What is M4A to Text?
M4A to Text converts M4A recordings such as iPhone Voice Memos, phone interviews, and lecture captures into editable text. The file is processed as recorded, without an MP3 conversion step, so transcription runs on the original audio. Language is detected automatically, speakers can be separated on two-person interviews, and the result can be corrected and exported as plain text or subtitles.
Why choose M4A to Text?
M4A to Text is built around the way phone recordings accumulate: short memos, hour-long interviews, and lecture captures in the same container. Each file can be added straight from a phone or a synced folder, and the transcript keeps timestamps, so a passage can be found in the audio without listening from the beginning.
Still Listening Back Through Every M4A Memo to Write It Down?
Phone recordings pile up because listening back costs as much time as recording did. Memos from a commute, hallway interviews, and lectures stay in a synced folder until someone finds an hour to type them out. M4A to Text returns a timestamped transcript in minutes, so a memo becomes a searchable note instead of an unopened file.
What makes M4A to Text different?
M4A to Text takes the recording as the phone saved it. Timestamps stay attached to each passage, long memos remain navigable, and speaker labels keep a two-person call readable instead of running every voice together.

Frequently asked questions about M4A to Text
Does M4A to Text work with iPhone Voice Memos?
Yes. A Voice Memo is an M4A file, so it can be uploaded as it sits on the phone or after it syncs to a computer. Shared memos arrive with a generic name, which is worth renaming before transcription so a folder of recordings stays identifiable later. There is no need to export through another app first.
Is the audio converted to MP3 before transcription?
No. M4A to Text sends the file as it was recorded, so the transcription runs on the original AAC audio rather than a re-encoded copy. That keeps the speech as clean as the phone captured it, avoids a second file on disk, and shortens the path between recording the memo and reading the text.
How long can an M4A recording be?
A single file can run up to three hours, which covers a long lecture or a full interview session, and the upload limit is 100MB. Longer material is better split at a natural break, such as a lunch adjournment, since a transcript is easier to review in the same segments as the recording.
Can two speakers be labeled in the transcript?
Yes. With speaker separation enabled, each turn is attributed, so a reporter and a source do not blur into one voice. Labels arrive as generic speaker numbers and can be renamed to real names in the editor, which keeps a quote attributable when the transcript is pasted into a draft.
How accurate is an M4A transcription?
A memo recorded close to the mouth with little background sound needs only light correction. A phone left on a table in a cafe produces more errors, and names, places, and jargon are the usual suspects. Reading the transcript against the timestamped audio for a minute or two is enough to judge whether a file needs a full review.
Can the transcript be edited and exported?
The text is editable before anything leaves the page: wording, punctuation, speaker names, and paragraph breaks. Export options cover plain text for notes and SRT when the recording will carry captions, so one interview can serve both a written draft and a subtitled clip without a second transcription run.
Is there a file size or daily limit?
Uploads are capped at 100MB per file, and the daily allowance depends on whether a user is signed in; an account raises the ceiling and keeps history. A long interview series is therefore best spread across a few days or handled with an account rather than submitted as one enormous batch.
Can subtitles be produced from an M4A file?
Yes. Because the transcript carries timestamps, it can be exported as an SRT caption file even though the source is audio only. That is useful for a podcast episode or a voice-over that will later be paired with video, where captions have to be ready before the picture edit is finished.
