It's also the format used by GarageBand, iTunes downloads, and many podcast recording apps.
M4A uses AAC compression — the same codec behind Apple Music — delivering high-quality audio at roughly half the file size of WAV. This makes it great for recordings, but most transcription tools don't support it natively.
AudioTranscribe Pro handles M4A natively. Use our online audio transcriber to convert any format. No need to convert to MP3 or WAV first. Upload your M4A file directly and get a transcript with speaker labels, timestamps, and export options.
Drag and drop your Voice Memo or M4A file. Up to 200 MB, up to 120 minutes.
