M4A to SRT
M4A to SRT
Make an SRT from an M4A recording. Useful when you have podcast audio, a Voice Memo or a Zoom audio file and want timed captions for a video made with it, or a subtitle track for an audiogram.
Why subtitles from audio
Audio has no picture to carry captions, so the SRT is for the video you build around it: a podcast clip on Instagram or YouTube, an audiogram, a slideshow lecture. Because the times come from the audio itself, the SRT lines up with that audio wherever you use it, as long as the video you build starts at zero with the same audio.
Steps
- Upload the M4A above.
- Fix the transcript against the audio.
- Export SRT.
- Import it with your audio into the editor or audiogram tool; each tool has its own import-captions menu.
Cut your audio first
If you only need captions for a 60-second clip, trim the audio before upload: the transcript then starts at 0:00 and the SRT needs no shifting. If you transcribe the whole file and cut a clip later, use the time shifter to subtract the clip's start time from every cue.
Readable caption lines
Recognition segments follow pauses in speech, not screen width. For social video with large text, re-wrap long cues to a shorter line length with the subtitle line splitter.
How it works
Add a recording
Drop in a video or audio file, choose one from your device, or record from the microphone. Nothing to install.
It transcribes
Speech becomes timestamped text, with speaker labels when more than one person talks.
Read, fix, export
Click any line to correct it, then download TXT, subtitles, Markdown, JSON or CSV.
