How do I generate an audio waveform image from sound?

Upload your audio file, customize waveform visual style (Bars, Line, Mirror, or Wave), choose color palette and resolution (1920x1080, 1080x1080), and click 'Download Waveform' (PNG/SVG).

Can I export transparent PNG waveforms for music videos and podcast covers?

Yes. Enable the 'Transparent Background' toggle to export clean waveform overlays for video editors like Premiere Pro, After Effects, and Final Cut.

Can I customize bar width and spacing?

Yes. Adjust bar density, gap width, corner roundness, and gradient colors.

Can I export vector SVG waveforms?

Yes. Export scalable vector SVG graphics for print artwork or website integration.

Does the generator analyze full song dynamic range?

Yes. Calculates exact RMS and peak amplitude envelopes across the entire audio duration.

Is audio analyzed locally?

Yes. Decoded directly in browser Web Audio API memory.
