Embodiments that generate multiple haptic effects receive a first haptic effect signal having a first priority and corresponding to a first haptic effect, and receive a second haptic effect signal having a second priority and corresponding to a second haptic effect. When the first priority is less than the second priority, embodiments generate an interaction parameter using the second haptic effect signal. When the second priority is less than the first priority, embodiments generate the interaction parameter using the first haptic effect signal. Embodiments then apply a drive signal to a haptic output device according to the interaction parameter, where the drive signal causes the first haptic effect and the second haptic effect to be generated by the haptic output device concurrently.

The contained Pass And Limit Modulator removes approximately 50% common or in phase information from two inputs as compared to summing both inputs. This output can be used in a whole building music system or in a mono amplitude modulated radio transmission down-mixed from stereo audio content. The center channel (dialogue) is lowered 50% as not to overpower the music. With the Active Channel Crossover System the center channel is further processed and mixed to obtain multiple output channels. Interactive left and right channel frequency decomposition of a stereo signal is performed for optimum reproduction of a down converted front center channel. This way channel removal speed is respective to the frequencies removed. Further processing reduces the interactive left and right channel frequency decomposed content within the center channel output. As a result, the down-mixed front center channel is reproduced more closely as intended to be heard in its original stereo form. Further processing within the Active Channel Crossover System produces a balanced multi channel music system.

In some examples, immersive audio rendering may include determining whether an audio signal includes a first content format including stereo content, or a second content format including multichannel or object-based content. In response to a determination that the audio signal includes the first content format, the audio signal may be routed to a first block that includes a low-frequency extension and a stereo to multichannel upmix to generate a resulting audio signal. Alternatively, the audio signal may be routed to another low-frequency extension to generate the resulting audio signal. The audio signal may be further processed by performing spatial synthesis on the resulting audio signal, and crosstalk cancellation on the spatial synthesized audio signal. Further, multiband-range compression may be performed on the crosstalk cancelled audio signal, and an output stereo signal may be generated based on the multiband-range compressed audio signal.

Loudspeaker systems, which for technical reasons are not suitable for emitting strong bass signals, can use so-called virtual bass systems. Therein, low frequencies are replaced by their harmonics. However, virtual bass cannot always adequately replace real bass, such that tonal discrepancies may result. Methods and systems are disclosed to improve the bass reproduction of virtual bass by mixing the generated harmonics with a reduced original bass component of the input audio signal. The mixing ratio of this blend can be variable and can be determined automatically. For example, the mixing ratio can change when a level threshold is exceeded, when a temperature rises above/drops below a threshold, a calorimetric threshold is exceeded, or at fixed times of day.

A three-dimensional (3D) audio reproducing method and apparatus is provided. The 3D audio reproducing method may include receiving a multichannel signal comprising a plurality of input channels; and performing downmixing according to a frequency range of the multichannel signal in order to format-convert the plurality of input channels into a plurality of output channels having elevation.

A method for encoding an input audio stream including the steps of obtaining a first playback stream presentation of the input audio stream intended for reproduction on a first audio reproduction system, obtaining a second playback stream presentation of the input audio stream intended for reproduction on a second audio reproduction system, determining a set of transform parameters suitable for transforming an intermediate playback stream presentation to an approximation of the second playback stream presentation, wherein the transform parameters are determined by minimization of a measure of a difference between the approximation of the second playback stream presentation and the second playback stream presentation, and encoding the first playback stream presentation and the set of transform parameters for transmission to a decoder.

Systems and methods can provide an elevated, virtual loudspeaker source in a three-dimensional soundfield using loudspeakers in a horizontal plane. In an example, a processor circuit can receive at least one height audio signal that includes information intended for reproduction using a loudspeaker that is elevated relative to a listener, and optionally offset from the listener's facing direction by a specified azimuth angle. A first virtual height filter can be selected for use based on the specified azimuth angle. A virtualized audio signal can be generated by applying the first virtual height filter to the at least one height audio signal. When the virtualized audio signal is reproduced using one or more loudspeakers in the horizontal plane, the virtualized audio signal can be perceived by the listener as originating from an elevated loudspeaker source that corresponds to the azimuth angle.

A display device includes a display panel which includes a first substrate, a second substrate, and a light emitting element layer disposed between the first substrate and the second substrate and outputting light to the second substrate, a first sound generator which is disposed on a surface of the first substrate and outputs sound by vibrating the display panel, and a first buffer member which is disposed on the surface of the first substrate, where a height of the first buffer member is smaller than that of the first sound generator.

An information processing apparatus acquires information about designation of a position of a virtual viewpoint related to a virtual viewpoint image generated based on image capturing by a plurality of cameras, and decides, based on the information, a virtual listening point for generating an audio signal based on sound pickup at a plurality of sound pickup points.

A method for conveying to a listener a directionality-preserving pseudo low frequency psycho-acoustic sensation of a multichannel sound signal, including: deriving from the sound signal, by a processing unit, a high frequency multichannel signal and a low frequency multichannel signal, generating a multichannel harmonic signal, the loudness of at least one channel signal of the multichannel harmonic signal substantially matching the loudness of a corresponding channel in the low frequency multichannel signal; and at least one interaural level difference (ILD) of at least one frequency of the at least one channel pair of the multichannel harmonic signal substantially matching an ILD of a corresponding fundamental frequency in a corresponding channel pair in the low frequency multichannel signal; and summing the harmonic multichannel signal and the high frequency multichannel signal thereby giving rise to a psychoacoustic alternative signal.
