Audiogram is a library for generating shareable videos from audio clips.
Here are some examples of the audiograms it creates:
Unlike audio, video is a first-class citizen of social media. It's easy to embed, share, autoplay, or play in a feed, and the major services are likely to improve their video experiences further over time.
Our solution to this problem at WNYC was this library. Given a piece of audio we want to share on social media, we can generate a video with that audio and some basic accompanying visuals: a waveform of the audio, a theme for the show it comes from, and a caption.
For more on the backstory behind audiograms, read this post.
First, read What kind of Audiogram setup do I want?.
Then, install Audiogram using the full installation instructions.
Once you've successfully installed everything, open a Terminal/command prompt, go to the directory you installed Audiogram into, and run the server with:
> npm start
Now you can open the Audiogram editor in a web browser. If you're running it on your local computer, it should be at
If you want to use a different port number, you can supply it in the command. For example, to use port 9999:
> npm start -- 9999
When you first open the editor in your browser, you need to choose an audio file. This should be a
.wav file (some other audio formats will probably work, but no promises).
You'll see a preview of your audiogram at the bottom. You can select a theme from the dropdown menu.
You can also add a caption. A caption will automatically wrap onto multiple lines, but if you want to force a line break you can put in multiple consecutive spaces. Right now you can only assign one caption to a video, but multiple/more automatic captions are in the works.
Below the preview, there is a tiny audio editor. If you only want to use part of your audio, not the whole thing, you can click and drag to select a portion of the audio. To hear the portion you've selected, you can use the controls at the bottom or use the space bar to play/pause (except in Safari, for some reason).
When you're ready to get your video, click "Generate." You may have to wait up to a a minute or two for this process to finish, but the page will give you status updates along the way. When it's done, you can view the video or download it with the "Download" button.
Audiogram defines the visual details like dimensions, colors, and spacing using "themes." This repo includes a few basic themes meant to give you a sense of what's possible, but you'll probably want to make your own. This will allow you to use your own colors and logos and fonts, or choose other dimensions (e.g. vertical video). For details, read more about Audiogram themes.
This project is a work in progress. If you have ideas or run into problems, open an issue! Better captioning is a high priority. Here are some possible future improvements:
Ultimately we had a few priorities in how we set this up, knowing that we would produce a lot of these under a variety of NYPR brands. We wanted to keep it simple, and we wanted a visual that strongly implies "AUDIO" to encourage people to unmute. As an added enhancement, the first and last frames of the video automatically use the "peakiest" frame from the entire thing so that it's a little more obvious in a thumbnail. If you want something other than the built-in waveform patterns, like dots or dancing emoji, there are some notes about how to go a different direction in the Developer notes.
