Your recording stays with you

Klangform needs no server for your recording. Your browser calculates the sound wave. Only the numbers for the shape go into the order, never the sound itself. No cookies, no tracking.

Questions

Frequently asked questions about the sound wave keychain

What can I record?

Anything with a sound: a name, an “I love you”, a laugh, a heartbeat from an ultrasound video, a voice message or a few seconds of your song. 2 to 5 seconds work best.

Can I use a voice message or a video?

Yes. Instead of recording, you can upload an audio or video file, for example a saved voice message or an ultrasound video. Then you choose the part you want.

Is my recording uploaded?

No. The recording is only analysed in your browser. It becomes a row of numbers for the shape. The sound cannot be restored from these numbers.

How much does a sound wave keychain cost?

A keychain costs €7 to €9 depending on the size, a pendant €7, a Christmas ornament from €6. Shipping within Germany costs €2.95. All prices are final prices.

Do you ship outside Germany?

How long does delivery take?

We print your piece and ship it within 7 days of payment. Printed parts are sold out right now. The print file comes by email after payment.

Is a chain or ribbon included?

No. Pendants come without a chain, bookmarks and Christmas ornaments without a ribbon. You find matching chains, ribbons and key rings on our recommendations page.

Can I print it myself?

Yes. Instead of the printed part you can order the STL file for €2 and print it on your own 3D printer.
