A display apparatus according to an embodiment of the present disclosure includes: a thin plate-like display cell that displays an image; M exciters that are disposed on a back surface side of the display cell, and vibrate the display cell; and a driving section that drives the display cell and the M exciters.
Surround sound location virtualization
A computer program product having a non-transitory computer-readable medium including computer program logic encoded thereon that, when performed on a surround sound audio system that is configured to render left front, right front, and center front audio signals, and also render left and right near-field binaurally-encoded audio signals, causes the surround sound audio system to develop the left and right near-field binaurally-encoded audio signals, and provide the left near-field binaurally-encoded audio signal to a left non-occluding near-field driver and provide the right near-field binaurally-encoded audio signal to a right non-occluding near-field driver.
METHOD AND SYSTEM FOR DYNAMIC VOICE ENHANCEMENT
The present disclosure provides a method and system for voice enhancement. The method and system of the present disclosure may simultaneously perform signal processing of two paths on an input signal. The first path signal processing includes receiving an audio source input and performing dynamic loudness balancing on the audio source input based on a first gain control parameter. The second path signal processing includes: performing voice detection on the audio source input and calculating a detection confidence; and calculating a second gain control parameter based on the detection confidence. The first path signal processing and the second path signal processing may be synchronous or asynchronous. The method of the present disclosure also includes updating the first gain control parameter with the second gain control parameter calculated by a second processing path and performing the first path signal processing based on the updated first gain control parameter.
Manipulation of Playback Device Response Using Signal Processing
An example playback device receives left and right channels of audio content and generates a center channel of the audio content by combining at least a portion of the left right channels. The playback device generates first and second side channels of the audio content by combining the center channel and a difference of the left channel and the right channel and combining the center channel and an inverse of the difference of the left channel and the right channel, respectively. The playback device plays back the center channel of the audio content according to a first radiation pattern having a maximum aligned with a first direction, the first side channel according to a second radiation pattern having a maximum aligned with a second direction, and the second side channel according to a third radiation pattern having a maximum aligned with a fourth direction.
COLORLESS GENERATION OF ELEVATION PERCEPTUAL CUES USING ALL-PASS FILTER NETWORKS
A system includes one or more computing devices that encode spatial perceptual cues into a monaural channel to generate a plurality of output channels. A computing device determines a target amplitude response for the mid and side channels of the plurality of output channels, defining a spatial perceptual associated with one or more frequency-dependent phase shifts. The computing device determines a transfer function of a single-input, multi-output allpass filter based on the target amplitude response and determines coefficients of the allpass filter based on the transfer function, and processes the monaural channel with the coefficients of the allpass filter to generate the plurality of channels having the encoded spatial perceptual cues. The allpass filter is configured to be colorless with respect to the individual output channels, allowing for the placement of spatial cues into the audio stream to be decoupled from the overall coloration of the audio.
AUDIO INTEGRATION OF PORTABLE ELECTRONIC DEVICES FOR ENCLOSED ENVIRONMENTS
Implementations of the subject technology provide for audio integration of portable electronic devices into enclosed environments. A portable electronic device may be carried, by a user, into an enclosed environment, such as into an enclosure of a building, a room, or other apparatus. One or more remote speakers may be disposed in the enclosed environment. The remote speaker(s) may be operated in cooperation with the portable electronic device to spatially coordinate audio output from the remote speaker(s) with video content displayed by the portable electronic device.
System and method for an audio reproduction device
System and method for enhancing audio reproduced by an audio reproduction device with a first channel and second channel is described. X samples of audio signals are received and stored in a portion of an input buffer with 2x positions and rest of the x positions are padded with zero for both the channels. Contents of the input buffer are transformed to frequency domain (FD) components. FD components are multiplied with a first filter coefficient to generate FD components with short echo effect and with a second filter coefficient to generate FD components with long echo effect. Then, they are converted to time domain (TD) components with short echo effect and TD components with long echo effect. Selective TD components with short echo effect and long echo effect are combined to generate a convolved first channel output and a convolved second channel output.
Sum-difference arrays for audio playback devices
In some embodiments, a method comprises receiving audio content comprising left input channel signals and right input channel signals, and generating first and second input signals from the left and right input channel signals. The first input signal is based on a sum of the left and right input channel signals, and the second input signal is based on a difference of the left and right input channel signals. An array transfer function is applied to the first and second input signals to produced audio output signals, which can be provided to a plurality of audio transducers on one or more playback devices.
Media processing device, media broadcasting system, and media processing method
The present disclosure relates to a media broadcasting system, including a first broadcasting device, a second broadcasting device and a processing device. The first broadcasting device and the second broadcasting device are respectively arranged at a first side and a second side of the media broadcasting system.
