Abstract
The various embodiments relate generally to systems, devices, apparatuses, and methods for providing audio streams to multiple listeners, and more specifically, to a system, a device, and a method for providing independent listener-specific audio streams to multiple listeners using a common audio source, such as a set of loudspeakers, and, optionally, a shared audio stream. In some embodiments, a method includes identifying a first audio stream for reception at a first region to be canceled at a second region, and generating a cancellation signal that is projected in another audio stream destined for the second region. The cancellation signal and the first audio steam are combined at the second region. Further, a compensation signal to reduce the cancellation signal at the first region can be generated.
