M4A is what your iPhone records
When you tap record in Voice Memos, or capture audio in many other Apple apps, the file lands as an M4A wrapped in AAC compression. It is efficient and high quality, which is why Apple picked it, but plenty of transcription tools still refuse to open it.
FastScribe accepts M4A straight from your phone or Mac with no conversion step. AirDrop or email the memo to your computer, drop it in the box above, and you get a timestamped transcript back without touching a converter or command line.
From memo to usable notes
A raw voice memo is hard to search and slow to review. Turning it into text lets you skim an hour of thinking in a minute, copy the good parts into a document, and keep a written record you can actually find again later.
Choose TXT for quick notes, SRT or VTT if the memo pairs with video, and DOCX on Pro when you want formatting. Timestamps stay attached to every export so you can always trace a line back to the original recording.
Frequently asked questions
Do I have to convert M4A to MP3 first?
No conversion is needed at all. FastScribe reads M4A directly, so you can upload an iPhone Voice Memo exactly as it was recorded and get text back with timestamps.
How do I get an M4A off my iPhone?
Open Voice Memos, tap the share icon on a recording, and AirDrop or email it to your computer. Then drop that M4A into the upload box above to start.
How accurate is the transcript from a phone recording?
Clear speech comes back highly accurate on phone audio. Heavy background noise or several people talking over each other will lower it somewhat.
