Free Online Audio File Visualizer
Quick & easy video visualizer for your audio files

Maztr's free online Audio File Visualizer is a quick and easy tool you can use right in your browser, without downloading any software, to visualize the sound structure of your audio files. No account or login is required to use it.

Our Audio File Visualizer can show you a video illustration of your audio files and help you identify the sound waves, channels and frequencies they contain — a "visual sound video". In other words, it allows you to "see" your audio files. Please note that large files can take a little time to process. The video files it produces can be quite big.

Why do I need to use an audio visualizer?

You can learn a lot about the structure of your audio files by viewing the output in visual form. Also, if you are uploading music to a video service such as Youtube, it allows you to add visual content that enhances the audio, rather than attaching a static image.
