To transcribe an M4A file, drop it into the box above; you don't need to convert it to MP3. Your browser reads the AAC audio, Whisper large-v3-turbo transcribes it, and your first file gets a free preview of the first 3 minutes. Unlock the whole file once, from $1.49 depending on its length, to download TXT, DOCX, SRT or VTT.

How to transcribe M4A

  1. Drop the M4A. Drag it onto the box above or tap to pick it. On iPhone, save voice memos to Files first. Google Drive and Dropbox share links work too.
  2. Read the preview. The audio is converted to 16 kHz mono in your browser and uploaded in short parts, then transcribed with timestamps.
  3. Unlock and download. Pay once for this file, priced by length from $1.49 (up to 15 minutes) to $4.99 (up to 120 minutes), and download TXT, DOCX, SRT or VTT.

Questions

How do I convert M4A to text?

Drop the M4A file into a transcription tool that reads M4A directly; there is no need to convert it to MP3 first. DropTranscribe opens M4A (AAC audio) in Safari, Chrome, Edge and Firefox, on phones and computers. It transcribes the speech with timestamps; the first 3 minutes of your first file are free, and the full file is unlocked once, priced by length from $1.49.

What is an M4A file?

M4A is an audio file in the MPEG-4 container, usually with AAC compression. It is the default format of iPhone Voice Memos, many Android recorder apps, Zoom's audio-only recording and audio exported from GarageBand or iTunes. Because it is the same container as MP4 video, most browsers and players open it without any conversion.
