Soundwave Art Maker — Posters & 3D Prints

Turn a song, a voice message or a first dance into soundwave art. Make a print-ready poster (PNG or SVG), or a 3D-printable soundwave keychain or plaque (STL). Free, in your browser — your audio is never uploaded.

Your waveform updates as you change the settings.

How it works

  1. Add your audioA song, a wedding vow, a baby's first laugh, a voice message from someone you love. Pick the part that matters most.
  2. Design itChoose bars, a filled wave, dots or a circle, a colour palette and your words. Sizes are ready for A4, A3, square frames and wallpapers.
  3. Print itDownload a 300 dpi PNG or an SVG for any print size, or switch to 3D and download an STL keychain or plaque for your 3D printer.

Ideas

Wedding & anniversaryYour first-dance song or vows as a framed print, with names and the date underneath.
A voice to keep“I love you” from a voicemail, a child's first words, or a laugh — as a keychain you can carry.
For musiciansYour single's waveform as merch: posters, stickers (use the SVG) or 3D-printed plaques.
Laser cutting & vinylThe SVG is clean vector art, ready for Cricut, Silhouette or laser cutters.

FAQ

Is the waveform really from my audio?

Yes. Each bar is the loudness of that slice of your recording, so the shape is unique to it. Until you add a file, a sample wave is shown.

What size can I print?

PNGs are 300 dpi at A4 or A3. The SVG is vector, so it prints sharp at any size — from a sticker to a canvas.

How do I 3D print the keychain?

Switch to “3D print”, set the length and thickness, and download the STL. Open it in your slicer, lay it flat (it already is), and print — no supports needed. PLA at 0.2 mm layers works well. A thickness of 3 mm or more makes a sturdy keychain.

Can I make it two colours?

Choose the plaque, then add a filament (colour) change in your slicer at the base thickness — the wave prints in the second colour.

Are my recordings uploaded?

No. Your audio is analysed in your browser on your own device and never sent anywhere.

Can I sell what I make?

The designs and models you make are yours. Make sure you have the right to use the recording, and note that the fonts are open-licensed for commercial use.

Is it free?

Yes — free, no sign-up and no watermark, supported by the ads on the page.
