Demo: Riding the Non-linearities to Record Ultrasound with Smartphones
Page 189
Abstract
We demonstrate that high frequency ultrasonic sounds can be designed to become recordable by unmodified smartphone microphones, while remaining inaudible to humans. The core idea lies in exploiting nonlinearities in microphone hardware with a combination of ultrasound frequencies. These frequencies can be regulated to carry data bits, thereby enabling an acoustic (but inaudible) communication channel to today's microphones. Other applications include jamming spy microphones in the environment, live watermarking of music in a concert, and even acoustic Denial-of-Service (DoS) attacks.

BackDoor: Making Microphones Hear Inaudible Sounds
MobiSys '17: Proceedings of the 15th Annual International Conference on Mobile Systems, Applications, and ServicesConsider sounds, say at 40kHz, that are completely outside the human's audible range (20kHz), as well as a microphone's recordable range (24kHz). We show that these high frequency sounds can be designed to become recordable by unmodified microphones, ...
Deep Room Recognition Using Inaudible Echos
Recent years have seen the increasing need of location awareness by mobile applications. This paper presents a room-level indoor localization approach based on the measured room's echos in response to a two-millisecond single-tone inaudible chirp emitted ...
Stereophonic acoustic echo cancellation and two-channel adaptive filtering: an overview
Stereophonic acoustic echo cancellation SAEC, has been studied since the early 1990s. Because of spatial realism, two-channel audio is now becoming more interesting in a number of hands-free applications such as teleconferencing, multi-participant ...
