About This Tool
Generate high-resolution vector audio waveforms and soundwave graphics directly from audio tracks or your microphone. This visualizer decodes audio files locally using the HTML5 Web Audio API, extracting peak amplitudes across frequency blocks without transmitting any audio bytes across the network.
Choose from multiple visual aesthetics including vertical bar equalizers, symmetrical mirror reflections, continuous bezier wave fills, and circular radial soundbursts. Export your finished soundwave directly as an SVG vector or transparent PNG image for podcast artwork, music covers, and video lower-thirds.
Key Features
- Zero server uploads: Decodes MP3, WAV, FLAC, M4A, and OGG files entirely inside browser memory using Web Audio AudioContext.
- Live microphone recording: Capture your voice or ambient audio in real time to generate unique custom soundwaves.
- Four visualization styles: Switch between center bars, symmetrical mirror waves, continuous organic curves, and circular radial burst diagrams.
- Curated color palettes: Apply calibrated gradients including Neon Cyan, Sunset Violet, Matrix Emerald, Amber Fire, and Minimal Slate.
- Lossless SVG & PNG export: Download infinitely scalable vector SVG files or rasterized high-resolution PNG images with one click.
Frequently Asked Questions
Are my audio files or voice recordings uploaded to your servers?
No. The audio decoding and waveform synthesis execute exclusively inside your local browser tab via the Web Audio API. Audio bytes never leave your device.
Which audio formats can I visualize?
Any format supported by your modern browser, including MP3, WAV, OGG, M4A, AAC, and FLAC files. You can also record voice clips directly using your microphone.
Can I use the exported SVG for commercial projects or podcast artwork?
Yes. The exported SVG and PNG graphics are completely open and free for both personal and commercial use without attribution requirements.
What is the benefit of exporting as SVG over standard PNG?
SVGs are mathematical vector paths that scale to billboard resolutions without pixelation, whereas PNGs have fixed pixel dimensions.
