Online Audiogram & Waveform Video Generator

Turn your static audio files into dynamic, shareable MP4 videos with animated sound visualizers effortlessly.

What is an Audiogram?

An audiogram is a highly engaging short video that combines a static background image, an animated audio waveform (visualizer), and the sound file itself. Since social media platforms like Instagram, TikTok, and YouTube do not allow users to upload plain audio files (like MP3 or WAV), our free online audio to video converter bridges this gap. It helps you instantly convert audio to video right in your browser, maintaining 100% data privacy.

How to create a waveform video?

First, select your audio file and upload a high-quality background image (aspect ratios like 9:16 for Reels or 1:1 for posts work best). Next, use our intuitive customization panel to adjust the waveform's color, position, and thickness to match your brand's aesthetic. You can preview the animation in real-time. Once you are satisfied with the design, click export to render and download a watermark-free .mp4 file directly to your device.

Who uses this tool?

This free online audio visualizer is heavily used by podcasters to share episode highlights on social media, musicians and beatmakers promoting their original songs and royalty-free tracks, and content creators turning their personal voice memos into engaging visual content for their audience.

Yes. The Audiogram Maker is completely free, requires no signup, and has no daily limits. You can generate as many videos as you need.

Are my audio files safe and private?
Absolutely. All audio processing and video rendering are performed locally within your web browser's memory. Your private files are never uploaded to any external servers.

No. The Audiogram Maker works entirely online directly within your web browser, removing the need to install or download heavy video editing software like Premiere or Final Cut.

How long does it take to render?
Rendering time depends on your device's processing power and the length of your audio file. Since it uses your browser's local resources, keeping the browser tab active during export speeds up the process.
