Transcribe M4A
Upload an M4A, the format Voice Memos and screen recordings use, and get a clean, speaker-labeled transcript in minutes. No conversion needed, 95%+ accuracy on clear audio. Test the quality free on your first 10 minutes. See the live accuracy benchmark.
A real transcript synced to its audio. Press play, or click any word to jump to that moment. Your M4A works the same.
Voice Memos, screen recordings, and many call-recording apps all save M4A (AAC audio in an MP4 container). If you recorded it on an iPhone, it's almost certainly an M4A. Send the file straight here, no export gymnastics. M4A is one of the formats the audio to text tool handles, alongside MP3, WAV and the rest.
No. Converting M4A to MP3 is lossy-to-lossy: it can only make the audio slightly worse, never better. FileToText reads M4A natively, along with WAV, MP3, AAC and most video formats, so skip the converter entirely.
Open Voice Memos, tap the recording, tap the three dots, choose Share, and save it to Files, then upload it here. You get a speaker-labeled, timestamped transcript with exports and a synced player. Recording interviews on your phone? The interview page goes deeper on multi-person audio.
