What is M4A?

M4A is AAC audio wrapped in an MP4 container. AAC is a more modern lossy codec than MP3 and generally sounds better at the same bitrate, which is why Apple chose it. If you record a voice memo on an iPhone, it almost always lands as an .m4a file, and the same goes for most Apple and many Android recording apps.

File size: A one-hour M4A at a typical voice-memo bitrate is around 30 to 60 MB, similar in scale to an MP3 and quick to upload.

How to convert M4A to text

1
Add your M4A file
Drag and drop your M4A audio file into LiteScribe, choose it from your device, or paste a link. M4A uploads directly with no conversion step, and large files use resumable upload so a dropped connection does not lose your progress.

LiteScribe returns a clean M4A transcript with speaker labels, timestamps, automatic punctuation, an AI summary, and topic tags. Pick the spoken language or let automatic detection identify it across 100+ languages.
3
Review, label, and ask AI
Read the transcript with each speaker labeled and every line timestamped. Rename speakers, fix any names or jargon, then ask the built-in AI to summarise, pull action items, or answer questions about what was said.
4
Export the text
Download your transcript as DOCX, PDF, or plain TXT, or export SRT subtitles to caption the original M4A recording. Copy any section straight into your notes, documents, or content.
