Make a podcast audiogram

Choose the episode, then pick the moment. Save your show’s look to reuse it.

A podcast audiogram is a short video of a moment from an episode: your cover art, a waveform that moves with the voices, the words on screen and a line telling people where to listen. Open the episode above, choose the moment, and the studio builds one in your show’s colours, ready for a feed, your website or LinkedIn.

The studio opens on Templates, where every design is drawn with your own cover and title. Once a look is right, save it under My styles and the next episode takes one click. If you are new to audiograms, how to make an audiogram that people stop for covers length, hooks and where to post.

How to make a podcast audiogram

  1. Open the episode

    Square is selected on the card. Press Choose an episode (Ctrl+O or ⌘+O) and pick the exported episode or a raw recording; MP3, WAV and M4A all work, and a video file gives up its sound. Long episodes open on their liveliest 30 seconds.

  2. Choose the moment

    Drag the window on the timeline under the preview, or open Audio and press Best 30 s or Best 60 s to jump to the busiest stretch of talking. The Clip start and Clip end handles fine-tune it, and arrow keys move them by a second.

  3. Add the show’s art and words

    In Text, add your Cover art, the episode in Title, the show or guest in Show or speaker, and a Tag line such as “Full episode out now”. The colours follow the cover.

  4. Make the captions

    In Captions, press Make captions. Only this clip’s sound is sent to our speech provider to be written out. Fix any word by typing over it, and choose Highlight so words light up as they’re spoken.

  5. Save the style and export

    In Templates, type a name under My styles and press Save. Then press Export, Export video and Download video.

A look you set up once

The slow part of audiograms is not the first one. It is making the twentieth look like the first. My styles in the Templates panel saves the current layout, colours, font, wave, caption style and your tag line under a name you choose.

  • Next episode: open the new recording, press your style’s name, add the new cover or title, and the rest is already in place.
  • Several shows, or a show plus a guest series? Save one style for each.
  • Styles are kept in this browser. Use the same browser on the same computer each week, or save the style again elsewhere.

Colours that follow the cover

When you add Cover art, the studio takes its main colours for the background, the wave and the highlighted words. If you change the artwork for a special episode, the design re-colours itself; press undo to go back. Match cover art in Style re-applies the cover’s colours after you have experimented.

Templates that work for shows

  • Night show: cover art over a soft glow with a mirrored wave and word-by-word captions. The safe default for talk shows.
  • Newsroom: crisp white with a strong headline and a lower third for the speaker. Suits news, business and interview shows, and reads well on LinkedIn.
  • Split: the cover fills one half and the words the other, ideal in landscape for a website or YouTube community post.
  • Paper and Notebook: warm, quieter looks for storytelling, wellbeing and book shows.
  • Terminal: monospace type and a green scope line for tech podcasts.
  • Halo: a round cover with the voice pulsing in a ring around it.

The shape is chosen separately from the template, so the same moment can go out as a square post and a vertical clip for Reels, TikTok and Shorts without starting over: change the shape in Templates and export again.

Captions for two voices, and the words you got wrong

Most people scroll with the sound off, so the captions do the work. Make captions writes out the clip and times every word. It doesn’t label who is speaking, so if a guest answers a question, put their name in Show or speaker or keep the clip to one voice.

  • Names, brands and jargon are where speech recognition slips. Read the cues in the Captions panel and type over anything wrong.
  • Pick the Language if the show isn’t in English and the detection picks wrongly. Twenty-four languages are listed.
  • Already have a transcript? Press Open SRT or VTT, or paste the words and press Use this text (the timing is then spread evenly, so it is approximate).
  • Need the captions as a file for YouTube or a website? Download SRT or VTT from the same panel. The audio to SRT page explains the two formats.

Your episode file never leaves your device. Pressing Make captions is the one exception: it sends the selected clip’s sound, compressed, to our speech-recognition provider, which writes it out and keeps nothing.

Where podcast audiograms go

  • LinkedIn, X and Facebook feeds: square (1:1) at 1080p. X accepts videos up to 2 minutes 20 seconds on a standard account, so 30 to 90 seconds is a good target.
  • Instagram feed: Portrait (4:5) fills more of the phone screen.
  • Your website or newsletter: square or landscape, set to play muted with the captions on.
  • YouTube: landscape works as a trailer; the podcast on YouTube guide covers full episodes.

Podcast audiograms: common questions

What is a podcast visualizer?

It is the same idea as a podcast audiogram: a video that shows the sound moving, usually as a waveform beside the cover art, so audio can be posted where only video is allowed. The Wave panel has nine styles, from bars and rings to a calm seek bar.

Can I make podcast audiograms for free?

Yes. There is no plan to buy, no watermark on the video and no account. Each audiogram can be up to 10 minutes long.

How do I turn a whole podcast episode into a video?

Each video made here holds up to 10 minutes, so it suits trailers and highlights rather than hour-long episodes. For a full episode on YouTube, see the options in the podcast on YouTube guide.

Can it pick the best moment for me?

Best 15 s, Best 30 s and Best 60 s in the Audio panel find the liveliest stretch of talking, which is a good place to start. They measure energy, not meaning, so listen and move the window to the line you actually want.

What size should podcast cover art be?

Apple Podcasts asks for square artwork between 1400×1400 and 3000×3000 pixels, as a JPEG or PNG. That same file is ideal here: it stays sharp in every format at 1080p.

Will the style I save be there next week?

Yes, if you use the same browser on the same device. Styles are stored in the browser, not in an account, so clearing site data removes them.

Does it work with video podcasts?

You can open a video file, but only its sound is used: the picture becomes your cover art, wave and captions. It is made for audio shows, or for giving a video show’s audio a clean, captioned look.
