About AudioVizFree

AudioVizFree is a browser-based toolkit for music creators, podcast makers, and anyone who wants to give an audio file a visual form.

Visualizer videos and waveform images

Create an audio-reactive video with a spectrum, a title, and your artwork. Or make a static waveform image for a cover, a design, or an overlay. The editor provides twelve visual styles, three aspect ratios, and color, background, and text controls.

Processing happens on your device

Your browser reads the audio, analyzes its frequencies, draws the visual, and produces the download. Audio and images are not uploaded to an AudioVizFree media server. There is no account system in the editor and no watermark on exported files.

Supported formats and export limits

Video export depends on the recording formats supported by your browser. The export menu lists available formats. Recording happens in real time and is limited to clips of 5 minutes. Whole-track waveform images require audio up to 5 minutes and 25 MB.

AudioVizFree does not provide cloud rendering, automatic captions, or calibrated acoustic measurements. The tools focus on creating visuals from audio you already have.

Start with an original demo

The included “Sunset Drive” demo is a short synthesized track created for this site. It lets you test playback, templates, and exports without choosing a file. The visuals in the template library are style previews.
