Turn a podcast clip into a waveform video
Quick answer: the Podcast Audiogram Maker is designed to render an audiogram - your cover art with a moving waveform and optional captions - sized for 9:16, 1:1, 4:5 or 16:9. Rendering is a preview today; the Transcript and Subtitles modes below, sharing this same page, are live and work now.

Paste a direct link to an audio or video file, or a page a supported downloader can read.
Not every site is supported - private, paywalled or DRM-protected episodes can never be imported this way. If a link fails, download the episode yourself and use Upload File instead.
RSS import is planned so a whole show's feed can be browsed by episode, but it is not built yet. Use Upload File to try Transcript today.
You can keep this tab open and carry on - longer episodes take a few minutes. Refreshing the page reconnects to this job.

Smart Clips is a preview
Finds moments that could work as standalone clips - hooks, quotes, insights - with a start/end you can adjust. This mode has no working backend yet, so nothing is generated or uploaded when you select it - it will switch on here the moment it ships.
Reel Maker is a preview
Turns a clip into a captioned 9:16 vertical video with a waveform and safe-zone framing. This mode has no working backend yet, so nothing is generated or uploaded when you select it - it will switch on here the moment it ships.
Audiograms is a preview
A waveform video over your cover art, sized for the feed - no video footage required. This mode has no working backend yet, so nothing is generated or uploaded when you select it - it will switch on here the moment it ships.
Summary is a preview
A short and a detailed summary plus key takeaways, generated from the transcript. This mode has no working backend yet, so nothing is generated or uploaded when you select it - it will switch on here the moment it ships.
Show Notes is a preview
Chapters with timestamps, plus a starting point for links and guest details. This mode has no working backend yet, so nothing is generated or uploaded when you select it - it will switch on here the moment it ships.
Blog Article is a preview
Restructures the transcript into a readable article outline, not a raw paste of the text. This mode has no working backend yet, so nothing is generated or uploaded when you select it - it will switch on here the moment it ships.
Silence Remover is a preview
Finds and previews silent stretches so you can shorten them without cutting natural pauses. This mode has no working backend yet, so nothing is generated or uploaded when you select it - it will switch on here the moment it ships.
No generated assets yet
Once clips, Reels or audiograms can be rendered, finished files will appear here with format, size and expiry, downloadable one at a time or as a ZIP.
What an audiogram will look like
A static preview of the planned output - not a live renderer. Nothing here is generated from your file yet.
1:1 shown - 9:16, 4:5 and 16:9 will use the same layout system.
An audiogram is a video, not an audio file
Audiogram: a short video built from an audio clip - your cover art or a background image, a waveform that moves with the sound, a progress bar, and usually a caption line. It exists because video-first platforms - Instagram feeds, Twitter/X, LinkedIn - do not autoplay a bare MP3, but they do autoplay a video. Rendering an audiogram means producing a real MP4 file, not attaching a picture to an audio file or relabelling an MP3 as a video.
What this tool does
Once live, it will render a chosen clip as an MP4 waveform video over your cover art, at your chosen aspect ratio.
Accepted input
An uploaded audio or video file up to 500 MB, or a clip selected from Smart Clips once that mode ships.
Expected output
A downloadable MP4 file with a moving waveform, cover art, a progress bar and optional captions - not yet available to render or download.
How to use it, once it ships
Upload or pick a clip
Add your episode, or start from a clip Smart Clips has already found.
Choose a size
9:16 for Stories/Reels, 1:1 or 4:5 for feed posts, 16:9 for standard video.
Render and download
Get an MP4 with your cover art, waveform and captions already rendered in.
A realistic example
A 30-second key-insight clip becomes a 1:1 audiogram: the show's cover art dimmed slightly behind a bright waveform reacting to the guest's voice, the episode title and speaker name in the top corner, and a one-line caption tracking the audio - ready to post where a bare audio file would not play.
Common use cases
Podcasters
Promote a new episode on platforms that only autoplay video.
Marketing teams
Turn a quote into a shareable video without filming anything.
Guests
Share their own moment from the episode in a video-native format.
Music & audio creators
The same waveform-video approach works beyond podcasts, for any audio clip.
Limitations
- Not available to run yet - no MP4 can be rendered or downloaded.
- This page shows the intended layout only, not a live preview of your own audio.
- Caption accuracy will depend on transcript accuracy once captions are wired in.
Privacy and retention
- Files uploaded for Transcript or Subtitles today are held only long enough to transcribe them, then removed by routine cleanup.
- Nothing is uploaded for audiogram rendering specifically, since that mode does not yet exist.
- Only process content you own or have permission to use.

Frequently asked questions
Is the Podcast Audiogram Maker available to use right now?
Not yet. Audiogram rendering is shown as a preview; selecting Audiograms will not process your file. Transcript and Subtitles, on the same page, are live today.
What is an audiogram?
A short video built from an audio clip: your cover art or a background image, a moving waveform synced to the audio, and usually captions - a way to share audio on video-first platforms without filming anything.
Is an audiogram just the audio file with a picture?
No. The plan is to render a real video file (MP4) with a moving waveform, a progress bar and optional captions - not a static image with sound attached.
What sizes will be supported?
9:16 for Stories and Reels, 1:1 and 4:5 for feed posts, and 16:9 for standard video.
Can I download an MP4 today?
No. Rendering has not shipped, so there is no video to download yet - the preview above shows the intended layout only.
Does audiogram rendering work on my file today?
No. Only Transcript and Subtitles are connected to a working backend. Upload a file to get a timestamped transcript now; audiogram rendering will use that same upload once it ships.
