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.
