A system and method for generating a virtual soundstage in a listening environment having a compact speaker array centrally positioned in a listening environment. A listener is sitting offset from the speaker array and the virtual soundstage is generated in front of a listener. A signal processing unit is configured to receive an incoming audio signal, to process left and right channel signals of the incoming audio signal to generate a null, and to steer the null toward one ear of a listener thereby generating a virtual sound source that is offset from the center of the listening environment. Virtual sound sources are generated in front of, to the left of, and to the right of the listener.

The information processing device includes: a sensor that detects an object; an open ear style earpiece that is worn on an ear of a listener, and includes an acoustics generation unit, and a sound guide portion that transmits a sound generated by the acoustics generation unit into an earhole; and a processing unit that processes sound information of a sound source, the sound information being generated by the acoustics generation unit, the processing unit acquiring the sound information of the sound source corresponding to the object detected by the sensor, and a process of localizing a sound image of the acquired sound source while varying a position of the sound image in accordance with a position in a three-dimensional acoustic space, the position in the three-dimensional acoustic space corresponding to a position of the detected object.

Example techniques relate to audio generation in a media playback system. Based on one or more first functions and first characteristics of an area, the system may generate first audio that includes a first audio signal and a second audio signal. The system provides the first audio signal to at least one first audio driver and the second audio signal to at least one second audio driver, thereby causing a first playback device and a second playback device to play back the first audio synchronously. The system receives second characteristics of the area and based on one or more second functions and the second characteristics, generates second audio comprising a third audio signal and a fourth audio signal. The system provides the third audio signal to the at least one first audio driver and the fourth audio signal to the at least one second audio driver.

Disclosed is an audio signal processing device. The audio signal processing device includes a receiving end configured to receive a 2-channel stereo signal and a processor configured to process the 2-channel stereo signal. The processor is configured to filter the 2-channel stereo signal using a spatial distortion removal filter and output the filtered 2-channel stereo signal to a speaker including two or more channels. The spatial distortion removal filter is a filter for offsetting distortion that occurs when the output signal is transmitted from the speaker to a listener, and includes an ipsilateral filter applied to an ipsilateral signal of the 2-channel audio signal and a contralateral filter applied to a contralateral signal of the 2-channel audio signal.

In a method for reproducing sound of a data object, a voice signal of a data object is split into a first sub-band signal and a second sub-band signal, and speaker driver signals are generated to produce sound of the object by a two-way speaker system in which the first sub-band signal drives a tweeter or high frequency driver and the second sub-band signal drives a woofer or low frequency driver. In another aspect, the first and second sub-band signals are spatialized as virtual sources that are in different locations. Other aspects are also described and claimed.

A display apparatus including a display panel configured to display an image in a front direction; a main speaker provided on a rear surface of the display panel; and an auxiliary speaker provided on the rear surface of the display panel, the auxiliary speaker being configured to output a sound in a rear direction opposing the front direction.

Embodiments relate to audio processing for opposite facing speaker configurations that results in multiple optimal listening regions around the speakers. A system includes a left speaker and a right speaker in an opposite facing speaker configuration, and a crosstalk cancellation processor connected with the left speaker and the right speaker. The crosstalk cancellation processor applies a crosstalk cancellation to an input audio signal to generate left and right output channels. The left output channel is provided to the left speaker and the right output channel is provided to the right speaker to generate sound including multiple crosstalk cancelled listening regions that are spaced apart.

New method for improving the reproduction of stereophonic modulations in cars.

According to this method, in first step the level distortion in uncorrelated isobar mode is canceled first by means of the balance adjustment, in a second stage the center of the sound image is positioned at the center of the sound scene in the isobaric correlated mode in delaying the modulation feeding the loudspeaker closest to the conductor and in a third stage by canceling the stereophonic phase distortion in the isobaric mode correlated by means of a phase equalizer.
