Tiltification is a spirit level app for mobile phones utilizing psychoacoustic sonification to enable users level their phones for the sake of leveling furniture or taking perfectly horizontal photos. With over 20,000 downloads this app really reached the masses.

But the sound is … terrible! At least for the majority of people who never got in contact with sonification before.

If you have any questions about this workshop, please contact Tim Ziemer.

Can you do it better? This is your chance:

Sonic Tilt Competition

1. Download and install Sonic Tilt, our open-source version of Tiltification.

2. Kick out our nasty sound and replace it with your own sonification design.

3. Compile the app, document how your sonification works and

4. Hand it in for the Sonic Tilt Competition @ICAD2023 using the Overleaf LaTeX Template or the LaTeX Template!

Except for Pure Data, no programming skills are necessary! Are you an artists, sound designer, researcher, student, engineer, or a creative person from any other field? Then you are welcome to participate in the competition for the best sonification design.

Please hand in your compiled app together with a short paper that includes your own app name, an explanation of your concept, a documentation of your sonification implementation, and ideally a link to demo videos and/or the description and results of a user study or any other evaluation of your sonification, and a reference to our papers on Tiltification ( and An exemplary short paper can be found under

For ICAD2023, please prepare a short (5 minutes) teaser/demonstration of your app.

An expert jury will test the apps and select the winning app that seems most promising to reach the masses; not only audio enthusiasts and sonification experts. The jury will be announced soon. All submitted documentations will be published as an article collection, but not as scientific, peer-reviewed papers.

Important Dates

– The deadline for submitting the app and the documentation is 12th May 2023

– The presentation of your apps and the declaration of the winner will take place @ICAD2023 online, and in Norrköping, Sweden.

– If you only plan to participate in the Sonic Tilt competition (not the ICAD conference) no participation fees will be charged, but you can only participate in the presentations of all submitted Sonic Tilt apps

What Requirements should your Sonification Design fulfill?

Your sonification design should receive an x– and a y-angle to control a sonification that guides the user towards the (x = 0, y = 0) coordinate. This coordinate is reached, when the smartphone is leveled. Your version of Tiltification may be:

– easy to learn and understand

– super-precise

– engaging and fun to use

– pleasant to listen to

– …
