Abstract: An input audio signal is separated into input audio signal components (X(k,b)). A set of two or more band branches provides output audio signal components (Y(k,b)). The set of band branches comprises one or more compressor branches Each compressor branch compresses a respective input audio signal component (X(k,b)) into a respective output audio signal component (Y(k,b)). A summed audio signal (y(t)) is generated by summing the output audio signal components (Y(k,b)). A residual audio signal (v(t)) is a difference between the input audio signal and the summed audio signal(y(t)) A virtual bass signal (w(t)) comprises one or more harmonics of the residual audio signal (v(t)). An output audio signal is generated by summing the summed audio signal (y(t)) and the virtual bass signal (w(t)).

Abstract: An apparatus provides personalized binaural audio rendering of an input signal. The apparatus has a left ear transducer configured to generate a left ear audio signal and a right ear transducer configured to generate a right ear audio signal. Moreover, the apparatus has processing circuitry configured to determine, based on a current target direction of the input signal, an adjusted current target direction using a personalized adjustment function that describes a functional relationship between a plurality of reference target directions of a reference sound signal and a plurality of perceived reference target directions of the reference sound signal as perceived by a user. The processing circuitry is further configured to implement a target direction renderer configured to generate based on the input signal and the adjusted target direction a first driving signal for driving the left ear transducer and a second driving signal for driving the right ear transducer.

Abstract: A device and a method are provided for producing a sound field are disclosed. The device comprises a plurality of loudspeakers arranged at a plurality of locations within a plane and a processing circuitry configured to drive the plurality of loudspeakers. A first subset of the plurality of loudspeakers defines a first rhombus within the plane and a second subset of the plurality of loudspeakers defines a second rhombus within the plane. The first rhombus is oriented substantially perpendicular to the second rhombus. Further subsets of the plurality of loudspeakers may define further rhombic sub-arrays. The audio device may be implemented as a soundbar or a sound panel, which provides a richer sound experience.
