How to Visualize Audio Waveforms
Upload any audio file. The Web Audio API decodes it and extracts amplitude peaks from each channel. The Canvas API renders the waveform visualization. Choose a color theme and export as PNG for use in thumbnails or presentations.
Frequently Asked Questions
Can I see both stereo channels?
Yes. The viewer shows Left and Right channels separately for stereo files, or a single channel for mono audio.
Can I zoom in on specific sections?
Yes. Use the zoom slider or scroll wheel on the waveform to zoom in for millisecond-level detail.
Can I export the waveform as an image?
Yes. Click Export PNG to download the waveform visualization as a high-resolution PNG image.
What color themes are available?
Violet (default), Emerald, Amber, and Neon. Each changes both the waveform color and background.
Is my audio file uploaded?
No. The Web Audio API decodes your file locally and the Canvas API renders the waveform. Nothing is uploaded.
