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

Our Audio Waveform Visualizer can show you a video illustration of your audio files and help you identify signal strength, also known as amplitude — a "visual sound video". In other words, it allows you to "see" your audio files. Please note that large files can take a few minutes to process. The video files it produces can be quite large.

Why do I need to use a waveform visualizer?

You can learn a lot about the structure of your audio files by viewing the output in visual form. A waveform visualizer allows you to check the amplitude changes in your tracks. On another level, it produces a dynamic video which can be used as a background video for your track.

What information is shown in the Visualizer video?

The Visualizer Video shows the waveforms in an audio file, which illustrate the changes in a sound's amplitude over time. Amplitude measures the relative strength of sound vibrations in music.
