The project SoniControl will be presented at the “Tag der offenen Tür” of the Federal Ministry of Science, Research, and Economy on the Austrian National Holiday (26.10.2017). The project will be shown from 10am to 4pm! We hope to see you there to show you a demo of our prototype!
The SoniControl Project will be presented at this year’s ARS Electronica festival from September 7 – 10. See our live demo of how ultrasonic communication works and how we detect and mask it! You can find us in Postcity Linz, first floor, Room No. 11. We are looking forward to see you there!
We have recently finished our real-time ultrasonic signal detector. The detector is able to detect different types of transmission technologies and is robust to various types of noise sources (e.g. broadband noise), music and speech artifacts. Now we will port it to native code and integrate it into our Android App!
A recent study of TU Brunswick (Germany) reveals that many more Apps than expected use ultrasonic information exchange. More: here. The study can be found here. The SoniControl Project Team members currently work on real-time audio processing methods that enable a robust detection of ultrasonic information.
We have compiled a set of ultrasonic audio recordings of different mobile apps including Google Nearby-based apps. Since ultrasonic sound is inaudible we have made the sounds visible (by computing spectrograms) and audible (by shifting their pitch to the audible range). The entire dataset can be downloaded under “Ressources” on the SoniControl webpage.
We have published our SoniControl Wiki which contrains a comprehensive collection of links, literature and background information about ultrasonic communication technology. You find the Wiki under “Resources”!
P3TV has compiled a TV report about the SoniControl project. The report can be found here!
The OE1 radio programme “Digital-Leben” reported about the SoniControl project, more here.
Soni Control wins the pitch contest of the Netidee Open Source Community Camp. Special thanks goes to Alexandra Müller and Alexandra Negoescu for their great support.
