Why use M4A to Text?
Built for M4A audio
M4A files come from Apple's preferred AAC-encoded audio container. Our pipeline decodes them directly. No manual conversion to MP3 needed first.
99% accuracy
Premium-grade AI transcription served on dedicated GPUs. Handles accents, overlapping speech, and noisy recordings.
99+ languages auto-detected
Spanish, French, Arabic, Mandarin, Wolof, Swahili. You don't pick the language, we detect it from the audio.
Speakers, timestamps, summary
Every transcript comes with speaker labels, clickable timestamps, and an AI-generated summary with action items and an email draft.
How it works
Upload your M4A file
Drag & drop your .m4a file, or paste a URL. First 30 minutes free; paid plans process the full file.
AI transcribes it
Our AI pipeline handles M4A audio natively. Typical 1-hour file finishes in 2-4 minutes.
Export, edit, share
Download as TXT, SRT, VTT, or JSON. Edit in the browser with full speaker management and one-click email drafts.
