What Is An Audiogram?

An audiogram is the combination of audio, video, and graphic assets to create a short-form video. Generally, audiograms include a transcription of the video’s scripted portions and a moving sound wave graphic as it plays.

Audiograms can highlight an interesting soundbite from an interview or segment to give followers a taste of what the full episode is all about. They’re the perfect way to prepare listeners for upcoming episodes and entice them to tune in immediately after the episode drops.

How To Make A Podcast Video Using the Headliner App

To get started with the Headliner app, all you need is an audio clip ready to go. From there, use the platform’s drag-and-drop editor to add graphics, captions, and more. In the end, you’ll have a unique video asset perfect for any social channel you choose.

Here’s how it works, step by step.

Castos is now integrated with Headliner. All Growth and Pro plan members can create audiograms and the final video asset will automatically sync with your Castos dashboard. See how Castos and Headliner work together.

1. Upload an audio file or connect your podcast’s RSS feed

Headliner makes it easy to get started. All you have to do is either upload an audio clip or connect your podcast’s RSS feed and you show will appear.

When connecting an RSS feed, click on your podcast’s name and select the episode you want to create an audiogram for. For uploads, the file needs to be in a MP3 or WAV format and under 500MB.

Alternatively, add your podcast’s RSS feed to automatically import episodes.

2. Trim the audio clip

Each social media platform has a restriction on the length of video clips. But no need to head to Google to figure it out. Headliner’s editor includes a “Time Limit Selector” that automatically adjusts the clip duration to each platform’s maximum time limit.

Decide on the social channel and move the blue window to the part of the clip you want to share.

3. Choose the aspect ratio

Similar to differences in duration, every social platform has a preferred aspect ratio for video posts. Choose between landscape, portrait, or square and Headliner will tell you which channel is best for that size. If you plan to use your podcast cover art for the background image, choose the 1:1 aspect ratio (the square).

4. Make basic edits

Next, customize the audiogram by adding text, changing the color, location, size, and look of the waveform, or update the background image. These are the basic customizations to your audiogram so you don’t need to spend a lot of time here. The next step takes you to the drag-and-drop editor for more advanced tweaks.
