SYSTEMS AND METHODS OF SPATIAL AUDIO PLAYBACK WITH ENHANCED IMMERSIVENESS
A method of playing back audio content with improved immersiveness can include receiving, at a playback device, audio input including vertical content having a high-frequency portion and a low-frequency portion. The playback device can face along a first sound axis and comprise an up-firing transducer configured to direct sound along a second sound axis that is vertically angled with respect to the primary sound axis and a side-firing transducer or array configured to direct sound along a third axis that is horizontally angled with respect to the first sound axis. The low-frequency portion of the vertical content can be played back via the side-firing transducer or array, while the high-frequency portion of the vertical content can be played back via the up-firing transducer.
Orientation-aware surround sound playback
Example embodiments disclosed herein relate to orientation-aware surround sound playback. A method for processing audio on an electronic device that includes a plurality of loudspeakers is disclosed, the loudspeakers arranged in more than one dimension of the electronic device. The method includes, responsive to receipt of a plurality of received audio streams, generating a rendering component associated with the plurality of received audio streams, determining an orientation dependent component of the rendering component, processing the rendering component by updating the orientation dependent component according to an orientation of the loudspeakers and dispatching the received audio streams to the plurality of loudspeakers for playback based on the processed rendering component. Corresponding system and computer program products are also disclosed.

SYSTEMS AND METHODS FOR PROVIDING AUGMENTED AUDIO
A system for providing augmented spatialized audio in a vehicle, including a plurality of speakers disposed in a perimeter of a cabin of the vehicle; and a controller configured to receive a position signal indicative of the position of a first user's head in the vehicle and to output to a first binaural device, according to the first position signal, a first spatial audio signal, such that the first binaural device produces a first spatial acoustic signal perceived by the first user as originating from a first virtual source location within the vehicle cabin, wherein the first spatial audio signal comprises at least an upper range of a first content signal, wherein the controller is further configured to drive the plurality of speakers with a driving signal such that a first bass content of the first content signal is produced in the vehicle cabin.
Audio System Height Channel Up-Mixing
Audio system height channel up-mixing that is configured to develop two or more height channels from audio sources that do not include height-related encoding. The up-mixing involves determining correlations and normalized channel energies between input audio signals. At least two height channels (e.g., left and right height audio signals) are developed from the correlations and normalized energies.

Method for audio reproduction in a multi-channel sound system
The invention relates to a method for reproducing audio in a multi-channel sound system including two input signals (L and R), wherein output signals are generated for different sound perception levels. In order to develop said method in such a way that audio can be reproduced within a larger range of applications in a multi-channel sound system, according to the invention, only a lower sound perception level (7) and a higher sound perception level (6) are generated, and a maximum of six output signals are generated, a maximum of two output signals being allocated to the lower sound perception level (7) and a maximum of four output signals being allocated to the higher sound perception level (6).
