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.

A method for rendering a spatial audio signal that represents a sound field in a selectable viewpoint audio environment that includes one or more audio objects associated with respective audio content and a respective position in the audio environment. The method includes receiving an indication of a selected listening position and orientation in the audio environment; detecting an interaction concerning a first audio object on basis of one or more predefined interaction criteria; modifying the first audio object and one or more further audio objects linked thereto; and deriving the spatial audio signal that includes at least audio content associated with the modified first audio object in a first spatial position of the sound field that corresponds to its position in the audio environment in relation to said selected listening position and orientation, and audio content associated with the modified one or more further audio objects.

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.

The description relates to modeling acoustic effects in scenes with dynamic portals. One implementation includes obtaining a representation of a scene having a plurality of portals and simulating sound travel in the scene using a plurality of probes deployed in the scene. The implementation also includes determining acoustic parameters for initial sound traveling between respective probes based at least on the simulating. The implementation also includes identifying one or more intercepted portals in the scene that are intercepted by a particular initial sound path from a particular source location to a particular listener location, using particular acoustic parameters for the particular source location and the particular listener location.

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.

Provided is a signal processing device including a control unit configured to control each of a plurality of actuators configured to drive a display unit on the basis of an acoustic signal, in which the plurality of the actuators is provided for respective regions of the display unit, and the control unit executes low band component reduction processing of reducing a low band component of an acoustic signal of the region for driving the actuator on the basis of luminance of an image to be displayed in the region of the display unit.

A device for generating a multitude of loudspeaker signals based on a virtual source object which has a source signal and a meta information determining a position or type of the virtual source object. The device has a modifier configured to time-varyingly modify the meta information. In addition, the device has a renderer configured to transfer the virtual source object and the modified meta information to form a multitude of loudspeaker signals.

A signal processor includes an input unit that receives a first audio signal and a second audio signal including mutually correlated components, a delay unit that delays the first audio signal received at the input unit by a prescribed delay time, a synthesis unit that synthesizes the first audio signal having been delayed by the delay unit with the second audio signal received at the input unit, and outputs a third audio signal resulting from synthesis, and a frequency band restriction unit that restricts a level of the first audio signal before the synthesis in a prescribed frequency band including a frequency of a dip occurring at a lowest frequency among a plurality of dips occurring in a frequency characteristic of the third audio signal as a result of the synthesis performed by the synthesis unit.
