M4A transcription

M4A to text, with a transcript you can actually use

Upload a M4A file for iPhone Voice Memos, Apple Podcasts downloads and AAC recordings and get a timestamped transcript, a summary and subtitle files. Nothing needs to be installed, and you can start with the free daily allowance.

M4A usually contains AAC audio. iPhone voice memos are mono and speech-optimised, which makes them a good fit for transcription.
