Welp, my work is toast.

PhonoPaper did NOT make sound out of my 132x72 uploaded digital image, and its miserably failed attempt took half an hour to complete.

A whole new world

Love this! So tactile a way to store and play back sound. Experimental and sci-fi like results. Try placing physical objects on top of the paper as well. And try the blank grid template from the warmplace.ru site. This is fantastic.

Best App in the store

I don’t know what went through the mind of the genius who made this app, but if you only need one, look no further.
Don’t forget to turn the free mode on to fully enjoy the experience.

FAQ

What does PhonoPaper do?

PhonoPaper is a camera app that allows you to play back pictures containing encoded sound, known as PhonoPaper-codes. It also enables you to create your own codes by recording up to 10 seconds of sound and converting it into an image.

How do I use PhonoPaper to play sound codes?

Launch the app, point your camera at the code, and smoothly scan the picture from left to right. Ensure the code is parallel to the frame and the black markers are fully visible. If smooth scanning is difficult, enable automatic scanning by pressing the record button.

Can I create my own sound codes?

Yes, you can create your own PhonoPaper-codes. The app allows you to record up to 10 seconds of sound from your microphone and then converts this audio into a visual code that can be played back later.

Is PhonoPaper compatible with my device?

The provided information does not specify exact compatibility requirements. However, as a camera app, it would typically require a device with a functioning camera and sufficient processing power to run the application.

What are some examples of how PhonoPaper can be used?

PhonoPaper can be used for various creative purposes, such as embedding voice messages or music onto physical items like t-shirts or postcards, creating audio labels for records, including audio examples in books, sending secret messages, or for art experiments.
