A podcast audiogram is a short video clip with an animated waveform synced to your audio, often with captions for accessibility. Podcasters use audiograms to promote episodes on social media platforms like Instagram, TikTok, and LinkedIn. Unlike a static image post, an audiogram catches the eye with movement and gives followers a taste of the episode. They're one of the simplest ways to turn audio content into something people actually stop scrolling to watch.
Different platforms favor different dimensions. Square (1080×1080) works on Instagram feeds and Twitter. Portrait (1080×1920) is best for Instagram Stories, TikTok, and YouTube Shorts. Landscape (1920×1080) fits YouTube and LinkedIn posts. This tool lets you switch between all three with one click, so you can export the same audio clip in every format you need.
Most audiogram tools upload your audio to a server for processing. This tool does everything in your browser using the Web Audio API and WebCodecs. That means your audio never leaves your computer, there’s no file size limit, no waiting in a queue, and no watermarks. It’s faster, more private, and completely free.
Now automate your full episode editing. WizCut switches cameras based on who’s speaking — so you spend less time in the timeline.
