WAV to SRT

Create an SRT file from a WAV recording: upload the audio, correct the transcript, export timed subtitles. Typical for field recordings and edited podcasts that you keep as WAV masters.

Subtitles from a master recording

If your edit lives as a WAV, subtitles made from that same file line up exactly with the audio in your final video, provided you do not change speed or add an intro. Add an intro of N seconds later and every cue needs shifting by N; the subtitle time shifter does that in one step.

Steps

  1. Check the size: CD-quality stereo WAV is about 10.6 MB a minute, so 2 minutes fits the no-account preview. Longer needs a smaller copy or an account.
  2. Upload the WAV above.
  3. Correct the transcript; export SRT.
  4. Load the SRT in your video editor.

Shrinking the file first

Convert a copy to M4A or MP3 with the audio converter. Voices are unaffected for recognition purposes and the upload is a fraction of the size.

Frame rates

SRT times are in clock time, not frames, so a 24, 25 or 30 fps project reads the same file. If your video was exported at a slightly different speed (a 23.976 to 25 fps conversion, say), cues drift progressively; the shifter's stretch option handles that.

How it works

  1. Add a recording

    Drop in a video or audio file, choose one from your device, or record from the microphone. Nothing to install.

  2. It transcribes

    Speech becomes timestamped text, with speaker labels when more than one person talks.

  3. Read, fix, export

    Click any line to correct it, then download TXT, subtitles, Markdown, JSON or CSV.

Questions

Is WAV better than MP3 for subtitles?
No difference you should plan around. Clear speech wins.
Why is my WAV rejected?
Usually the size cap or the length cap; see the steps above.
Does the SRT have one line per sentence?
Each transcript segment becomes one subtitle cue with its start and end time, as the recogniser produced it. Some cues can be longer than a screen likes; the free subtitle line splitter re-wraps them in your browser.
Is it free?
Yes — one file up to 15 minutes and 25 MB with no account, up to 3 tries a day. A free account keeps your transcripts in a library and lifts the guest limits; the current limits and paid plans are on the pricing page.
