How to Make Audio Waveforms for Your Podcast

Podcasts are carving out a significant portion of the consumer media diet in 2020 and creators around the world are hungry to take part in the audio revolution. A 2019 study from Edison Research found that 32% of Americans age 12 and older listen to at least one podcast a month with overall listenership up 122% since 2014.

With thousands of shows entering an already crowded market, the onus is on podcast hosts and creators to find new and innovative techniques to break through the literal noise. Major platforms like Spotify and Apple Podcasts offer some discovery tools for smaller podcasts, but using social media to highlight memorable pod moments is still the best way to attract new listeners to what you're putting down.

There are few options for posting high quality audio content on Facebook, Twitter, Instagram, or LinkedIn at this point and that's where Audio Waveforms come in. Audio Waveforms are video representations of audio that use a simple animation to show frequency and amplitude over time. The waveform bounces and flows with the natural sound of your voice bringing a new visual flourish to audio content. Here's how to make an audiogram to share your podcast on social media:

  1. Open the Audio Waveform Tool in Kapwing

2. Upload your audio file and create a waveform

3. Add additional visuals to your video

4. Export Your Video and Share

Step 1: Open the Audio Waveform Tool in Kapwing

Ready to promote your podcast? Start by heading to the Audio Waveform tool in Kapwing. Click Get Started to head straight into the studio where you'll have all the tools you need to make the perfect Audio Waveform video. Kapwing is totally free to use with no watermarks as long as you sign in.

Step 2: Upload Your Audio and Create a Waveform

From inside the Kapwing Studio, click the "Audio" tab to upload the music that you want to make a waveform with. You can also record a podcast from directly within the product.

The audio file will upload directly and appear on the Kapwing timeline. If you have the MP3 or M4a file on your computer, you can drag and drop it to upload it to the timeline instead.

Don't stress about your clip being the perfect length before uploading. You can always trim the audio down later even after the audio waveform is generated in Kapwing. Creators can also adjust the volume of their audio, change the speed, and add audio effects like "Fade." You can also combine multiple audio tracks if you want to edit your podcast by adding an intro, an ad, or a sound effect.

Now it's time to add the waveform. There are multiple ways to convert the audio to a waveform element within Kapwing. The easiest option is to select the MP3 layer in the timeline and use the "Convert to waveform" button in the side panel.

Alternatively, you can click the "Elements" tab to select dynamic elements for your video. Find the option to "Add a Waveform" and select the layer that you want to use for the audiogram.

You'll immediately see an audio waveform appear in the canvas.

There are two waveform styles you can choose in Kapwing (bars and waves) and the audio waveform color can also be changed to anything you want using the customization bar on the right side of the screen.

Step 3:  Add Additional Visuals to your video

With your audio waveform created - you're ready to build out the other visuals that will complete your promotional post. You can upload additional images like your podcast cover art or photos of the hosts into your video to provide additional context and give viewers an idea of who they are listening to. Use the Images button to quickly search for logos of the podcast platforms where listeners can expect to find your show.

The Text tool is also a great way to add more information to your video. You can add the title of an episode you're featuring or a URL where your followers can go to listen to more episodes. Kapwing makes it easy to rearrange all of the layers on your canvas so that your waveform be placed anywhere in the frame.

Step 4: Export Your Video and Share

Watch your video a few times to make sure that the clip is exactly what you wanted and the audio waveform looks good. If everything is in order, then you are ready to export. Click the red Export button in the top right corner of the screen to process your video for downloading.

You can download your video or instantly share it to social media once Kapwing is done processing.

Your audio waveform video will publish in just a few minutes with no watermark as long as you are signed into Kapwing. Once this process is finished you can instantly download your video or use the provided social links to instantly share it online.
