audiogram.video
audiogram.video turns audio into a video made for social feeds. Open a podcast clip, an interview, an iPhone voice memo or a song (MP3, M4A, WAV, FLAC and more, or a video's sound), choose Square, Vertical, Portrait or Landscape, and drag the window on the timeline to the moment you want, up to 10 minutes per video. Seventeen templates are drawn live with your own title, cover art and words, and adding a cover re-colours the design to match it.
Captions are written out from the speech as soon as a recording opens and highlight each word as it is said; correct any line by typing over it and download SRT or VTT. For that step only the chosen clip's sound goes to a speech-recognition service, which keeps nothing, and the Automatic captions switch turns it off. The video itself is drawn and encoded in the browser and exported as an MP4 at 1080p or 720p, with no sign-up and no watermark.
