Make an audiogram for your podcast

Turn your best minute into a video people watch.

Pick the best moment of an episode and Onda turns it into a video: your cover art, an animated waveform and captions that follow the voice, sized for vertical feeds, square posts or a widescreen player.

How it works

  1. Choose the moment

    Upload an episode or paste your RSS feed, then select a clip of up to 3 minutes, or let Onda suggest the most quotable moments.

  2. Design the video

    Pick a format (9:16, 1:1 or 16:9), a waveform style and your colors. Cover art and captions are added automatically.

  3. Export the MP4

    Download a 1080p MP4 with the captions burned in, ready to post.

Why use it

  • Audio that stops the scroll

    A still cover with a play button is easy to skip. Motion and captions give people a reason to watch the first seconds.

  • Clip suggestions

    Onda flags the moments with strong quotes or reactions, so you don’t have to scrub through an hour of audio to find them.

  • On brand every time

    Save your fonts, colors and layout as a template, and every clip of the season looks like it belongs to the same show.

Questions and answers

What is an audiogram?

A short video made from an audio clip, usually with the show’s artwork, a moving waveform and captions. It lets you share a podcast moment on platforms built for video.

Which format should I pick?

9:16 for vertical feeds and stories, 1:1 for square posts and 16:9 for video platforms and websites. You can export the same clip in all three.

How long should a clip be?

Between 30 and 90 seconds suits most feeds: long enough for a complete thought, short enough to be watched to the end. The maximum is 3 minutes.

Can I use a video instead of cover art?

Yes. Upload an image or a short looping video as the background; the waveform and captions are layered on top.
