M4A transcription

Convert M4A to text

Transcribe an M4A voice recording without converting it first. Get a plain-text transcript or timed SRT and WebVTT captions from English speech.

Unlimited free transcription. Fair use applies

How it works

  1. Export the M4A recording to your device's file storage.
  2. Choose the audio file here and check its preview.
  3. Run transcription, then copy the text or download TXT, SRT, or VTT.

After transcription, download plain text, SRT subtitles, or WebVTT captions from the same result.

Best fit

M4A is commonly used for phone voice memos and compressed audio recordings. Export or share the actual audio file from the recording app before uploading; a sharing-page URL is not an audio file.

Uploads use private temporary storage and are deleted after processing. Signed-in users receive a private saved transcript plus TXT, SRT, and VTT copies; signed-out results stay only in the current tab. Review the privacy policy before using sensitive material.

What to expect from this conversion

Original audio file

Some recording apps share a link instead of a file. Use an export or save-to-files action to get the M4A itself. SceneDub accepts uploaded media, not private cloud-sharing links.

Review short recordings

Voice memos often begin mid-sentence or contain names with little context. Check the opening words, proper nouns, and spoken numbers before adding the result to notes or sending it to someone else.

File compatibility

M4A is a container and some encodings may not be readable. If a valid recording fails, export a WAV or MP3 copy in your audio application. Uploading the same unreadable bytes under a different name will not fix the codec.

Frequently asked questions

Can I transcribe an iPhone voice memo?

Yes, when you export it as a supported audio file such as M4A. Upload the file rather than a link to the recording app.

Does the recording stay public?

No. Uploaded media uses private temporary storage and is removed after processing. Signed-in accounts can save the generated transcript and subtitle files privately.

What does Audio transcriber do?

SceneDub converts English speech in an uploaded audio or video file into a transcript. Download TXT for notes, SRT for subtitle editors, or VTT for web players. Speech recognition creates a draft: check names, numbers, and unclear passages against the recording before sharing.

Input
English speech in MP3, WAV, M4A, MP4, OGG, or WebM
Output
Editable transcript, TXT, SRT, and WebVTT
Processing
Cloud speech recognition; private temporary media upload

A practical workflow

  1. Choose the original recording with the clearest speech.
  2. Run transcription and compare the draft against the audio.
  3. Download the format your next step needs; signed-in results also appear in Saved.

One recording, three useful exports

Input / starting point

Spoken audio: Welcome to the recording.

Output / result

TXT: readable notes
SRT: numbered subtitle cues
VTT: a web caption track

This illustrates the export choices, not a promised recognition result. Downloaded subtitles contain timestamps; plain text does not.
