Audiogram Maker for Podcasts

Turn a podcast moment into a short video with a moving waveform and captions. Upload an episode, interview or talk. This audiogram maker picks a moment of up to 90 seconds. Export an MP4 for social media.

Pick the episode, then the moment

Before you make an audiogram, decide the clip's job: tease an episode, quote a guest or share a lesson.

Episode teasers

Pick the line that makes people want the rest. Skip the intro and the sponsor read. One idea fits one clip.

Guest quotes

Choose a moment where the guest is specific: a number, a story or a clear opinion. Add the guest's name so the clip works alone.

Lectures and readings

Ask for one full explanation or one passage. A summary of the whole recording does not fit in 90 seconds.

How to make an audiogram

Three steps in the audiogram maker above. You approve the moment before anything is exported.

  1. 1. Upload the episode

    Upload the episode as MP3, WAV or M4A. Add a cover image and say who the clip is for.

  2. 2. Approve the moment

    Potto lists where the moment starts and ends. Approve it, or name another moment.

  3. 3. Check, then export

    Check the waveform and the captions. Export the MP4, and download the SRT if you need it.

What the audiogram maker does

An audiogram maker should not make you trim audio by hand. Potto's audiogram maker reads your episode and proposes the moment. It then builds the audiogram around it.

  1. 01

    One moment from your episode

    Tell Potto what the clip is for. It proposes one continuous moment. Name a different one if it misses.

    A waveform that follows the voice

    Bars, a wave or a ring move with the speech. Viewers see someone talking even with the sound off.

Audiogram FAQs

Definitions, audio types, limits, captions, styles and credits.

  1. What is an audiogram in podcasting?

    An audiogram is a short video that plays audio over a moving waveform, usually with captions. Podcasters post one to preview an episode in a feed. Outside podcasting, doctors use the word for a hearing test chart. This page covers the video kind.

  2. What is an audiogram maker?

    An audiogram maker turns audio into a waveform video. Most make you trim the clip first. Potto's audiogram maker proposes the moment for you. Use it to make an audiogram of any episode, then export an MP4.

  3. What is a podcast audiogram?

    A podcast audiogram is an audiogram made from one moment of an episode. It shows the show name, the speaker and the cover art. Viewers can read the captions with the sound off. Its job is to make people press play on the full episode.

  4. How do I use the audiogram maker?

    To make an audiogram, drop your audio into the creator at the top. Describe the audience and the moment you want. Potto proposes a start and an end in chat. Approve them or name another moment. After a preview, export the MP4.

  5. How does the audiogram maker pick a moment?

    This audiogram generator reads a transcript of your file. If you name a moment, it uses that one. If you do not, it proposes a moment and may skip an intro or an ad. You confirm the times in chat. There is no timeline picker.

  6. What audio works best in an audiogram maker?

    Clear speech does. Interviews, solo episodes, panels, lectures and readings all work. Captions follow the words, so little background noise means fewer mistakes. Pick a moment with one clear idea.

  7. How long can the audio and the audiogram be?

    Files can run 10 minutes and 20 MB. The accepted types are MP3, WAV and M4A. The audiogram itself is one clip of up to 90 seconds. A longer episode needs trimming first.

  8. Can I put my show name, guest and cover art on the audiogram?

    Yes. Upload a cover image with the audio. Give the episode title, the show name and the guest in your message. They appear next to the waveform. Potto shows only the details you give it.

  9. Does the audiogram maker add captions?

    Your audiogram gets captions without extra steps. They come from the transcript of your clip. Get the SRT file for a player that takes caption files. Misheard words are common with names, terms and numbers, so read every line.

  10. What waveform styles does the audiogram maker offer?

    Choose bars, wave or ring. Without a request you get bars. The wave suits quiet interviews. The ring sits around your cover art. One style runs through the whole audiogram.

  11. What sizes can the audiogram maker export?

    Potto exports a 1080p MP4 at 30 fps. Square 1:1 is the default for feeds. Use 9:16 for Reels, Shorts and TikTok. Use 16:9 for an episode page.

  12. Can I make an audiogram from a video podcast?

    Not from the video itself. Potto does not accept existing video files. Upload the episode's audio file instead. The result is a new waveform video, not an edit of your footage.

  13. What does the audiogram maker cost?

    Previews are free. Export costs 5 credits per second of video. A 60-second audiogram costs 300 credits. Sign-up gives you 100 credits, enough for a 15-second one. There is no voiceover fee. Your recording supplies the sound.
