Make a podcast audiogram people stop for

Add the audio from your episode and your cover art. The waveform moves with the voice, and you download an MP4 ready to post.

How it works

  1. Step 1

    Cut the clip first

    Trim your episode to the part you want posted before you add it here. This page draws the waveform, it does not choose the moment.

  2. Step 2

    Add the audio and your cover art

    MP3, WAV or M4A up to 250 MB and 10 minutes. The image can be your show cover or a photo of the guest.

  3. Step 3

    Pick the shape and download

    9:16 for Reels, Shorts and TikTok, 1:1 for a feed post, 16:9 for YouTube. The video is made on your device.

What makes an audiogram worth watching

  • One self contained thought. A clip that needs the previous two minutes to make sense loses people in the first second.
  • Start on the sentence, not on the breath before it. Silence at the front reads as a broken file.
  • Short enough to finish. A clip someone watches to the end is worth more than a longer one they leave.
  • Readable at a glance. Cover art with small type becomes unreadable at phone size, so a plain image with a face or a logo holds up better.

Cover art, a photo, or no picture at all

PictureWhat people seeWhen to use it
Cover art and waveformYour show artwork with the waveform moving near the bottomEpisode clips posted to your own feed, where the artwork is the brand
A photo and waveformA photo of the host or guest with the waveform over itA guest episode, where the face is the reason to listen
Waveform onlyA white waveform on blackA quick quote clip when there is no artwork to hand

Want the host on screen instead of a waveform?

A waveform shows that sound is happening. A face speaking holds attention differently, because people watch people. Audio driven lip sync animates a photo of your host to this same audio file, so the clip you just made can become the host saying it.

Make the host speak on screen

Animate one photo to your audio file with lip sync, at 2 credits a second, so a 30 second clip is 60 credits.

Frequently asked questions

Everything you need to know before you start.

A short video made from audio, usually your cover art or a photo with a waveform moving over it, so a podcast clip can be posted on platforms that only take video.

Add the audio clip and an image on this page, choose cover art and waveform, pick a shape and download the MP4. It runs in your browser, so there is no sign up and no watermark.

Choose 9:16 for Reels, Shorts and TikTok, 1:1 for a square feed post, and 16:9 for YouTube.

Yes. Choose Waveform only and the video shows a moving white waveform on black for the length of the audio, with no image needed.

The waveform is drawn frame by frame on your device, so a few minutes of audio can take a few minutes. Trimming the clip before you add it is the fastest way to keep it quick.

No. The audio and the image are processed on your device with FFmpeg running in WebAssembly, and nothing is sent to us.
