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

Our Audio Channel Visualizer can show you a video illustration of your audio files and help you identify the channels 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 a channel visualizer?

You can learn a lot about the structure of your audio files by viewing the output in visual form. A channel visualizer allows you to check the stereo depth of your tracks and see clearly how similar or different your left and right channels are. On a simpler level, it produces a vibrant video which can be used as a visual background for your track.

What information is shown in the Visualizer video?

The Visualizer Video shows a Vectorscope, which illustrates the separation of stereo channels in an audio file. The wider your stereo image, the more variation exists between left and right channels. Mono recordings will only show a single vertical line because there is no left/right stereo separation.
