Convert M4A to text
Voice memos and other AAC recordings become editable words on this page. Weeve decodes the file locally, detects the language automatically, and writes a transcript you can copy or export.

Compatibility at a glance
Weeve accepts .m4a files and the audio/mp4, audio/x-m4a, and audio/m4a MIME types. M4A is a container, so the browser must support the AAC or other codec stored inside it.
- .m4a
- audio/mp4
- audio/x-m4a
- audio/m4a
How it works
Four clear steps from local file to reviewed text.
- 01
Save the recording
Export the voice memo or other M4A recording to your device.
- 02
Select it here
The browser decodes the audio on this page without an upload step.
- 03
Read the words
The model writes punctuated, timestamped text in the detected language.
- 04
Copy or export
Move the text into notes or documents, or export it as a file.
Product details
Practical details for m4a to text.
Voice memos as usable text
Ideas, meeting recaps, and field notes spoken into a phone are hard to search as audio. As text they become something you can scan, quote, and file.
Save or share the memo as a file first. Weeve has no connection to iCloud or the Voice Memos library and only reads the file you select.
What the converted text includes
The draft carries punctuation, capitalization, and word timestamps. Speaker separation adds numbered labels for up to 8 voices, which you can rename before exporting.
Exports are available as plain text, Markdown, and PDF, and they reflect the transcript as you reviewed it.
When an M4A will not convert
Protected files and unusual codec variants can fail to decode even with a supported extension. Export a fresh, unprotected copy from the source app and try again.
Renaming another format to .m4a does not change the codec inside. Convert a copy to WAV or MP3 instead if decoding keeps failing.
Your recording stays here
Recording bytes, decoded audio, transcript text, and speaker names stay on this page. Speech models download from Weeve’s CDN.
A transcript you can review
Timestamps and speaker labels stay editable before export.

Great. I renamed your speaker label, so the exported notes will use your name.
