Audiogram generator FAQ

What is an audiogram?

An audiogram is a short video that pairs an audio clip with an animated waveform and an optional caption. It turns sound-only content like a podcast audiogram or music snippet into motion, which performs far better than a static image in social feeds.

Is my audio uploaded to a server?

No. This tool runs entirely client-side using the Web Audio and MediaRecorder APIs built into your browser. Your audio files and background images never leave your device and are never uploaded to DominateTools.

What formats can I export?

Upload MP3, WAV or OGG audio, then export a WebM/MP4 video with your chosen waveform. You can render at square 1:1, vertical 9:16 or wide 16:9 dimensions.

Which aspect ratio should I use for TikTok, Reels and YouTube?

Use 9:16 for TikTok, Instagram Reels and YouTube Shorts, 1:1 for Instagram or X feed posts, and 16:9 for standard YouTube and LinkedIn video.

Turn audio into video that actually gets watched

Sound-only posts struggle in feeds built for motion. Instagram, TikTok, X and LinkedIn all favour video, so a plain audio share tends to stall. Converting a clip into an audiogram — a video with a moving waveform — gives the algorithm the motion it rewards and gives viewers a reason to stop scrolling. It is one of the simplest ways to repurpose a podcast episode, a quote, or a music teaser into something shareable.

A free audiogram maker built for podcasters

Most audiogram tools gate high-resolution exports behind a monthly subscription and stamp watermarks on free renders. This audiogram maker leans on modern browser APIs to do everything locally, so you get clean, unwatermarked video at no cost. Drop in a background image and a bold caption to create a branded podcast audiogram, then reuse the same clip across every platform.

How to make an audio waveform video

Step 1: Prepare a short MP3 or WAV clip — under 60 seconds works best for social.

Step 2: Upload the audio using the panel on the left.

Step 3: Pick an aspect ratio — 9:16 fits TikTok, Reels and Shorts.

Step 4: Choose a waveform style and colour, then add an optional background and title.

Step 5: Press play to preview, then click Render & download video to save a platform-ready file.

Who uses audiograms?

Podcasters clip the best 30 seconds of an episode to tease it on social. Musicians preview an unreleased track with a visualizer. Marketers and course creators pull memorable quotes from webinars and interviews. Because the audiogram generator runs in your browser, sensitive or unreleased audio never leaves your machine — making it a safe way to turn audio into video before anything is public.
