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.
Display Device
The display device is provided which includes a signal processing unit that processes an image signal and a sound signal, a plate-like panel unit that displays an image according to the image signal, and a vibration unit that is deployed on the rear face side of the panel unit and causes the panel unit to vibrate in response to the sound signal. The vibration unit includes a plurality of vibrators, and the signal processing unit outputs the sound signal not only to a sound output vibrator that is a vibrator of an output target of the sound signal from among the plurality of vibrators but also to a dispersion sound output vibrator that is a vibrator of a dispersion target of the sound signal. The present technology can be applied, for example, to a television receiver.
Bidirectional propagation of sound
The description relates to rendering directional sound. One implementation includes receiving directional impulse responses corresponding to a scene. The directional impulse responses can correspond to multiple sound source locations and a listener location in the scene. The implementation can also include encoding the directional impulse responses to obtain encoded departure direction parameters for individual sound source locations. The implementation can also include outputting the encoded departure direction parameters, the encoded departure direction parameters providing sound departure directions from the individual sound source locations for rendering of sound.
SOUND COLLECTION LOUDSPEAKER APPARATUS, METHOD AND PROGRAM FOR THE SAME
Provided is a sound pickup loudspeaker apparatus which suppresses the influence of feedback produced when adding a speaker while also reducing a sense of unnaturalness in a sound image. The sound pickup loudspeaker apparatus collects a target sound emitted from a first seat in the vehicle, plays back the collected target sound to a listener seated in a second seat in the vehicle from a second sound amplifying device disposed in a direction different from the first seat from the perspective of the listener, and furthermore plays back the collected target sound to the listener from a first sound amplifying device disposed in the same direction as the first seat from the perspective of the listener. The apparatus multiplies the target sound by a first gain and outputs the target sound to the first sound amplifying device; delays the target sound by an amount of time obtained by adding a time for achieving a precedence effect to a delay time of the first sound amplifying device relative to the second sound amplifying device; and multiplies the delayed target sound by a second gain and outputs the target sound to the second sound amplifying device. A first gain adjustment unit adjusts the first gain to a low value and a second gain adjustment unit adjusts the second gain to a high value.

AUDIO PROCESSING TO COMPENSATE FOR TIME OFFSETS
A method of processing each of a first plurality of temporal windows of first and second input audio signals to generate first and second output audio signals comprises (a) detecting a time offset between respective portions of the first and second input audio signals corresponding to a given temporal window by: (i) detecting a correlation between one or more properties of the respective portions according to each of a group of candidate time offsets under test; and (ii) selecting, as a detected time offset for the given temporal window, an offset for which the detecting step (i) detects a correlation which meets a predetermined criterion such as greatest correlation; and (b) for each of a second plurality of temporal windows, generating a portion of the first and second output signals by applying a relative delay between portions of the first and second input audio signals in order to correct one or both of the input audio signals to generate a pair of output audio signals (such as a stereo pair) having a reduced temporal disparity between the audio content of the two signals.
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.
AUDIO SYSTEM SPEAKER VIRTUALIZATION
Embodiments may relate to an audio system for playback of an audio signal, for example in a motor vehicle. The audio system may include a virtualization speaker located in a position that would be in front of a listener of the audio system. The audio system may further include a user speaker located in a position that would be behind a listener of the audio system. In some embodiments the virtualization speaker may be configured to play a virtualization audio signal while the user speakers are configured to play an audio signal which at least partially overlaps the virtualization audio signal. In some embodiments the virtualization audio signal may be at a different volume or a different frequency range than the audio signal. Other embodiments may be described or claimed.
METHOD FOR INFLUENCING AN AUDITORY DIRECTION PERCEPTION OF A LISTENER AND ARRANGEMENT FOR IMPLEMENTING THE METHOD
A method for influencing an auditory direction perception of a listener, and to an arrangement for implementing the method is disclosed, to provide a solution, by means of which the improvement of the suppression of the auditory localization of a direction of one or more real sources S.sub.1 of a sound projecting audio playback system is achieved in that a localization-masking additionally generated sound entity is provided and is radiated by means of the real source S.sub.1 with a directional effect in a defined direction.
