Short answer

To make a podcast audiogram, pick a 30 to 60 second moment that stands alone, clean the audio, and build a 9:16 layout: cover art at the top, a simple waveform in the middle, big captions below. Add the show name, a hook line in the first 3 seconds and an end card saying where to listen.

Anatomy of a podcast audiogram

An audiogram has one job: make people read along with a voice they cannot see. The captions matter most, then the waveform, then everything else.

PartWhat it looks likeHow to ask for it
Cover artYour show art, large, near the top"show cover art at the top"
WaveformBars or a line reacting to the voice"a white waveform reacting to the voice"
CaptionsLarge, a few words at a time, high contrast"big captions, a few words at a time"
LabelsShow name, episode, speaker name"show name and episode number above the waveform"
ColourYour brand colours, one accent for key words"brand navy background, key words in yellow"
EndingWhere to listen, a short line"end on: listen to the full episode"

Worked example: a 45 second audiogram from a solo episode

An illustration, not a real show. The episode is a 40 minute solo podcast about personal finance, and the chosen moment is a short story about a first budget, which makes sense without the rest of the episode.

TimeOn screenAudio
0 to 3 sHook headline: "I tracked every coffee for a year"The line itself, pulled from 0:31 of the clip
3 to 20 sCover art, waveform, captions three to four words at a timeThe setup of the story
20 to 35 sA small icon of a receipt appears with the number on screenThe surprising total
35 to 42 sKey words in the accent colourThe lesson in one sentence
42 to 45 sEnd card: show name, "full episode on all podcast apps"Music tail

At a normal talking pace of about 150 words a minute, 45 seconds is roughly 110 words, which works out to around 30 caption screens of three to four words. That is why caption size and timing matter more than any visual flourish.

How to make a podcast audiogram in 6 steps

  1. Bring the audio. Upload the episode file or paste a YouTube link to the episode.
  2. Pick the moment. Ask Otto to find the strongest 30 to 60 seconds, or give the start and end time you want. It has to make sense to someone who has never heard the show and start on the interesting part, not the lead in.
  3. Clean the sound. If the recording has noise or echo, ask for it to be cleaned first. Bad audio is the fastest way to lose a listener.
  4. Choose the layout. Cover art on top, waveform in the middle, captions below is the classic 9:16 layout. Keep captions above the bottom 15% of the frame, where app buttons sit.
  5. Style the captions. Big, three to five words at a time, key words in your accent colour.
  6. Add the end card. Show name and where to listen, held for 2 to 3 seconds.

If you do have video of the episode, a normal clip with the speaker on screen usually beats an audiogram. Audiograms shine for audio only shows, phone interviews and voice notes.

Shorter audiogram prompts

  • "Turn this voice note into a video with a waveform and captions."
  • "Make five audiograms from this episode, each a different topic."
  • "Use a round waveform around the cover art."
  • "Show the speaker's name when they start talking."

Audiogram sizes, lengths and tools

Post the same moment in more than one shape if your audience is spread across platforms.

WhereAspectResolutionGood length
TikTok, Reels, Shorts9:161080x192030 to 60 seconds
Instagram or Facebook feed4:5 or 1:11080x1350 or 1080x108030 to 60 seconds
LinkedIn1:11080x108030 to 90 seconds
X1:1 or 16:91080x1080 or 1920x108030 to 60 seconds

Dedicated audiogram tools such as Headliner, and editors such as Descript or Canva, all make this format with templates. Built by hand in a general editor like Premiere Pro, one 45 second audiogram with timed captions typically takes 30 to 60 minutes, mostly on caption timing. With Otto it is a first draft from the prompt plus a few minutes of changes, and asking for five clips from one episode is the same request with a different number.

A few extras make an audiogram feel like a real video: a small photo of whoever is speaking that switches with the speaker, an icon or number that appears on a key point, and a slow push in on the cover art.

Audiogram mistakes that lose listeners

  • Small captions. The words are the content. On a phone, captions should be readable at arm's length.
  • A busy waveform. A loud, jumpy meter distracts from the words. A thin line or a few soft bars is enough.
  • A clip with no point. A great line in a plain audiogram beats a weak line in a beautiful one. Pick a moment that lands on its own.
  • No call to action. Tell people where to find the full episode, by show name, not a URL nobody can tap.

FAQ

What is an audiogram for a podcast?

An audiogram for a podcast is a short video made from an audio clip, usually showing the show's cover art, an animated waveform that moves with the voice and captions of the words being said. It lets audio only podcasts post clips on video first platforms like Instagram, TikTok and LinkedIn, where a plain audio file cannot be shared.

Do audiograms still work on social media?

Audiograms still work on social media when the moment is strong and the captions are large, but they compete with full video clips, which usually hold attention better. If your show records video, post clips of the speakers. If it is audio only, an audiogram is the practical way to share moments, and the line you choose matters more than the design.

What is the best length for a podcast audiogram?

The best length for a podcast audiogram is usually 30 to 60 seconds: long enough for one complete idea, short enough that people finish it. Under 20 seconds rarely gives a story room to land. Longer clips can work on LinkedIn or YouTube, but only when the moment holds attention all the way through.

How do I make an audiogram for free?

You can make an audiogram for free with the free tiers of tools like Headliner or Canva, which offer waveform templates, though free plans often limit exports or add a watermark. A manual option is a free editor such as CapCut or DaVinci Resolve, with a waveform effect and auto captions, at the cost of more setup time.

Should I use a waveform or captions in an audiogram?

You should use both in an audiogram, but captions matter far more than the waveform. Many people watch with the sound off, so the captions carry the words, while the waveform simply shows that audio is playing. If space is tight on a small screen, shrink the waveform and keep the captions large.
